Abstract: A method and apparatus for synchronizing media content emitted from various sources is presented. Arrival timing of outputs from the various sources to a particular location is determined and adjusted to reduce synchronization delays at the particular location. Synchronization delays may be determined by detecting the media output from a combination of sources arriving at the location. Control messages are generated by processing the detected output and determining delays to be applied to corresponding sources.

Abstract: In a distributed automated speech recognition (ASR) system, speech models may be employed on a local device to allow the local device to process frequently spoken utterances while passing other utterances to a remote device for processing. Upon receiving an audio signal, the local device compares the audio signal to the speech models of the frequently spoken utterances to determine whether the audio signal matches one of the speech models. When the audio signal matches one of the speech models, the local device processes the utterance, for example by executing a command. When the audio signal does not match one of the speech models, the local device transmits the audio signal to a second device for ASR processing. This reduces latency and the amount of audio signals that are sent to the second device for ASR processing.

Abstract translation: 在分布式自动语音识别（ASR）系统中，可以在本地设备上使用语音模型，以允许本地设备处理频繁的口语话语，同时将其他话语传送到远程设备进行处理。 在接收到音频信号时，本地设备将音频信号与经常说出的话语的语音模型进行比较，以确定音频信号是否与语音模型中的一个匹配。 当音频信号与语音模型中的一个匹配时，本地设备例如通过执行命令来处理话音。 当音频信号与语音模型之一不匹配时，本地设备将音频信号发送到用于ASR处理的第二设备。 这减少了延迟和发送到第二设备的ASR处理的音频信号量。
