Abstract

A real-time continuous speech recognition system based on the Inmos transputer is developed. The recognition algorithm is described in detail, and the hardware architecture of the system (which incorporates the AT&T DSP32-C and Inmos T800 transputers) is also described. The implementation of the hidden Markov model recognition algorithm in parallel form is presented. The system has been built using readily available hardware, and it operates using an IBM-PC host, providing real-time speaker-dependent recognition for aircraft movement and spreadsheet control applications
