Synthesizer software for modeling voice quality
Norma Antoñanzas-Barroso, Bruce R. Gerratt, Jody E. Kreiman · The Journal of the Acoustical Society of America · 2005
This poster presents a formant synthesizer that is designed especially for detailed modeling of voice quality. Users may interactively manipulate source pulse shapes and/or spectral characteristics of the voice source, the noise spectrum and noise-to-signal ratio, jitter and shimmer, vocal tremor rate and extent, and the vocal tract transfer function (formants and bandwidths), all in near-real time. Pitch contours can be modeled directly or imported. The synthesizer may be utilized in method-of-adjustment tasks, or sequences of stimuli may be created for use in other experimental paradigms. An interactive audio-visual display makes this a useful tool for teaching voice acoustics as well. Both an executable version of the program and the underlying code will be available during the conference. Copies of software that supports the voice modeling effort, including an interactive inverse filter, will also be distributed. [Work supported by NIDCD grant DC01797.]
