Latest Patents

Asada holds a patent for a speech recognition system that utilizes an acoustic signal processing circuit. This system extracts input speech pattern data and subsidiary feature data from an input speech signal. The input speech pattern data comprises frequency spectra, while the subsidiary feature data includes phoneme and acoustic features. These data are stored in a data buffer memory. The system computes similarity measures between the input speech pattern data and reference speech pattern data stored in a dictionary memory. When the largest similarity measure exceeds a first threshold value, the system produces category data corresponding to the input speech. This innovative approach allows for effective recognition of input voice through subsidiary feature recognition.
