    • The subject matter of this specification can be embodied in, among other things, a method that includes receiving an audio signal and initiating speech recognition tasks by a plurality of speech recognition systems (SRS's). Each SRS is configured to generate a recognition result specifying possible speech included in the audio signal and a confidence value indicating a confidence in a correctness of the speech result. The method also includes completing a portion of the speech recognition tasks including generating one or more recognition results and one or more confidence values for the one or more recognition results, determining whether the one or more confidence values meets a confidence threshold, aborting a remaining portion of the speech recognition tasks for SRS's that have not completed generating a recognition result, and outputting a final recognition result based on at least one of the generated one or more speech results.
    • 除了别的以外,本说明书的主题可以体现在包括通过多个语音识别系统(SRS)接收音频信号和发起语音识别任务的方法。 每个SRS被配置为产生指定包括在音频信号中的可能语音的识别结果,以及指示对语音结果的正确性置信度的置信度值。 该方法还包括完成语音识别任务的一部分,包括生成一个或多个识别结果和一个或多个识别结果的一个或多个置信度值,确定一个或多个置信度值是否满足置信阈值,中止其余部分 的尚未完成生成识别结果的SRS的语音识别任务,并且基于所生成的一个或多个语音结果中的至少一个来输出最终识别结果。
