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,

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,

Where's That Vowel?

One of the things Video Voice is helpful with is training production and differentiation of vowel sounds. In fact, in its original, prototype form, with only an F2/F1 display, that’s all it really could do!  The people who developed it were particularly interested in vowel production work, and based the display on Grant Fairbanks’ 1959 Voice and Articulation Drill Book (see History of Video Voice http://videovoicetalk.blogspot.com/2011_03_01_archive.html). 

In the F2/F1 display, vowels map into regions of the screen that generally correspond to place of production in the mouth, where the left side of the screen is the front of the mouth, and the right side, the back. The sample screen below illustrates this with a high front vowel (/i/) and a low back vowel (/a/) map in this display.

Minor changes in articulator position can affect the sounds that are produced, but the ear is ingeniously capable of differentiating, or in some cases, "glossing over" them. The difference between the long and short "E" sounds ("beet" and "bit") is a slight relaxation of the tongue away from the hard palate. These subtle differences can be difficult for speakers of other languages to hear and master, although they make a very real difference to native speakers. The difference in meaning is significant, for example, with something like "sheet metal."

"ih" (as in "bit) and "eh" ("bet") are also similar sounds, although the latter is produced slightly lower and farther back in the mouth. Again, other languages may not have the same set of vowel sounds, so learning to produce and differentiate these sounds can be a challenge. The F2/F1 display can help make these subtle differences more obvious.

The "squiggly" lines that represent these sounds in the F2/F1 display are formed from the speech data  that comprises them. Some of the dots result from the initial onset of sound and trailing off to silence at the end, and those dots are less meaningful than the ones related to the actual sound, which typically appear in clusters in a general area of the screen.

If those you’re working with young children or others who find the standard F2/F1 display difficult to interpret, you can use an alternate way to illustrate sounds - the Spheres Style. This is particularly useful for single-sound targets. Activate this in the F2/F1 display after producing targets by clicking the Style control, and the patterns change from squiggly lines to blue and red spheres which illustrate the greatest density of dots in the pattern. You can then have the speaker try to match the location of vowels that way. (If you want the Style option to be the default display, use the Adjust button to change that control.)

We added this control after talking with a speech professor who was interested in exploring differences between vowel locations with groups of individuals - men vs. women, children vs. adults, native vs. non-native speakers. Pitch differences between speakers do affect the formant frequencies of sounds, and this is another way to show that fact. If you’re interested in more technical aspects of the sounds, you can dwell with your cursor over the spheres to see the F2 and F1 frequency values. (This works with the regular "squiggly" patterns as well.)

Video Voice has lots of options for changing how the displays operate to make them the most useful for people you’re working with. Any adjustable control is highlighted in cyan color, and the cursor also changes to a "hand" graphic to let you know something can be changed, and you’ll also see a "tool tip" that provides a brief description of its function. So have fun, experiment and explore all it can do!

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!

Say YESSSSSS!

Therapists who work with hearing-impaired speakers have often told us that teaching them how to produce /s/ and related high-frequency sounds is a big challenge, as the frequency ranges in which these sounds exist is generally outside the range in which deaf folks can hear.  While it is possible to illustrate production of these sounds somewhat with the lips and air flow from the mouth, it’s really little changes in tongue position behind the teeth that make the most difference, and these can't be easily shown.  Having a concrete way to illustrate the differences between these two sounds can make a real difference in results.  The same is true with children who lisp or lateralize the /s/ sound. 

With Video Voice’s Formant Multi-Frequency displays, there are a couple of ways to make the differences between /s/ and /sh/ visible. One is the Temporal Display, which represents the F3, F2 and F1 components of a production. In that display, if you say a word that contains both /s/ and /sh/ sounds, such as "sunshine," you will see distinct differences in the F3 and F2 frequencies for the two sounds. With the /s/ sound, the F3 frequencies are higher than those for the /sh/, while the F2 levels higher for /sh/ than they are for /s/.

Any speech production can be saved as a model, and used for repeated practice of sound or words.

There’s also a Matrix-Match form of the Multi-Frequency Display. It transforms the F3 and F2 frequencies measured into a relationship of those sound components. This makes sounds like /s/ and /sh/ appear as dense patches of color in different regions of the screen, as shown the sample below.

You can use these matrix patterns in a model match mode, or in a live feedback format similar to the F2/F1 Gobble game. The immediate visual response to sound changes in the Gobble mode helps speakers learn articulator position needed to produce these sounds accurately.

There is presently no scoring in the Formant Multi-Frequency displays, but we’re working on that, and expect it to be available in an upcoming release. Stay tuned!

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.
