11.13 Speech Encoding/Decoding
Library
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
speech
for
playback
requires
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.
Key features of the Speech Encoding/Decoding Library
include:
PESQ-based Mean Opinion Score: 3.7-4.2
(out of 5.0)
Code Excited Linear Prediction (CELP) based
coding
2 Analog Input Interfaces – codec or on-chip ADC
2 Analog Output Interfaces – codec or
on-chip PWM
Optional Voice Activity Detection
Storing compressed speech requires 1 KB of
memory per second of speech
Royalty-free (only one-time license fee)
Full compliance with Microchip MPLAB C30
