VoiceCompress 1.0 SDK

VoiceCompress 1.0 consists of an executable, library, example program, and API.

Fonix VoiceCompress reduces the size of digitally captured speech. Cell phones and MP3 players use compression to minimizes the size of speech and music. Fonix VoiceCompress is optimized for compressing speech signals for applications requiring large amounts of recorded speech with minimal memory and CPU resources.

Fonix VoiceCompress is built on two speech compression technologies: Linear Predictive Coding (LPC) and Code Excited Linear Prediction (CELP). Both are implemented with proprietary algorithms that maximize the speech quality while minimizing memory and CPU requirements. Fonix VoiceCompress provides a low-cost solution for the smallest embedded products to large server installations requiring large amounts of stored recorded data.
