11.13 Speech Encoding/Decoding
The Speech Encoding/Decoding Library performs toll-
quality voice compression and voice decompression.
The library is based on a modified version of the Speex
speech encoder/decoder source code and features a
16:1 compression ratio. It samples speech at 8 kHz and
compresses it to a data rate of 8 kbps. Storing
compressed
approximately 1 KB of memory for each second of
speech. The library is especially suitable for the
following voice-based applications:
• Answering Machines
• Building and Home Safety Systems
• Intercoms
• Smart Appliances
• Voice Recorders
• Walkie-Talkies
• Any Application using Message Playback
A PC-based speech encoder utility program allows you
to create your own encoded speech files for playback.
Encoded speech files are made from either a PC
microphone or existing WAV file. Once you create the
encoded speech files, they are added to your MPLAB
C30 project, just like a regular source file, and built into
your application. The speech encoder utility allows you to
select four target memory areas to store your speech file:
program Flash memory, RAM and external Flash
memory. External Flash memory allows you to store
many minutes of speech (1 minute of speech requires
60 KB) and it is supported through a general purpose I/O
port.
