Abstract :
The design of a toy doll´s speech recognition and response circuitry is summarized. The digital signal processing (DSP) system used as the core of this audio processing circuitry is discussed. Hardware used and the basic DSP architecture for the audio processing are reviewed. Two systems considered (DSP with codec and custom DSP chip) are briefly outlined. The speech processing, synthesis, and recognition technologies needed for this toy are detailed. Several DSP algorithms for use with this system are reviewed.
