REAL-TIME ADAPTATION OF IN-VEHICLE SPEECH RECOGNITION SYSTEMS |
| 摘要 |
A system and method of controlling an automatic speech recognition (ASR) system includes: detecting changes in ambient noise via a microphone in a vehicle equipped with the ASR system; determining an environmental noise compensation value and a channel bias compensation value based on the detected changes; and applying the environmental noise compensation value and a channel bias compensation value to speech received by the ASR system. |

1. A method of controlling an automatic speech recognition (ASR) system, comprising the steps of:
(a) detecting changes in ambient noise via a microphone in a vehicle equipped with the ASR system; (b) determining an environmental noise compensation value and a channel bias compensation value based on the detected changes using a non-linear transfer function with a weighted smoothing parameter, wherein the weighted smoothing parameter is based on in-vehicle environmental measurements; and (c) applying the environmental noise compensation value and a channel bias compensation value to speech received by the ASR system. |
