阅读说明：本技术 用于利用语音开始检测来唤醒短语检测的双管线体系结构 (Dual pipeline architecture for wake phrase detection with voice onset detection ) 是由 维克托·西米利斯基 罗伯特·措普夫 于 2019-02-22 设计创作，主要内容包括：短语检测设备包括：将音频数据的第一部分从音频数据源传送到处理单元的高时延管线,其中高时延管线包括存储音频数据的第一部分的历史缓冲器；以及以比高时延管线更低的时延将音频数据的第二部分从音频数据源传送到处理单元的低时延管线。与音频数据源耦合的声音开始检测器基于音频数据来检测声音开始事件。与高时延管线和低时延管线耦合的同步电路响应于声音开始事件而使存储在历史缓冲器中的音频数据的第一部分到处理单元的输出和音频数据的第二部分经由低时延管线到处理单元的输出同步。(The phrase detection apparatus includes: a high latency pipeline to communicate a first portion of the audio data from the audio data source to the processing unit, wherein the high latency pipeline includes a history buffer to store the first portion of the audio data; and a low-latency pipeline to communicate a second portion of the audio data from the audio data source to the processing unit with a lower latency than the high-latency pipeline. A sound onset detector coupled to the source of audio data detects a sound onset event based on the audio data. A synchronization circuit coupled to the high-latency pipeline and the low-latency pipeline synchronizes an output of the first portion of the audio data stored in the history buffer to the processing unit and an output of the second portion of the audio data to the processing unit via the low-latency pipeline in response to the sound onset event.)
