Abstract:
Systems and methods are provided for speech recognition. The systems and methods are operative to evaluate a spoken word and determine one or more characteristics of a speech waveform corresponding to the spoken word. The speech waveform is converted to a digital pulse waveform based on a threshold level. One or more characteristics of the speech waveform can be analyzed utilizing the digital pulse waveform. The threshold level can be adjustable so that varying voltage amplitudes of speech waveforms can be considered. The one or more characteristics can be matched with one or more stored characteristics to determine the spoken word associated with the speech waveform between a set of selectable words having different waveform characteristics.

Abstract:
A mixed-signal processor (MSP) chip with a flexible serial interface which simultaneously accommodates two serial ports on a reduced number of pins. The pin definitions of these serial ports are configured to function well with several different external chips. Any two of these chips, or two of any one of these chips, may be used concurrently by the present MSP. When used with chips that require it, the present MSP chip provides a clock signal to each of these. When used with other chips, the MSP will can receive a clock signal from an external chip, and will then pass this signal through to any chip on the other of the two serial ports.
