Abstract:

The paper describes a procedure, and its hardware implementation, for the extraction of significant parameters of speech. The process involves division of the speech spectrum into convenient frequency bands, and calculation of amplitude and zero-crossing parameters in each of these bands every 10 ms. In the software implementation, a smoothing function divides the speech spectrum into two frequency bands above and below 1000 Hz. In the hardware implementation, the spectrum is divided into three bands using bandpass filters 150-900 Hz, 900-2200 Hz, 2200-5000 Hz. Details of the design and implementation of the hardware device are given. Author
