The dsPIC30F Speech Encoding/Decoding Library from Microchip Technology is a high-quality and cost-effective means of performing compression and decompression of speech signals. This is useful in two ways: either to reduce the storage requirements of an application that involves storage of recorded speech messages, or to reduce the communication requirements of systems that involve speech communications over a bandwidth-limited communication medium (eg, walkie-talkies).
The compression algorithm used by the library is based on a modified open-source speech encoding/decoding technology called Speex, and is therefore a more economical option for customers compared to speech coders that require payment of significant royalties. The library features a 16:1 compression ratio and an 8 Kbps data rate, making the library a good choice for digital voice communication, store-and-playback and playback-only applications. For playback-only applications, a PC software utility is included, allowing the designer to create encoded speech files for playback.
