摘要： Disclosed are embodiments for seamless, single-step, and speech-triggered transition of a host processor and/or computing device from a low functionality mode to a high functionality mode in which full vocabulary speech recognition can be accomplished. First audio samples are captured by a low power audio processor while the host processor is in a low functionality mode. The low power audio processor may identify a predetermined audio pattern. The low power audio processor, upon identifying the predetermined audio pattern, triggers the host processor to transition to a high functionality mode. An end portion of the first audio samples that follow an end-point of the predetermined audio pattern may be stored in system memory accessible by the host processor. Second audio samples are captured and stored with the end portion of the first audio samples. Once the host processor transitions to a high functionality mode, multi-channel full vocabulary speech recognition can be performed and functions can be executed based on detected speech interaction phrases.

摘要： Techniques to output a media stream, capture a media stream, or synchronize the output or capture of the media stream at a specified time are described. A media stream output or capture apparatus may include a media processor to receive a media stream to output or a request to capture a media stream and a start time. A buffer generator may be included to generate an input or an output buffer and a media mixer may be included to mix the media stream into the output buffer at the start time or capture the media stream from the input buffer at the start time.

摘要： Systems and methods may provide for monitoring an input audio signal from an onboard microphone of a mobile device while a host processor of the mobile device is in a standby mode. Additionally, a predetermined audio pattern may be identified in the input audio signal and a device location session may be triggered with respect to the mobile device based on the predetermined audio pattern. In one example, an output audio signal is generated during the device location session.
