    Abstract: A new audio playback architecture may be used, which allows the use of much larger buffering than that used by a typical audio subsystem in a computing system to improve power efficiency of the system and at the same time allows to maintain the quality (e.g., fidelity and responsiveness) of the audio playback. The audio controller in the new architecture may be made to report back to the host system a more accurate indication of which audio frame is being set to the audio codec than a currently available audio controller does. Additionally, the controller is capable of re-fetching previously buffered (but not yet transmitted) data. Furthermore, buffers in both the audio controller and the main memory may be dynamically adjusted during playback of audio data and/or for different applications.

    Abstract translation: 可以使用新的音频回放架构，其允许使用比计算系统中的典型音频子系统使用的更大的缓冲以提高系统的功率效率，并且同时允许保持质量（例如，保真度 和响应性）的音频播放。 可以使新架构中的音频控制器向主机系统报告比当前可用的音频控制器更准确地指示哪个音频帧被设置为音频编解码器。 此外，控制器能够重新获取先前缓存的（但尚未发送）的数据。 此外，音频控制器和主存储器中的缓冲器可以在音频数据和/或不同应用的回放期间被动态调整。

    Abstract: A computer includes a wireless personal area network (WPAN) interface, a wireless local area network (WLAN) interface and a wireless wide area network (WWAN) interface. A device communicating with the wireless personal area network can command the computer to perform actions using the wireless local area network interface or wireless wide area network interface.

    Abstract: A speech-recognition system learns a speech profile of a user whose speech is to be recognized. The system plays audible speech samples, stored in sound files, so that the file that most resembles the user's speech may be selected. After receiving the selection, the system identifies an acoustic model that is associated with the chosen sound file. The system may also select a subset of sound files based on information indicative of the user's speech. The system may then play a subset of sound files so that the file that most resembles the user's speech may be selected.
