NEC Develops Speech-to-Speech Translation Software 

NEC Develops Speech-to-Speech Translation Software for Low Power
Consumption Multi-Core Processors Optimal for Small Devices such as Mobile


Tokyo, October 24, 2005 --- NEC Corporation today announced that it has succeeded in the development of Japanese-English/English-Japanese, automatic speech translation software for single-chip multi-core processors for small devices such as mobile phones, capable of operation at high speeds with low power consumption. NEC verified the high-speed automatic speech translation processing capability of this software on NEC Electronics' MP211 (

) application processor for mobile phones, at an operating frequency of 200MHz, proving that operation of interpretation applications is technologically feasible on small devices like mobile phones.

Supporting a 50,000-word rich vocabulary, this software realizes automatic speech-to-speech interpretation of travel conversation through the development of a new parallel speech recognition method (
