Frame erasure concealment technique for a bitstream-based feature extractor |
摘要 |
A frame erasure concealment technique for a bitstream-based feature extractor in a speech recognition system particularly suited for use in a wireless communication system operates to "delete" each frame in which an erasure is declared. The deletions thus reduce the length of the observation sequence, but have been found to provide for sufficient speech recognition based on both single word and "string" tests of the deletion technique.
