dsPIC30F Speech Encoding/Decoding Library
The dsPIC30F Speech Encoding/Decoding Library
performs toll-quality voice compression and voice
decompression. The library is based on a modified
version of Speex source code and features a 16:1
compression ratio. It samples speech at 8 kHz and
compresses it to a rate of 8 kbps. Storing compressed
speech for playback requires approximately 1 Kbyte of
memory for each second of speech.
Features
Key features of the library include:
? Fixed 8 kHz sample rate
? Fixed 8 kbps output rate
? PESQ-based Mean Opinion Score: 3.7-4.2 (out of 5.0)
? Code Excited Linear Prediction (CELP)-based coding
? Two analog input interfaces – codec or on-chip
12-bit ADC
? Two analog output interfaces – codec or
on-chip PWM
? Optional Voice Activity Detection
? Playback-only applications will benefit from the
Speech Encoder Utility. It allows you to make
encoded speech files from your desktop using a PC
microphone or WAV file
? Storing compressed speech requires 1 KB of
memory per second of speech
? Off-chip support for playback of long speech samples
? Royalty free (only one-time license fee)
? Full compliance with Microchip MPLAB ? C30
C Compiler Tools
? “dsPIC30F Speech Encoding/Decoding Library
User ’s Guide” (DS70154) is provided to help the user
understand and use the library
? Designed to run on dsPICDEM? 1.1 Demonstration
