Migrating speech files

The Avaya IR platform supports only the G.711 protocol for speech files. To support this, the migration process converts currently supported speech formats on CONVERSANT platforms to PCM64 which follows the G.711 protocol. The G.711 protocol is the international standard for encoding telephone audio on a 64 kbps channel. It is an ITU-T compliant, pulse code modulation (PCM) scheme operating at a 8 kHz sample rate, with 8 bits per sample.

Avaya pre-recorded speech packages have been converted and ported into the Avaya IR base software. They are not part of the migration process.

To migrate speech files to the Avaya IR platform:

1. Ensure that the source ADPCM speech files are placed on a CONVERSANT system.
2. On the CONVERSANT system, run

/mtce/bin/vis2wav -l �e 16 1036 1036.wav

Where /mtce/bin/vis2wav is a standard utility found on all V8 systems, 1036 is the source ADPCM CONVERSANT speech file, and 1036.wav is an intermediate file created as output from the vis2wav.

3. Transfer or ftp the intermediate 1036.wav file to the new Avaya IR platform that is loaded with NMS software and utilities.
4. On the Avaya IR platform, run

vcecopy 1036.wav temp.wav -c10

Where 1036.wav is the intermediate file generated on the V8 platform, temp.wav is output from the vcecopy command and is in final G.711 format suitable for the Avaya IR system.

Note:
The vcecopy command keys off the .wav extensions so make sure to include this file extension.

5. Remove the .wav extension from the file name and rename the file back to its original name or a new name.
