Speech Processing functions
The Prosody cPCI card is designed for processing digitised speech data, with support for
recording/playback, conferencing, DTMF and call progress tones. Speech and tone data is
transferred in either direction between the host storage medium and any of the channels on the
H.110 CTBus, via the Compact PCI

bus. Four SHARC DSPs on the Prosody cPCI card provide
various processing functions on the data including:
Playback and recording of speech data including
•
Compression and decompression between the H.110, 64kb/s speech data and the host
computer hard drive. Configurable compression rates of 48, 32, 24, 16, 12, 8 kb/s data files
can be encoded/decoded
•
Pitch invariant fast and slow replay (50 to 200%) at all data rates
•
Trimmed recording to eliminate periods of silence at all data rates
