ANGUS is a real-time voice transformation tool able to simulate cues of arousal/roughness on arbitrary voice signals with a high degree of realism. Vocal roughness is generated by highly unstable modes of vibration in the vocal folds and tract, which result in sub-harmonics and nonlinear components which are not present in standard phonation. We propose to simulate this physiological mechanism using multiple amplitude modulations driven by the fundamental frequency of the incoming sound.

Ministry of Silly Talks: Infinite numbers of prosodic variations with C.L.E.E.S.E.
C.L.E.E.S.E. (Combinatorial Expressive Speech Engine) is a tool designed to generate an infinite number of natural-sounding, expressive variations around an original speech recording. More precisely, C.L.E.E.S.E. creates random fluctuations around the file’s original contour of pitch, loudness, timbre and speed (i.e. roughly defined, its prosody). One of its applications is the generation of very many random voice stimuli for reverse correlation experiments, or whatever else you fancy, really.
