ANGUS: the Highway to Yell

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.

Cracking the social code of speech prosody

New paper out this month in PNAS, in which we use new audio software (CLEESE) to deploy reverse-correlation in the space of speech prosody, and uncover robust and shared mental representations of trustworthiness and dominance in a speaker’s voice.  The paper is open-access, data and analysis code freely available at https://zenodo.org/record/1186278 and the CLEESE software is open-source and available as a free download here.

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.

Voice transformation tool DAVID now available on the IRCAM Forum!

Exciting news! As of March 2017, DAVID, our emotional voice transformation tool, is available as a free download on the IRCAM Forum, the online community of all science and art users of audio software developped in IRCAM. This new plateform will provide updates on the latest releases of the software, and better user support. In addition, we’ll demonstrate the software at the IRCAM Forum days in Paris on March 15-17, 2017. Come say hi! (and sound all very realistically happy/sad/afraid) if you’re around.

Upcoming: Two invited talks on reverse-correlation for high-level auditory cognition

CREAM Lab is hosting a small series of distinguised talks on reverse-correlation this month:

  • Wednesday 22nd March 2017 (11:00) – Prof. Fréderic Gosselin (University of Montreal)
  • Thursday 23rd March 2017 (11:30) – Prof. Peter Neri (Ecole Normale Supérieure, Paris).

These talks are organised in the context of a workshop on reverse-correlation for high-level audio cognition, to be held in IRCAM the same days (on-invitation-only). Both talks are free for all, in IRCAM (1 Place Stravinsky, 75004 Paris). Details (titles, abstract) are below.
