CONTEXT SENSITIVE MULTI-STAGE SPEECH RECOGNITION

摘要

A system enables devices to recognize and process speech. The system includes a database that retains one or more lexical lists. A speech input detects a verbal utterance and generates a speech signal corresponding to the detected verbal utterance. A processor generates a phonetic representation of the speech signal that is designated a first recognition result. The processor generates variants of the phonetic representation based on context information provided by the phonetic representation. One or more of the variants of the phonetic representation selected by the processor are designated as a second recognition result. The processor matches the second recognition result with stored phonetic representations of one or more of the stored lexical lists.
