Mobile speech-to-speech interpretation system

摘要

Interpretation from a first language to a second language via one or more communication devices is performed through a communication network (e.g. phone network or the internet) using a server for performing recognition and interpretation tasks, comprising the steps of: receiving an input speech utterance in a first language on a first mobile communication device; conditioning said input speech utterance; first transmitting said conditioned input speech utterance to a server; recognizing said first transmitted speech utterance to generate one or more recognition results; interpreting said recognition results to generate one or more interpretation results in an interlingua; mapping the interlingua to a second language in a first selected format; second transmitting said interpretation results in the first selected format to a second mobile communication device; and presenting said interpretation results in a second selected format on said second communication device.

主权项

1. A communication device comprising:
a language input device configured to detect a first language signal associated with a first language; and a recognition and interpretation engine coupled with the language input device and configured to:
obtain the first language signal from the language input device;generate a first recognition result set from the first language signal according to at least one of a grammar and statistical language model of the first language, said language model comprising a mobile interference model;generate an improved recognition result set from the first recognition result set by rescoring the first recognition result set according to a domain-specific language model;generate at least one interpretation result from the improved recognition results set;map the at least one interpretation result to a second language representation of a second language; andcause an output device to present an output interpretation according to the second language derived from the second language representation.
