IBM Corp is working on a voice recognition co-processor for personal digital assistants and other embedded devices. The company has a small team working on ways of embedding voice recognition on a chip. Design plans are at an early stage at the moment, and the company is unsure if it will use some kind of DSP architecture or a custom ASIC design. The chip is envisaged as a command and control application – using elements of its ViaVoice speech recognition software. The firm also envisages the possibility of using the chip as a co-processor in desktop PCs to drastically improve speech applications performance, in the same way that graphics accelerators speed 3D graphics rendering – a possibility we first mooted in Computergram last year (CI No 3,449).
