Spoken Language Understanding


Spoken language understanding is the task of assigning a semantic interpretation to a spoken input, by making use of syntactic and semantic knowledge, which is often specific to a particular application domain. Spoken language understanding can involve dealing with multiple recognition hypotheses from a speech recogniser, taking prosodic properties of utterances into account and having to deal with fragmentary and grammatically incorrect utterances. Commercial speech recognisers often are accompanied by analysis tools. In commercial applications such as dialogue systems and command and control, spoken language understanding generally involves the construction of a task and domain-specific interpretation of the utterance.
