    摘要： A system capable of connecting a device to a Public Switched Telephone Network (PSTN) using an adapter. The device may send audio data via a data network to a server and the server can determine a voice command included in the audio data. Based on the voice command, the server may send an instruction to an adapter via the data network, the instruction causing the adapter to initiate a telephone call over the PSTN. During the telephone call, the adapter and the server may forward audio data between the device and the PSTN, enabling the device to communicate over the PSTN. The system may enable the device to receive an incoming call from the PSTN and may provide additional functionality, such as determining call statistics during the telephone call, determining if another telephone receives audio data during the telephone call and detecting an alarm signal sent via the PSTN.

    摘要： Techniques for receiving a voice command from a user and, in response, providing audible content to the user via a first device and providing visual content for the user via a second device. In some instances, the first device includes a microphone for generating audio signals that include user speech, as well as a speaker for outputting audible content in response to identified voice commands from the speech. However, the first device might not include a display for displaying graphical content. As such, the first device may be configured to identify devices that include displays and that are proximate to the first device. The first device may then instruct one or more of these other devices to output visual content associated with a user's voice command.

    摘要： Techniques for altering audio being output by a voice-controlled device, or another device, to enable more accurate automatic speech recognition (ASR) by the voice-controlled device. For instance, a voice-controlled device may output audio within an environment using a speaker of the device. While outputting the audio, a microphone of the device may capture sound within the environment and may generate an audio signal based on the captured sound. The device may then analyze the audio signal to identify speech of a user within the signal, with the speech indicating that the user is going to provide a subsequent command to the device. Thereafter, the device may alter the output of the audio (e.g., attenuate the audio, pause the audio, switch from stereo to mono, etc.) to facilitate speech recognition of the user's subsequent command.
