Abstract
Speech recognition systems often process speech by employing models and analyzing audio data. An embodiment of the method and corresponding system described herein allow for passive monitoring of for example, conversation between user(s) to determine context to use to prime model(s) for later speech recognition requests submitted to the speech recognition system. The embodiment improves the results of the speech recognition system by updating speech recognition model(s) with contextual information of the conversation. This increases the probability that the speech recognition system interprets the conversation to contextually relevant information.
Claims19
A method comprising:
- extracting contextual information from a conversation by performing speech recognition passively in the background while a speech recognition system is inactive from executing a speech recognition request from a user;
- and
- applying the contextual information to the speech recognition system to enhance analyzing speech directed to the speech recognition system.
A system comprising:
- an extraction module configured to extract contextual information from a conversation by performing speech recognition passively in a background while a speech recognition system is inactive from executing a speech recognition request from a user;
- and
- an enhancement module configured to apply the contextual information to the speech recognition system to enhance analyzing speech directed to the speech recognition system.
A computer program product comprising non-transitory computer readable medium storing instructions for performing a method, the method comprising:
- extracting contextual information from a conversation by performing speech recognition passively in the background while a speech recognition system is inactive from executing a speech recognition request from a user;
- and
- applying the contextual information to the speech recognition system to enhance analyzing speech directed to the speech recognition system.
