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 based on a previously recorded time and speed of the caller, 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, wherein the repeating pattern of meta-data comprises a speed of a caller associated with the communication device; 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. |
