Where R You?

Got any kids with 'R' problems in your caseload? Yeah, I thought so. From what we hear from speech-language pathologists, most everyone has at least one with that pesky and tough-to-correct speech issue. Video Voice has a number of games and displays that can help, and the one I'm currently excited about is the Formant Multi-Frequency Spectral Display included in the last release (V3.0.127). This new display uses live feedback to help speakers learn about production of 'R' (and other sounds, too). With it they can quickly learn how changes in articulator position make all the difference in what sound they're producing.

Off hand, I can't think of a single, commonly-used word that more simply defines the problem of 'R' and its oft-confused 'OO' than “were.” It's a pure combination of those two sounds, and producing it correctly requires subtle and largely invisible change in tongue position, or “bunching,” to move smoothly between them. The immediate feedback in the Spectral display can be powerful in illustrating when this is, or is not, happening, and it provides a facility for practicing and learning the differences in production of the two.

Let's take a closer look. Now, I'm going to assume that you have either purchased Video Voice or have downloaded the Free Trial (at www.videovoice.com) to explore what it offers for therapy, and do a little follow-along to give you some basis on how this display works. (And if you haven’t downloaded the trial, why not? There’s absolutely no charge or ongoing obligation!)

Start by accessing the Spectral Display from the Formant Menu (Multi-Frequency-Spectral).

First, lets do some practice voicing. Click Start to activate the display, then vocalize. Say “were,” slowly, focusing on the F2 area in particular. You'll see very little blue when you're saying the 'woo' part of the word, but a great deal more when you hit (and sustain) the 'er'.

Also notice that as you speak, you see movement in all three Formant frequency ranges, and also a “trace” line above them. This is Video Voice averaging and smoothing the speech data into a single line as you speak, and it will be important as we go through this exercise.

The feedback is instantaneous! And, like speech, it's also fleeting. When you stop  vocalizing, the visual disappears. So we need a way to freeze a target so the feedback becomes more concrete.

Say “were” slowly again, sustaining the 'r'. As you see the blue F2 region and associated trace line expand upward with that sound, click the Use button. Video Voice will draw and hold a light trace line showing what the frequencies in the F1, F2 and F3 regions were at the point where you captured the sound with Use.  Now you have a “model” of the desired sound.

Now, try saying “were” again with the model trace on the screen. Say it slowly so you can see how the 'woo' and 'r' look, as well as the transition between the sounds. When you reach the 'r' part of the word, the blue F2 area should move up and touch the trace line.

The 'oo' in "were"

The 'r' in "were"

Pretty darned cool, isn't it?  It's a great way to practice sounds that are similar, but differ in important ways.

By the way, there's no scoring in this display, but you can always click the Reward button to activate a graphic animation when the speaker has reached the goal of producing that 'R' sound consistently.

And, if you find having all three frequencies shown at once confusing for this or any other sound, you can restrict the display and show only the most relevant one(s) by clicking the “ON” label(s) below the F1, F2 or F3 ranges. It will change to OFF, and you’ll no longer see that area of the display.

The live nature of this display makes it most useful for sounds that can be sustained, of course. In addition to 'R' and 'OO,' you'll also see big differences between sounds like ‘S’ and ‘SH,’ particularly in the F2 and F3 ranges. Give it a try!

We hope you have fun experimenting with this and other Video Voice displays and games to see how they can assist with your 'R' cases, as well as other speech problems in your caseload.

Help!!

What do you do when you need help communicating information about speech with those in your caseload and getting them to understand how to make changes in their voices? The little boy who just can't seem to find the right tongue position for his 'R's. The girl whose slushy 'S' is driving you crazy. The youngster who just won't do purposeful voicing.

There are, of course, a plethora of speech therapy techniques and a number of tools available to streamline the process. One of those tools is the visual feedback on voice production Video Voice provides. We obviously believe its displays and games offer great benefits for communicating about most any aspect of speech development and remediation, and so do the many speech-language pathologists who have added it to their tool kits.

But what do you do when you need help with Video Voice? Used to be, you’d pull out the big user manual and pore through the index for answers. The problem with printed documentation, however, is that it can all too quickly become out of date, especially if the software changes. Since we’re always working on adding to and improving Video Voice, changes are a common and frequent occurrence. We therefore decided not to provide a printed manual, but instead make it an internal, integral part of the software operation. As the program changes, so does its reference material.

On virtually every Video Voice screen, you’ll find a Help button. Clicking it opens the built-in manual to the page appropriate to the area you're using. This internal documentation is not the anemic, sketchy variety many software programs have, the kind that can raise more questions than they answer. Video Voice's Help file contains more than 150 "pages" of information, chock-full of details on what the controls do for you, and how they function. The pages have an on-line "feel" to them, and are loaded with links that easily transport you to other related parts of the manual.

There are other built-in tools, too, like the Help Me Choose interactive guide and the Solutions and Support materials, all of which have buttons/links on the Main Menu. The "tool tips" for controls that appear when you dwell your cursor over them also briefly describe function to let you know if a control is what you need to use.

But sometimes you just really need to talk to somebody! We're proud to offer friendly, responsive support to both existing Video Voice users and those who are evaluating to see how it can meet their needs. You can ask your questions or get suggestions for appropriate use with different speech problems either by phone or email. Most of the time when you call, you'll hear a real person's voice on the other end of the line. If you do happen to get a recorded voice, just leave your name and number, and we'll call you back as soon as we can.

Just the other day a speech-language pathologist who's considering Video Voice called for guidance on what things would be most helpful with children she works with. Her caseload runs the gamut of the autism spectrum, from low-functioning, preschool-aged children who need vocal awareness encouragement to older, fluent ones who need to work on expressive function, particularly increasing pitch range and intonation skills. I was able to make a variety of suggestions for both cases. For the little ones who need to develop understanding that something happens when they use their voices, games like Chat-N-U-Go Choo-Choo and Pitch Painting can communicate that cause and effect. For the older boy who speaks in a monotone, P-A-R Pitch displays can illustrate desired voicing, pitch and fluent intonation in a sentence like "How ARE you?" vs. how it looks and sounds differently when he uses a flat pitch with distinct pauses between words. There are lots of other options, too, but we only talked about those few in our brief conversation.

We all need a little help sometimes, and that includes us. We do our very best to make Video Voice a flexible, easy-to-use tool, but hearing from speech-language pathologists (or others) about how they're using the displays helps us understand what we can do to make it even more effective. Of course we like to hear about things you like, but just as important are the things you don't like. If you have problems, they’re our problems, too, but we can’t fix them if we don’t know they exist. We welcome all feedback, so please give us yours!

In closing, here’s a little musical entertainment that fits the bill, and might just put a smile on your face: http://www.youtube.com/watch?v=606ZcMKXlUg. 

And remember, when you need someone, we're here to help!

Hey, I Have A Voice!

Over the years, we’ve talked with many therapists who have told us they find Video Voice most helpful with young children who come into their programs with little or no awareness of their voices. In particular, profoundly deaf youngsters often start off with no idea that vocalization is even an option. Visual stimulus for those little ones can be a key that unlocks a hidden door, helping them understand that "I have a voice, and something happens when I use it!" 

Video Voice has many options to assist with this first building block of speech. The simplest are those like Pitch Painting, Magic Box (Magic Blocks option), Kaleidoscope and On The Air, in which any sound results in colorful response from the display.

Others like Chat-N-U-Go Choo-Choo and Voice-A-Sketch can be set so that any form of sound onset or ongoing vocalization will result in a change in the display. With Choo-Choo, it can be the train, car or horse moving after a vocal onset or sustained phonation is detected. With Voice-A-Sketch, a picture will be gradually be revealed. You can use these games to start with simple phonation or onsets (then later move to work on volume control, specific sounds and words).

The Up, Up and Away game, the object it to try a balloon across a mountain range. The balloon only moves when voicing is present, and its height is related to the volume level. If the player This encourages vocalization, and allows for work on speaking volume as well.

With the Jumping Jack race game, you can use the More Volume option, but set the volume level required very low. Then, most any vocalization will make Jack run.

Another simple "cause and effect" game option is Laser Master.  In this game, vocalization activates a laser beam and moves an "alien space ship" out into space (off the screen).  Although the general purpose of this game is for pitch and/or volume work, the Duration goal simplifies operation, and any pitch or volume will make the space ship glide across the screen. 

In addition to the games, Video Voice offers other graphic displays to help develop cognition of speech, such as the Formant Multi-Frequency Spectral display and Formant Gobble.  The Spectral display provides visual feedback with a colorful graph of all three Formant frequencies simultaneously.  The Gobble display is like "Pac-Man for speech" - the goal is to eat up a sound pattern.  The live nature of these displays is a very powerful way to illustrate the presence (or absence) of speech.

These are just some of the ways visual feedback can stimulate the awareness and use of voice. Whether you’re working with hearing impaired children, those with autism who need encouragement to develop their speech skills, or youngsters those who are relearning vocal control after a head injury, you’re sure to find something in Video Voice that will pique their interest and get them talking!

Yours in good speech,

The History of Video Voice

Video Voice has a more than 25 year history. It got its start back in 1984, when a team of scientists, one of whom was hearing-impaired, began looking for a way to illustrate speech. The chemistry professor, who had been deaf since birth, decided as a child that he wanted to be a scientist, and understood that he’d need to be able to speak to be successful in that career. So he regularly attended speech therapy and diligently practiced at home between sessions, but was often frustrated to find he’d been practicing the wrong sound. So he and colleagues - an electronic engineer and a software designer - set about creating an electronic device that would illustrate sounds as they were produced. Their design was based on the vowel representation scheme from Grant Fairbanks’ Voice and Articulation Drill Book (©1954), and they  were granted a patent for both the hardware and software.

The first version of Video Voice was based on a small microcomputer called the Interact. Most people haven’t heard of it, but it was one of the first personal computers on the market. It was released about the time of the Radio Shack TRS80. The graphics capabilities were modest, with only a 112x77 pixel resolution (!!) and a total of 8 colors, but it had a built-in analog-to-digital converter, an important capability since speech is analog by nature. The earliest Video Voice models included that computer and an external device called the Speech Analyzer (or "black box") that converted the voice data to digital form as it was sampled.

The inventors’ prototype provided feedback that was pretty meager, nothing more than a few dots on the screen that showed the basic location of a vowel sound. That didn’t seem like it would be interesting for long, so we set about fleshing out the display and software to turn it into a tool that would be motivating - adding color, a model and trial structure, on-screen vowel display, and much more.

As computers gained popularity in schools, therapists started asking for a version that would operate on Apple II/IIgs computers, so we converted the software to operate on those platforms. Then came the Macintosh, and we produced a Mac-based Video Voice. And then one for the IBM PC, first a DOS-based version, then a Windows-compatible one. (During this time, IBM produced its Speech Viewer program, which became widely known, but is no longer available.)

The external Speech Analyzer was retired with the release of Version 3.0. All voice sampling is done through the computer’s internal sound capabilities, and the analysis with our own specialized software routines. This allowed us to greatly expand Video Voice’s capabilities to increase the frequency ranges of sound sampling and add many new games and displays, at a signficantly lower price,.

Expanded capabilities include much wider pitch range to accommodate low-pitched male voices and high-pitched children’s voices (something the Speech Analyzer versions were limited in). We’ve also been able to increase the formant frequency sampling to illustrate and differentiate high frequency sounds like /s/ and /sh/. (The earlier, hardware-dependent versions could detect the presence or absence of high-frequency sounds, but could not tell the difference between them.)

With faster computers with greater capabilities, we’ve been able to greatly enhance the graphics used in Video Voice. They’re still not as fancy or with Xbox-type resolution, because there’s a lot going on "behind the scenes" in the voice sampling and analysis that takes substantial "compute time." And, after all, the point is to illustrate speech, not to be a realistic action game.

To wit, many years back, some folks designed a software interface that integrated with some video games that were then available which had higher resolution graphics and action. It could be programmed to accept 4 words that would control the action of a game (for purposes of this example - "left," "right," "up," and "down"). The goal was to command virtual game player to move around and avoid being attacked by a monster (again, an example). Unfortunately, what hadn’t been considered was the excitement factor in the sound analysis. Targets that were calmly produced when the game was being initially set up, didn’t achieve the desired motion response when the player got excited during the game action and began shouting the words at the screen. Pitch and volume, after all, do affect sound production! This program quickly faded from the scene.

Version 3.0 is the only Video Voice model now being produced. It operates on most Windows operating systems (Windows 2000 and later), and is not dependent on processor speed. In fact, on really fast computers, we actually have to slow some things down. A two-second model, for example, needs to be two-seconds long, even if the computer is capable of displaying the graphics much faster.

That’s the basic history of Video Voice. Development is ongoing, with new things added all the time, so there will still be future chapters written!

Shared Smiles

Probably the most rewarding part of about being involved with Video Voice is hearing stories about how it helps people. We get lots of positive feedback from users, and I thought I’d share a few with you.

A year or so ago, a therapist told us about using the Voice-A-Sketch game with one of her students with fluency problems. She had him try to reveal an entire hidden picture with by sustaining vocalization of a sentence, and he’d been practicing diligently. A teaching aide who was in the room with them as he successfully completed the task spun around in surprise - it was the first time she'd heard him form a complete sentence without stuttering!

A therapist who uses Video Voice with autistic students told us that it really motivates them to participate in speech therapy. In fact, sometimes it's the ONLY thing they will respond to! (Obviously, that’s not the ultimate goal, but at least it’s a start.)

Pitch awareness and control is a common problem for hearing-impaired students, and that was the case with a profoundly deaf third grader. Her voice was shrill and squeaky, so her therapist used the Pitch Painting game to help her learn to lower her pitch. That game represents, pitch as colors in a spectrum, with high pitch appearing as light colors such as yellow and white. The child’s goal was to keep her colors "under pink," and she was able to achieve that goal regularly while using the display. Carry-over is always a challenge, though, so the therapist came up with a creative idea for times when they were not at the computer. She began to sign "under pink" when her pitch was too high, and the child would respond by lowering it. They taught teachers in her other classes to use that sign, too, and all were impressed at how she responded appropriately.

Especially rewarding are the stories come from those who improved their speech skills with the visual feedback.

One of our favorite, long-time Video Voice users shared a story that had made her smile. While she was out shopping one day, a young woman approached her and said "I don't know if you remember me, but you were my speech therapist when I was in school. We used a computer program that helped me learn to say my R's correctly!" This was at least 10 years after the fact, but when she learned her name, she did recall her and their therapy goals. So pleased to be remembered and know she’d made a real difference in that young woman’s life, that she made sure to share the story with us.

Not long ago we received an email from a hearing-impaired woman who had run across the Video Voice website and thought it might be the same program she'd used in therapy about a decade earlier. She said she'd often thought about how Video Voice helped her understand what she needed to do with her voice, and wondered if it was still around. She was pleased to find that it was. Her therapist was the one who suggested the "train game" (Chat-N-U-Go Choo-Choo) to us, and offered guidance in the development of that activity. It was fun to hear that she remembered Video Voice fondly, particularly that activity, and felt she had benefitted from the feedback it provided.

These are just a few of the stories we’ve heard over the years. If you’ve had successes with people in your caseload either while using the Free Trial or full Video Voice program, we’d love to hear from you, too!

Visual Feedback Enhances Speech Therapy Results

The benefits visual feedback offers to both clincians and individuals receiving speech therapy are unquestionable.  Speech is fleeting and intangible by nature, and challenges in interpreting it can be influenced by a number of things, including hearing loss and other auditory processing deficits.  While production of some sounds can be illustrated fairly easily using our mouths, elements such as pitch and volume are essentially invisible.  Having a way to freeze, view and replay a speech production and its components therefore has great value.

Visual feedback changes the nature of the speech therapy process, giving the student or patient a different sense of control.  After all, it is his voice that's represented and recorded, and he has a new way to understand and learn to modify tongue or other articulator position to change the resulting display.  It's no longer a case of what the therapist says he's doing right or wrong, it's what both people see happening on the screen, and it gives them a different way to discuss it.  As more than one therapist has told us, "They can't argue with me anymore!"

For those who have already had years of speech therapy and are bored with the process, visual feedback brings new life to the activities.   Having different games to play and displays to practice sounds, words and connected speech turns therapy into a fun, exciting adventure to be explored and enjoyed.

Video Voice has many entertaining practice formats that keep therapy recipients motivated and eager to succeed in improving their speech skills.  Many provide live feedback on pitch, volume or sounds, so the speaker gets instant response to changes he makes, helping him find and maintain correct production.  Colorful animations and encouraging messages support the therapist by rewarding good performance. 

There are many reasons to consider visual feedback as an adjunct to speech therapy.  If you're not already exploring the benefits, you're missing out on a tool that can expedite progress with your caseload.  You can give Video Voice a try for free to see for yourself how it can enhance your therapy results.  There's no cost to download and explore what it can do for you.  Just pay a visit to http://www.videovoice.com/!

Let's Talk Video Voice!

When starting up a blog, the biggest challenge is figuring out where to start! With the Video Voice Speech Training System, there is a LOT to talk about. It has a long history, having been successfully used by speech therapists in schools, hospitals and clinics for more than 25 years. It has numerous games and displays that provide visual feedback to assist in speech therapy with almost any kind of speech problem, with young children through adults.

Over the years, Video Voice has undergone many changes, getting better with each new version, as we make additions and enhancements based on our own testing and creative thinking, as well as feedback from people using it. Feedback from therapists has historically been an important part of Video Voice development, and we take comments and suggestions seriously. If there’s something someone doesn’t like, we try to modify operation accordingly. If someone has an idea for a new game or display, we do our best to incorporate it.

One example is the Chat-N-U-Go Choo-Choo game, requested by a therapist who had some children in her caseload who were fascinated by trains. In response, we added a game in which sound production makes a train move through a mountain scene. Another therapist really wanted non-violent game graphics in the Bombs Away! game (now called Bulls Eye!), so we added an option in which a plane drops care packages to waiting hungry villagers instead of bombs on ships or tanks. (The boys still like the bombs best, though - no big surprise!) That therapist also suggested a cause-and-effect display that would result in flowers growing when a cloud rains in the right places, and the Flower Power game option was born. There are lots of other examples, but the point is that we listen to our users and do our best to make Video Voice do what they need it to do.

The goal of this blog is to provide a forum for communicating with our users, as well as people who are considering adding it to their speech therapy tool kits. We’ll tell you about the history, discuss different ways the visual feedback can be used in the therapy process, let you know about new things that we’ve added or are in progress, and answer questions you may have. We welcome your thoughts, opinions, feedback and suggestions.

If you don’t already have Video Voice, you can download the software and try it for free for 30 days to see what benefits it may offer you. Just visit www.videovoice.com and click any of the Free Trial links to get started. By the way, there’s no on going financial obligation with the trial, no credit card necessary to download and try out the games and displays - the trial simply expires at the end of the 30-day period. (You will need an external microphone, and the one we recommend is the Logitech USB Desktop model. It’s a good quality but inexpensive mic that’s commonly used in telecommunications and gaming, and it is easily available at most electronics stores or online, generally for around $30.) If you do already use Video Voice, remember that you can get no-charge updates as new versions are released to keep your software up-to-date.

That’s it for now, and we look forward to more Video Voice Talk with you!
