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; and cause an output device to present an output interpretation according to the second language derived from the second language representation.
