1. A method of context adaptation of a speech-to-speech translation system comprising the steps of: extracting a plurality of sets of paralinguistic attribute values from a plurality of input signals, wherein each set of the plurality of sets of paralinguistic attribute values is extracted from a corresponding input signal of the plurality of input signals via a corresponding classifier of a plurality of classifiers; generating a final set of paralinguistic attribute values for the plurality of input signals from the plurality of sets of paralinguistic attribute values; and modifying performance of at least one of a speech recognition module, a translation module and a text-to-speech module of the speech-to-speech translation system in accordance with the final set of paralinguistic attribute values for the plurality of input signals.
