speech and signal processor circuit card (CWB1)
A high-performance signal processing circuit card capable of simultaneous support
for various speech technologies.
speech energy
The amount of energy in an audio signal. Literally translated, it is the output level of
the sound in every phonetic utterance.
speech envelope
The linear representation of voltage on a line. It reflects the sound wave amplitude at
different intervals of time. This envelope can be plotted on a graph to represent the
oscillation of an audio signal between the positive and negative extremes.
speech file
A file containing an encoded speech phrase.
speech filesystem
A collection of several talkfiles. The filesystem is organized into 16-Kbyte blocks for
efficient management and retrieval of talkfiles.
