Abstract
An apparatus and method for automatic continuous-speech recognition is disclosed. The recognition function for a speaker-dependent continuous-speech recognition (CSR) system is performed on a (PCMCIA) card, which includes a DSP, Codec, and memory. All of the processing performed by the CPU, DSP, and special DTW chip in prior art systems are performed in the single DSP on the PCMCIA card. Recognition results computed on the card are uploaded to the host computer application (for command interpretation and processing), via the PCMCIA interface. The host computer may comprise a personal computer, making this invention particularly well-suited for use in military or other such operations which require light-weight portable computers.
