Hitachi Ltd says it has developed a new speech recognition technology that combines neuro-computing techniques with fuzzy logic. Speech patterns are identified by the neuro-computer and meaning is discriminated using fuzzy logic. The system is claimed to have understood 95% of a 3,000 word conversation, and picked up correctly 70% of the words that were misidentified by conventional systems based on pattern recognition. Hitachi hopes to have the new technology commercially available within two years, and sees potential markets in the automatic transcription of conference proceedings and for enabling us to hold conversations with computers.
