In some implementations, authentication tokens corresponding to known users of a device are stored on the device. An utterance from a speaker is received. The speaker of the utterance is classified as not a known user of the device. A query that includes the authentication tokens that correspond to known users of the device, a representation of the utterance, and an indication that the speaker was classified as not a known user of the device is provided to the server. A response to the query is received at the device and from the server based on the query.

Methods for the operator control of electronic appliances and appropriately set-up electronic appliances in which an input of at least one letter is captured independently of an input request, and a volume of data is displayed on a screen of the electronic appliance on the basis of the captured letter. The input may be made by handwriting or by voice input, for example.

A motor vehicle includes a source of pieces of music. Each of the pieces of music is associated with respective weather conditions and/or a respective emotional mood. The vehicle includes a source of weather data. The weather data is related to weather conditions in which the motor vehicle is operating. The vehicle includes a source of mood data. The mood data is related to an emotional state of a human user disposed within the motor vehicle. A loudspeaker is disposed within a passenger compartment of the motor vehicle. A processing device is communicatively coupled to each of the source of pieces of music, the source of weather data, the source of mood data, and the loudspeaker. The processing device selects one of the pieces of music dependent upon the weather data and the mood data, and plays the selected piece of music on the loudspeaker.

It is an object of the present invention to provide a technique capable of performing user estimation without making the user aware of it. The appliance has a first sensor input unit that inputs a plurality of control commands for controlling an operation, and estimates the user based on the control command input to the first sensor input unit and an operation feature amount at the time of inputting the control command. The first sensor input unit includes a touch panel. The operation feature amount includes an operation position of the touch panel, an electrostatic capacitance value corresponding to a pressing of the touch panel, and a time-dependent change pattern thereof.

Devices and methods to track contact between persons using acoustic voiceprint identification from stored audio signals are presented herein.

In-ear sound pressure level, SPL, is determined that is caused by output audio being converted into sound by a headset worn by a user. The in-ear SPL is converted into a sound sample having units that are suitable for evaluating sound noise exposure. These operations are repeated to produce a sequence of sound samples during playback. This sequence of sound samples is then written to a secure database. Access to the database is authorized by the user. Other aspects are also described and claimed.

A system and method for controlling a non-tactile device including a receiving device configured to receive signals corresponding to a user's brain waves or movements, the brain waves or movements corresponding to a series of directional intentions, the intentions defining at least one line pattern, a processor configured to process the at least one line pattern, each of said at least one line patterns associated with an action of the device, and output a control signal to the non-tactile device related to the action.

A method remixing/restructuring of audio within an audio file selection includes steps of creating arrangeable music for a musical composition stored as an original audio file and creating a plurality of custom arrangements of the musical composition. Each custom arrangement of the plurality of custom arrangements is tailored to any combination of a location where a custom arrangement is to be played, a day of the week when the custom arrangement is played, an assessment of crowd participation, activity that a user is engaged in, and an assessment of an emotional state of the user. The custom arrangements are provided on-demand to the user for execution, wherein the are executed by a remixing/restructuring system that includes a backend computing device such that at least one of the steps are at least partially executed on a backend computing device.

In some implementations, authentication tokens corresponding to known users of a device are stored on the device. An utterance from a speaker is received. The speaker of the utterance is classified as not a known user of the device. A query that includes the authentication tokens that correspond to known users of the device, a representation of the utterance and an indication that the speaker was classified as not a known user of the device is provided to the server. A response to the query is received at the device and from the server based on the query.

Systems and methods for social media music streaming may include (1) providing a music service within a social media platform, (2) detecting a group chat between two or more members of the social media platform, and (3) creating, via the music service, a shared music station for the members of the group chat. Various other methods, systems, and computer-readable media are also disclosed.
