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. .
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 (e.g., point to the differences on the screen and discuss). As part of the exercise, users may guide students through repeated attempts to more closely match the waveform. Waveforms can be trimmed using scissors, and slowed down to half or three-quarter speed.
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 Inotation 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.
