Melodis crystal decoder method and device for searching an utterance by accessing a dictionary divided among multiple parallel processors

摘要

The technology disclosed relates to a system and method for fast, accurate and parallelizable speech search, called Crystal Decoder. It is particularly useful for search applications, as opposed to dictation. It can achieve both speed and accuracy, without sacrificing one for the other. It can search different variations of records in a reference database without a significant increase in elapsed processing time. This is accomplished by first accessing the database, and for each word representation in the database, searching an utterance for likely instances of the word representation utilizing multiple parallel processors. Even the main decoding part can be parallelized as the number of words increase to maintain a fast response time.

主权项

1. A method of electronically processing an utterance to locate candidate words at arbitrary positions within the utterance, including:
accessing a dictionary of word sets each comprising multiple word representations; for each word representation, searching the utterance for likely instances of the word representation and scoring each likely word instance for a probability of a match to the word representation; wherein, the utterance is searched by multiple processors operating on the multiple word sets; and reporting at least a subset of likely word instances and respective probability scores for further electronic processing.
