27. The non-transitory computer-readable storage medium of claim 26 , wherein the operations further include: receiving a run-time utterance of the input speaker speaking the input language; generating an enriched transcription in the output language of the received run-time input speech signals; speech-adapting the output HMM state models of the chimaera HMM based speech features generator using the determined speech-adaptation transforms to thereby produce a speech-adapted chimaera HMM based speech features generator; using the speech-adapted chimaera HMM based speech features generator to convert the enriched transcription into corresponding output speech features in the output language; and synthesizing a spoken utterance of the enriched transcription in the output language using the output speech features.
