Problems solved by technology

It is challenging and difficult to develop speech recognition systems that provide users with the perception of high accuracy and fast response time
Using a large vocabulary leads to slower speech recognition response times
Traditional speech recognition systems attempt to speed up perceived response times by prompting the user for discrete pieces of a command or task (e.g., "which state?", "which city?", etc.)

Embodiment Construction

[0013] Referring generally to the drawings, a voice recognition system for a vehicle is shown according to an exemplary embodiment. The speech recognition system is able to combine received utterances (e.g., data representing utterances) with a selected small set of grammars (e.g., voice commands, names, voice tags, favorite places, etc.) in a first pass of speech recognition. , favorite contacts, etc.) to provide faster speech recognition. If the first pass is successful, the perceived speed of the system is very fast. If the first pass is unsuccessful, the system will use a larger set (or complete set) of possible grammars (eg, a complete address book, a complete phone book, a complete list of commands, etc.) for a second pass.

[0014] In an exemplary embodiment, a speech recognition system for a vehicle includes a microphone for receiving speech from a user. The system also includes a memory having a partial set of commands or names for speech recognition. The memory al...

Abstract

A speech recognition system for a vehicle includes a microphone for receiving speech from a user. The system also includes a memory having a partial set of commands or names for speech recognition. The memory also includes a larger set of commands or names for speech recognition. The system also includes processing electronics in communication with the microphone and the memory. The processing electronics are configured to process the received utterances to obtain utterance data. The processing electronics are further configured to use the obtained speech data for at least two passes of speech recognition. In the first pass, the utterance data is compared to the partial collection. In a second pass, the utterance data is compared to a larger set.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit and priority of U.S. Provisional Patent Application No. 61 / 663,423, filed June 22, 2012, entitled "Multi-pass Vehicle Voice Recognition Systems and Methods," the disclosure of which is incorporated by reference in its entirety This article. Background technique [0003] The present invention relates generally to the field of vehicle-based speech recognition systems and methods. [0004] Some speech recognition systems attempt to recognize large numbers of words, phrases or names. It is challenging and difficult to develop a speech recognition system that provides users with a perception of high accuracy and fast response time. Using a large vocabulary results in slower speech recognition response times. Traditional speech recognition systems attempt to speed up perceived response times by prompting the user for discrete pieces of a command or task (eg, "which state?", "which city?",...
