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.

Yours in good speech,

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!

Picture Perfect Speech

There are many aspects of Video Voice that can be adapted to meet the individual needs of the people you work with. You can specify the kinds of reward images and sounds that you want to see and hear. You can choose how scores appear in the Formant and P-A-R displays, as well as some aspects of their calculation. In the games, you can control which reward sounds are played at the end of the game, default Fade Speed, Pitch Range and other aspects of score display and game operation.  Changes you make can be stored as part of your Therapist ID settings , or, if you have a individual’s data folder active, settings can be permanently saved there.  Then, any time you reactivate that person’s data folder, the individualized settings  are automatically used.

The game that has the most options for customization is Voice-A-Sketch.  In that game, meeting the defined speech goal results in a picture appearing, either in pieces or in "window shade" fashion.  (The goals can be continuous phonation, volume above or below a defined target level, production of a target sound or work, and more.)  There are 78 high-quality built-in pictures to choose from, but you can also use images you have stored on your computer.

A few years ago, a therapist who works with autistic children said she felt they would respond more favorably if familiar images appeared - family members, pets or other objects of particular interest to them.  We responded by adding a new Graphics Source control that lets you use either the Built-In or My Own Pictures.  If you choose the latter, Video Voice looks in the My Documents/My Pictures area of your computer, and lets you choose from any images you have stored there.

This provides some very powerful personalization of the game. Say you’ve got a little girl who is very motivated by horses, or a little boy who loves sports cars. You can set up folders under their names in your My Pictures area and fill them with those kinds of images.

There are literally thousands of pictures available online of nearly any image type. Google or other search engines can assist you in locating them. When you find one you want to use, simply right-click on it and use the "Save Image As" option to put a copy of the .jpg or .gif in the desired My Pictures folder.  Voila!  You’ve now got a picture you can use in Voice-A-Sketch.

When importing pictures into Voice-A-Sketch, you don’t have to worry about the shape and size. Video Voice will size the pictures to best fit within the available space and adapt the picture frame accordingly.  The best images will be landscape in orientation, because that’s how the screen’s "easel space" is laid out, but any size or shape will work.

The possibilities are endless!  Have fun personalizing Voice-A-Sketch to make it even more uniquely motivating for individual cases.  If it’s an option for you, you even can involve them in the search for pictures they’d like to see, and use that as a therapy activity, too.

Yours in good speech,

Learning Video Voice - Help Me Choose

Learning to use a new piece of software can be fun, but can also be a challenge. Everything is new and unfamiliar, and you may not be sure where to start. There are lots of choices, and you're not sure what they do. How do you proceed? Click and guess? That's what a lot of us do, and it can be all too easy to get into "deep water," unsure of how you got there and how to get out!

Video Voice is a robust therapy tool with a variety of games and displays, each with many adjustable options that let you tailor operation to your specific needs. We’ve tried to do our very best to make it easy to learn and use. But, because there’s so much you can do with it, figuring out where to start can be daunting.

Welcome to Help Me Choose! In the lower area of the Main and Start-Up menus, you’ll find a Help Me Choose button. This opens an interactive application that lets you pick and choose among many common goals therapists share, things like articulation, vocal awareness, pitch, volume, and breath control and get information about them and access to them.

Start by clicking one of the speech goals. The first one, Vocal Awareness, has been preselected for you, and on the right side of the window you’ll see the different options Video Voice offers for work on that aspect of speech. Click on any of the options, and a brief summary of that game or display appears in the lower area of the window. Want to give it a try? Just click Use, and Video Voice will take you to that area so you can explore it. When you’re done, click Back, and you’ll see the Help Me Choose interactive guide again, where you can select other games or displays to try out.

 Pretty cool, isn’t it? Help Me Choose is just one of the ways Video Voice helps you learn about how it operates. Others include:

• Context-Sensitive Help. You can click Help at most any point in Video Voice operation, and open the extensive internal manual to the page appropriate for the area where you’re working.
• Tool Tips:  Dwell with your cursor over any button or adjustable control (cyan-colored text identifies adjustability), and a little pop-up box will appear that briefly describes its function.
• Start-Up Tips:  This button on the Main Menu provides suggestions on how to get started with Video Voice, as well as access to lots of other information, such as FAQs, Uses and more.
• Solutions and Support PDFs:  Solutions are 1-2 page documents that offer guidance on using Video Voice for common speech goals, things like Vocal Awareness, Articulation, Pitch and Volume.  You can print them to keep handy for reference.  Other support PDFs provide information about Getting Started, and Overview of operation, a handy Displays and Activities reference chart, and more. 

And, if you get stuck, we’re available by phone or email to make suggestions on use for different therapy activities and help you get going. We want your experience with Video Voice to be positive, so don’t hesitate to call on us for assistance!

R-D-R-R-R: Gobbling Up Sounds

Almost every therapist who works with children has at least one with this problem - the pesky R sound. This semi-vowel is one of the most difficult to train, because, unlike many other sounds, it can’t easily be illustrated in the mouth. Minor changes in tongue position and "bunching" are the difference between a nice, clear ‘r’ and a sloppy ‘w’ sound, and lots of kids struggle with that.

Video Voice has a number of ways to help them learn how to produce this sound correctly, but for today, we’ll just talk about one of them, the F2/F1 Gobble display. In this Pac-Man-style game, the speaker uses his voice to erase the dots on the screen. The live feedback is very powerful. It lets him "play" with his voice and get instantaneous response while he explores different articulator positions. Being able to find and maintain correct articular position helps ingrain the kinesthetics of production of this sound.

Here’s a simple way to get going. Use the Formant Menu’s Free Form F2/F1 Match mode and produce a sample of the R target in isolation. We always recommend that you do several trials of a sound, looking for consistency in density and location of the dots before defining one as the model. Once you’ve decided to Use one, click the Match Mode control to switch to the Gobble format. Video Voice will prompt "Say ‘rrrr’" using your voice target, and you can have the child try to Gobble it up. If it’s too easy to succeed, just raise the Goal (percent erasure required to win above the default 80%).

Want to get rid of all the other vowels, leaving only the R symbol ? Just double-click on that symbol, and all the others will magically disappear. 

But what if you’d like to get rid of everything except the R and U, so the child can see the similar location of the two sounds on the screen (and in the mouth!). That’s easy, too. Click on one of the vowels, and when the small instructional box appears, click and drag any unwanted symbols off the edge of the screen. Then click Apply to temporarily save that more limited vowel chart for use in the current session. (Using Save will erase the other symbols until you reactivate them all with the Adjust button, so you may not want to take that more permanent action.)

Then, play, play, play! You’ll be amazed at how long the children will stay on task, how entertained and motivated they’ll be as they gobble up the sound dots.

By the way, if you have used New Session to activate a data folder, you can Save any Free Form target for reuse in subsequent sessions, so you won’t have to go through the definition process each time. Just use the Stored Models option from the Formant Menu to retrieve them later on.

This example presents work on the R in isolation, but you can just as easily set up word targets to let the child practice vocabulary words containing the R sound using these same steps.

That’s it for today! We’ll be back later to tell you more ways to use Video Voice for work on R and other sounds.

Technical Yada-Yada

From time to time, people ask about the technical details of Video Voice. So I asked the programming staff to provide some, and here’s what they had to say.

The heart of the Video Voice software is a specially developed Fast Fourier Transform (FFT) routine packaged in a .dll. It "pumps" the speech data to the various therapy displays and games. The FFT analyzes data obtained from the computer’s sound card and extracts F1, F2, F3, Pitch and Volume data as well as the strength of each frequency in the range of (70-7000 Hz), while simultaneously allowing graphic display and analysis in real-time. The FFT was developed for Version 3.0 and replaces a patented filtering process that required external Speech Analyzer hardware in previous versions of the software. The .dll also contains a set of precision timers that permits timed operations on computers with different internal processor speeds. The ability to use the computer’s sound facilities to record and play back sound files is another capability.

The Video Voice program consists of 270,000+ lines of VB6 programming code organized in more than 5,700 procedures. If printed as a book (called a listing in the old days), it would be over 7,200 pages long. Needless to say, we never print listings any more! In addition to the program code, there are nearly 1,000 built-in picture and sound (.wav) files, and an extensive Help subsystem with more than 150 topics that document program operation and use.

Have your eyes glazed over yet?

So, what does all this mean to Video Voice users? Well, there are 31 different colorful, motivating games and displays with more than 70 different modes of operation that can easily be customized to your personal needs. Most have entertaining graphic animations to reward successful performance. Individuals’ vocal productions are recorded and can be saved as models for repeated use. For most games and displays, performance can be reviewed in a variety of single session and cross-time reports and graphs. Whether your computer is an old workhorse with Windows 2000 or a fancy new one driven by Windows 7, Video Voice will run on it.

The program is fully documented with context-sensitive Help – just click the Help button at any time, and the internal manual will open to the page appropriate for the area where you’re working. There’s also a "Help Me Choose" interactive guide that helps you select appropriate areas for most common speech goals, as well as integrated Demos that use prerecorded audio to simulate operation of the games and displays. Adjustable options and game controls have "tool tips," helpful little hints that pop up to let you know what their basic functions are when you pause your cursor over them. Also integrated are a number of printable PDF supporting materials that suggest activities for work on pitch, volume, articulation and more.

First released in 2006, Version 3.0 is still undergoing development. We continue to find new things to add and ways to enhance what it can do. But more on that later!

Good speech to you,

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/!
