The dsPIC® DSC Speex Speech Encoding/Decoding Library performs toll-quality voice compression and voice decompression. The library is a modified version of the Speex speech coder and is optimized specifically for the dsPIC DSC family of Digital Signal Controllers (DSCs). It uses Code Excited Linear Prediction (CELP), which is a popular coding technique. The library supports both Narrowband and Wideband modes. It samples speech at 8 kHz or 16 kHz and compresses it to a selectable bit rate. The compressed speech data now requires less memory for storage or less bandwidth for communication.
