Speech Coding,-PCM, adaptive PCM (APCM), differential PCM (ADPCM), delta modulation (DM), adaptive delta modulation (ADM) and continuously variable slope delta modulation (CVSD). All of these techniques operate directly on the time-domain signal and achieve reduced bit-rates by exploiting the sample-to-sample correlation or redundancy in the speech signal.

ng from speech analysis and speech synthesis through to automatic speech recognition and speech coding. The emphasis is mainly on the signal processing aspects of speech and the treatment is primarily descriptive and illustrative, with the mathematical content being kept to a minimum.

The Nature of Speech,the most natural form of communication between humans, speech is a subject which has attracted much interest and attention over many years. The structure of speech, its production and perception mechanisms have long occupied linguists, psychologists and physiologists. Scientists and engineers have e

Digital Speech,hnology of devices for storing and processing audio signals. Many modem tape-recorders and disk-players use digital rather than analogue techniques. Digital transmission of speech is being used to an increasingly large extent on the Public Services Telephone Network (PSTN), and telecommunication sys

Parametric Speech Analysis,lysis of the speech signal. This chapter describes the basic techniques that are normally used to extract acoustic information directly from the speech signal. Most of these techniques are based on the source-filter model of speech production which was introduced in chapter 1. In this model, the exc

Feature Extraction,l analysis, autocorrelation and linear predictive analysis, were described. In all of these methods, speech is analysed in 10–30 ms time frames and for each frame, a set of parameters or coefficients is derived which either directly or indirectly yields information about the vocal tract and/or its e

Speech Synthesis, sufficiently accurate then the production of intelligible synthetic speech should be possible. There are two basic approaches in modelling the speech production process. One is a direct approach which attempts to model the system in detail. This is commonly referred to as . and attempts to directly
