The Track-Draw package provides three complementary features. First, it provides a simple graphical technique for entering a set of parameter vectors (tracks) that serve as input to the synthesizer. Second, it has a copy synthesis procedure which enables the user to draw a set of formant tracks over the spectrogram of a recorded speech sample, synthesize the pattern, and compare the synthesized version to the original. Third, it includes a sine-wave synthesis procedure which replaces the time-varying formant pattern of natural speech with a set of frequency-modulated sinusoids (Remez, Rubin, Pisoni, & Carrell, 1981).
Track Draw was created by the collective efforts of Peter Assmann, Will Ballard, Laurie Bornstein and Dwayne Paschall. Send us an email message if you have comments, questions, or suggestions: [email protected].
