| Research Abstract |
In order to realize a high performance speech recognition system, techniques to refer large amounts of knowledge base in real time should be developed. In the actual application areas of speech recognition, not only high recognition rate but low cost is strongly requested. Considering both requirements, this research aimed to study a parallel processing architecture suitable for the speech recognition and LSI architecture design system which particularly intended to produce digital signal processing LSIs. As for the parallel processing, a special experimental system was developed as a multiprocessor system composed of Transputers which are special microcomputers with communication links. Many kinds of pattern matching processes in speech recognition can be performed concurrently by exchanging intermediate matching. The system is tested by the task of parge vocabulary words recognition. It was verified that the parallel processing could effectively combine several kinds of paradigms developed for the word recognition.
The second objective of this research is to construct an architecture design system for LSIs. The input to this system is a specification description on the required function which is described by special high level specification language and the output is the hardware description at the register transfer level. LSIs can be produced from these decription by using the conventional CAD system. This study sdhowed a new possibility applying artificial intelligence technique to design problems.
