Software in Speech, Hearing and Phonetic Sciences

Spectral rotation
A suite of Matlab scripts that perform spectral rotation, of the kind described by Blesser B (1972) Speech perception under conditions of spectral transformation: I. Phonetic characteristics. J Sp & Hear Res, 15: 5-41. For a study that has used this technique, and for examples, follow this link. The software is available here free of charge but with no guarantees and copyright retained by UCL.

ProSynth Project Deliverables
ProSynth was a research project looking at "all-Prosodic" speech synthesis. A number of data and software deliverables are available.

FIX - Feature Information Xfer
FIX (Feature Information Xfer) is a set of programs designed to facilitate analysis of confusion matrices by both ordinary and sequential information transfer analysis (SINFA - Wang & Bilger, 1973, JASA, 54[5] 1248-1266). The programs may be menu-driven, or run as stand-alone modules. These executables run under MS-DOS on an IBM PC or clone. The programs have also been used under UNIX on a MASSCOMP 5/6000 series computer. Source code may be made available for users with special needs. The software is available here free of charge but with copyright retained by UCL.

POLYFIT - Polynomial Fitting of auditory filter shapes
POLYFIT is a program for the fitting of roex filter shapes to thresholds measured in notched noise, especially as a function of level. This software implements the procedures described in a series of publications, most recently: Rosen, S., Baker, R. J., & Darling, A. M. (1998) "Auditory filter nonlinearity at 2 kHz in normal hearing listeners," J. Acoust. Soc. Am. 103, 2539-2550. These executables run under MS-DOS on an IBM PC or clone. They are written in ANSI C and source code may be made available for users with special requirements. The software is available here free of charge but with copyright retained by UCL.
