NEC Corporation has 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.

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 for single-chip processors with several CPU cores, and a compact, lexical-rule-based, machine translation engine that unites dictionaries with grammar that is operable on small devices.

The features of this software include: a parallel, large-vocabulary, continuous speech recognition engine, which is built with a database consisting of a wide-range of conversation sounds and words that enables accurate speech recognition of spoken words; a lexical-rule-based, machine translation engine, which achieves high-performance translation of spoken words utilizing dictionaries/grammar, compiled from a range of language knowledge data; an advanced wave-concatenative speech synthesis engine, which realizes high-performance reading through an advanced, wave-concatenative speech synthesis method based on speech data; and an integration module that controls collaborative operation of the speech recognition engine, the machine translation engine, and the speech synthesis engine realizing automatic translation on a single processor for mobile phones.
