Sona-Match provides a variety of feedback modes. The program includes a vowel chart mode that plots, in real time, the first formant against the second formant to graphically show client utilization of vowel space and neutralization. Target IPA symbols can be left on screen for measurement and biofeedback guidance. The program provides graphic and audio feedback of both the target and client's utterances. Target patterns, available for women, children, and men, are user-alterable.
Users can move and add different vowel symbols to customize the application for each client.
A click of a button adds the appropriate target for the client to match. In the spectrum mode for vowels, an LPC-derived frequency spectrum is plotted in real time with formant values identified. A target can be placed on the screen while user attempts vowels in isolation, or in words, to match the target. Easy to Use Sona-Match is easy to use with complete online Help and easy set up. All of the client's speech attempts are stored for playback so that the client can see and hear critical differences.
