SpeechPrompts™ provides speech therapy exercises to help those with autism practice rate, rhythm, stress and loudness of speech (prosody). The U.S. Department of Education’s IES SBIR program funds research and development of SpeechPrompts, a collaborative project with the Yale Child Study Center.

SpeechPrompts is a new app from HandHold Adaptive®, makers of iPrompts®, StoryMaker™ and other leading tools serving those with special needs and their caregivers. It is designed for use with individuals exhibiting abnormal prosody, such as those with autism spectrum disorders (ASDs), Down syndrome and stroke victims. Prosody refers to the musical aspects of speech, including rate, rhythm, volume, phrasing and intonation.

The app includes the following features:

* VOICECHART: Like a “voice thermometer,” VoiceChart provides real-time feedback on loudness of speech. Speakers are shown visually whether they are “Too Loud,” “Too Quiet,” or “Just Right”. Sliders allow customization of the thresholds between each volume zone. An animated meter changes color based on the current volume level. Users may select from included graphics to illustrate when speakers are “Too Loud,” “Too Quiet,” and “Just Right,” or use the built-in camera to supply their own accompanying visuals. VoiceChart can also be useful exercise for individuals with hardness of hearing.

* VOICEMATCH: Provides visual and aural feedback on stress, rate and rhythm of speech by comparing a “Teacher” voice recording to a “Student” voice recording. The Student voice sample is compared both visually (via a waveform graphic) and aurally (via audio playback) to the Teacher recording, which serves as a target or model phrase. The Student attempts to “match” the Teacher waveform by repeating it aloud. Visual differences between the two audio recordings can then be highlighted and compared.

* LIBRARY: Select from 50 included Teacher waveforms, or add your own recording to the Library for later use in VoiceMatch. Search or browse the Library to find existing clips. Users may also categorize, label and re-record samples if desired.

* FLEXIBLE IN DIFFERENT ENVIRONMENTS: A Sensitivity control allows VoiceChart to be used in quiet and loud spaces alike.

* SHOW HOW INTONATION AFFECTS MEANING: Record multiple variations of a phrase, each emphasizing different words (e.g., “Do *you* have that video game?” versus “Do you have *that* video game?”). Then, use these recordings in VoiceMatch to teach how emphasizing different words can change the meaning of a phrase.

* PRODUCT RESEARCH: SpeechPrompts has been investigated in U.S. classrooms by autism researchers from the Yale Child Study Center. Inquiries about our research may be directed to

I downloaded this app for my son with autism. I was excited to see that there was an app that had been created for prosody. Unfortunately I found this app disappointing. The voice match portion of the app does not provide a very useful visual that allows the person to try to change their tone or pitch. It would be more helpful if it graphed pitch or tone so that the student could see how to change their voice. The visual currently only let's the student know if they matched or not. It doesn't show them visually HOW to change it.
The portion of the app for volume works fine, but most of the rest if this app seems to be a waste.
Most of the buttons in this app do nothing.

So I am still in search for a great app to help with monotone language

Been looking for something like this!

Before this, there wasn't a lot out there (other than junk!) for SLPs who work with kids that have autism, or anyone with prosody issues. This app is NOT junk, in fact it is VERY NICE! The voice chart is great for working on volume and you can use different pictures. The voice match tool is perfect for showing subtle differences in speech. Great for visual thinkers that need feedback on stress in speech and voice volume.
