A battery case is operable with an electronic device such as a cellular telephone. The battery case has a battery that can be used to supply power to the electronic device. The battery case is configured to receive power from a power supply that is coupled to a mains power supply using a wired path or to receive power from a wireless charging mat or other wireless power transmitting device. Circuitry in the battery case may include direct-current-to-direct-current power converter circuitry, current sensor circuitry, switching circuitry, and other circuitry for controlling currents and voltages in the battery case and communicating with other electronic devices.

The disclosed embodiments include methods, devices, and storage mediums for adjusting the output volume of audio content. In one aspect, a method performed at an audio device includes: (1) identifying a remote location for audio content; (2) streaming the audio content from the remote location; (3) producing an audible output from the audio content at a first volume level; and (4) while producing the audible output: (a) receiving an indication that a user is about to submit verbal input to the electronic device; (b) in response to the indication, adjusting the audible output from the first volume level to a second volume level, less than the first volume level; (c) receiving the verbal input from the user; and (d) after receiving the verbal input, adjusting the audible output from the second volume level to the first volume level.

Utterances of at least two speakers in a speech signal may be distinguished and the associated speaker identified by use of diarization together with automatic speech recognition of identifying words and phrases commonly in the speech signal. The diarization process clusters turns of the conversation while recognized special form phrases and entity names identify the speakers. A trained probabilistic model deduces which entity name(s) correspond to the clusters.

Systems and methods for voice-enabled configurations for audio-output devices are disclosed. User accounts may be associated with one or more voice-enabled devices. Those voice-enabled devices may include audio-output functionality, while other voice-enabled devices do not include audio-output functionality. For devices without audio-output functionality, sending and/or receiving calls and/or messages may depend on whether the device is connected to an auxiliary device with audio-output functionality, via wired and/or wireless connection. Notifications of whether calling and/or messaging is enabled may be sent to the sending and/or receiving devices.

A system and method for making a call to a service provider on behalf of a user is disclosed. The system and method include using an intelligent voice assistant to call the service provider and having the intelligent voice assistant navigate an interactive voice response system to reach a representative. The system and method also include using the intelligent voice assistant to reconnect a user with a representative after an interrupted call.

A method on a mobile device for a wireless network is described. An audio input is monitored for a trigger phrase spoken by a user of the mobile device. A command phrase spoken by the user after the trigger phrase is buffered. The command phrase corresponds to a call command and a call parameter. A set of target contacts associated with the mobile device is selected based on respective voice validation scores and respective contact confidence scores. The respective voice validation scores are based on the call parameter. The respective contact confidence scores are based on a user context associated with the user. A call to a priority contact of the set of target contacts is automatically placed if the voice validation score of the priority contact meets a validation threshold and the contact confidence score of the priority contact meets a confidence threshold.

The disclosed embodiments include computerized methods, systems, and devices, including computer programs encoded on a computer storage medium, for generating terms of a search query based on a user's spoken utterances, identifying multiple cross-platform messages based on the generated terms, and to generating, via a presentation device, a single interface that enables the user to interact with identified messages. Based on a spoken utterance, the disclosed embodiments may determine user-specified search terms and/or criteria, and based on the user-specified search terms and/or criteria, may obtain cross-platform message data that corresponds to the search query. The communications device may generate one or more interface elements that describe corresponding ones of the cross-platform messages, which may be presented within a unified graphical user interface or voice-user interface by a communications device.

An apparatus and method for processing call services in a mobile terminal are provided. The method for processing call services in a mobile terminal includes entering into, when a call is generated, a call handling mode, recognizing and analyzing voice signals sent and received in the call to produce speech analysis information, detecting a state change of the mobile terminal using a sensing unit to produce user behavior information, and predicting, when a state change of the mobile terminal is detected, an application corresponding to the speech analysis information, and activating the application as a follow-up service.

Each user of a telecommunications system may speak and record their own name, in their own voice, and a recording of their spoken name may subsequently be accessed by or delivered to other users of the system, thereby facilitating communication between users by enabling users to better know how to pronounce the names of other users. A user may listen to the recorded spoken name of another user before placing a call to another user. When a user joins a conference call, their spoken name may be announced to other users (attendees) already in the call. A user joining a conference call may listen to the recorded spoken names of attendees in the call. A button on users' phones may invoke these features.

A device and method for responding to a user voice including an inquiry by outputting a response to the user's voice through a speaker and providing a guide screen including a response to the user's voice.
