Analysis of On-Off Characteristics of Bangla Speech Over Telephone Channel

Abstract

Speech interpolation technique is used in present day communication to ensure maximum utilization of the available communication channels. The measurement and modelling of on-off speech characteristics are essential for the design and performance analysis of speech interpolation systems. This paper presents the on-off characteristics of conversational Bangla speech over a telephone channel, using a large database. Proper mathematical models are also developed for them.

Indexing terms:

• Speech interpolation
