NEC Corporation has developed 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 200 MHz. 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. A few of the features of this software include: A parallel, large-vocabulary, continuous speech recognition engine; a lexical-rule-based, machine translation engine, which achieves high-performance translation of spoken words utilizing dictionaries/grammar, compiled from a wide range of language knowledge data; and an advanced wave-concatenative speech synthesis engine, which realizes high-performance reading through an advanced, wave-concatenative speech synthesis method based on a wide-range of speech data.
