VLSI Implementation of an Voice Gender Converter

Tony’s research is focused on implementation of DSP algorithms into hardware using high level VLSI design. At present Tony is working on a Voice Gender Normalisation algorithm to be implemented into CMOS technology. This will result in changing the gender speech characteristics of a speaker so their speech sounds like a member of the opposite sex, i.e., male to female or female to male conversion. The technology will be used in the area of speech compression for transmission purposes, speech recognition and voice disguise. The algorithm will be implemented in real time to enable use in mobile phones and other communication devices.

Tony’s most recent project was implementing a real time pitch detector into a CMOS technology. This was used in conjunction with an adaptive filter to achieve real time noise cancellation in a speech signal.
