First International Conference on Spoken Language Processing (ICSLP 90)
An enhanced version of Transform Coding with a Weighted Vector Quantization (TC-WVQ) speech coder combined with Bit Selective Forward Error Correction (BS-FEC) at 11.2 kbit/s is presented. In this version, speech quality, channel error robustness, computational complexity, and the memory requirements are improved. A real-time operating codec (8.2 MIPS in total) can produce high quality speech in an error free channel. This codec also produces intelligible speech even in a channel of 3% burst error.
