USAGE OF SPEAKER AS MICROPHONE FOR SOUND ENHANCEMENT |
摘要 |
<p>The method and system use a speaker available in an audio end device when not in use as a microphone. The speaker is utilized for enhancing the sound quality received by the person or device at the near end, i.e., the user of the device, or the speaker at the far end, i.e., the speaker with whom the near-end speaker is communicating. Exemplary applications are shown for such utilization, including single or dual microphone near-end automatic listening enhancement, acoustic echo cancellation or suppression with or without double talk detection, and microphone array noise reduction.</p> |
