Kane Computing Offers 8000 bps ICELP Speech Compression Vocoder

3/13/2003 - Kane Computing Ltd can now offer for licensing an Improved Code-Excited Linear Prediction (ICELP) vocoder for speech compression at 8000 bps.

The 8000 bps vocoder, from Spirit Corp., is a proprietary speech compression algorithm based on the well-known CELP model and strongly optimised, ensuring significant improvement of speech quality at low computational complexity.

This algorithm is extremely useful in a wide range of storage capacity and/or bandwidth sensitive applications such as multimedia devices, visual telephony, wireless telephony, secure telephony, and videoconferencing products.

The many features of the 8000 bps ICELP vocoder include; high speech quality (MOS about 4.0), automatic built-in Frame Synchronisation and Comfort Noise Generation (CNG) and directly interfaces with PCM 8 KHz sampled data. The code is re-entrant, supports multithreading and dynamic memory allocation. The vocoder has a very simple application interface and can be easily ported to any DSP or RISC platform.

While claiming extreme cost effectiveness due to its proprietary nature the solution satisfies system requirements comparable with the ITU-T G.729 standard.

The 8000 bps ICELP vocoder is available in the form of object codes for TI's TMS320C54x, C55x (coming soon) and also as a DLL for MS Windows.
