Method and Apparatus for Identifying Acoustic Background Environments Based on Time and Speed to Enhance Automatic Speech Recognition

摘要

Disclosed are systems, methods, and computer readable media for identifying an acoustic environment of a caller. The method embodiment comprises analyzing acoustic features of a received audio signal from a caller, receiving meta-data information, classifying a background environment of the caller based on the analyzed acoustic features and the meta-data, selecting an acoustic model matched to the classified background environment from a plurality of acoustic models, and performing speech recognition as the received audio signal using the selected acoustic model.

1. A method comprising:
analyzing acoustic features of a received audio signal from a communication device; identifying a repeating pattern of meta-data associated with the acoustic features; classifying a background environment of the caller based on the acoustic features and the repeating pattern of meta-data, to yield a background environment classification; selecting an acoustic model matched to the background environment classification from a plurality of acoustic models; and performing speech recognition on the received audio signal using the acoustic model.
