SPEECH ANALYSER BASED ON THE IBM PERSONAL COMPUTER.

Abstract

The Speech Analyser (SAY) is intended for a diverse set of users engaged in the evaluation of natural and synthetic speech. The SAY system consists of a 640 Kbyte IBM PC-XT with 20 Mbyte hard disk, 370 host connection together with special-purpose digitisation and display hardware. Speech may be recorded and replayed from the hard disk at sampling rates up to 40 KHz. A vector display capable of showing two waveforms of up to 1024 points each is provided, together with waveform scrolling and editing facilities. SAY provides a wide range of sophisticated signal processing facilities via a host link to the IBM UKSC IAX image processing package. These facilities include spectral and cepstral analysis, grey scale and colour spectrogram display, LPC analysis and pitch contour extraction.
