基于运动的语音活动检测
摘要：
本发明涉及基于运动的语音活动检测。在常规的系统中，单独地基于诸如零交叉或能级的音频流的特性或特征来计算语音检测系统的输入。本发明涉及基于各种输入来判定接收音频流的系统是否应处于语音或非语音这两种状态之一的判定规则。除音频流以外，判定规则可结合基于运动的流作为判定规则的输入。权利要求书针对接收数据流，确定与数据流相关联的至少一个非音频元素是否指示该数据流包括语音，并且，响应于确定与数据流相关联的至少一个非音频元素指示该数据流包括语音，对与该数据流相关联的至少一个音频元素执行语音到文本转换。
摘要（英）：

Motion-based voice activity detection may be provided. A data stream may be received and a determination may be made whether at least one non-audio element associated with the data stream indicates that the data stream comprises speech. In response to determining that the at least one non-audio element associated with the data stream indicates that the data stream comprises speech, a speech to text conversion may be performed on at least one audio element associated with the data stream.
