| 摘要 |
The present invention provides a system and method for improving conventional, isolated word, speech recognition systems. According to exemplary embodiments of the present invention, a pattern matching algorithm is provided that permits an unknown speech signal to be recognized with fewer memory access operations compared to conventional techniques. The pattern matching algorithm performs multiple successive calculations on speech reference data retrieved from memory to thereby reduce the number of times that the same data is retrieved. By reducing the number of memory access operations, the throughput of the speech recognition system can be increased. As an alternative, the pattern matching algorithm allows for an increase in the size of the speech recognition system's vocabulary.
