| 发明名称 | System and method to reduce transmission bandwidth via improved discontinuous transmission | ||
| 摘要 | The present disclosure is directed towards a method for discontinuous transmission (“DTX”) bandwidth reduction. The method may include receiving, at a processor, a frame identified as speech and determining that the frame was mistakenly identified as speech based upon, at least in part, a voice activity detection algorithm. The method may further include labeling the frame as a silence indicator frame. | ||

| 主权项 | 1. A method for discontinuous transmission (“DTX”) bandwidth reduction comprising: receiving, at a processor, a frame having an audio signal identified as speech included therein; determining that the frame was mistakenly identified as speech based upon, at least in part, a voice activity detection algorithm; in response to determining that the frame was mistakenly identified as speech, labeling the frame as a silence indicator frame; and bypassing an intended voice quality assurance processing operation based upon, at least in part, the determination. | ||
