An electronic device includes circuitry, firmware, and software that determines identification information associated with a first performer-of-interest at a live event and retrieves a first set of audio tracks from a plurality of audio tracks based on the determined identification information. The circuitry receives a first audio segment associated with the first performer-of-interest from an audio capturing device. The circuitry compares a first audio characteristic of the first audio segment with a second audio characteristic of a first audio portion of each of the first set of audio tracks. The circuitry determines a first audio track based on the comparison between the first audio characteristic and the second audio characteristic. The circuitry identifies a start position of the first audio track based on the first audio segment associated with the first audio track. The circuitry controls a display of the first lyrics information of the first audio track.

Systems and methods for facilitating contextual queries based on media samples automatically captured by a computing device are disclosed herein. A server receives from a computing device over a communication network, a media sample of a media asset automatically captured by the computing device. The server obtains contextual information corresponding to the captured media sample. The server stores the media sample in a memory indexed by the contextual information. The server receives, from the computing device over the communication network, a query that includes a criterion but lacks an identifier of the media asset. The server identifies the media sample in the memory by matching the query criterion to the contextual information. The server generates a reply to the query based on the identifying of the media sample and communicates the reply to the computing device over the communication network.

A shot fired detector can receive an audio signal or acoustic stream and determine that a firearm has been discharged. One or more detectors can be used to continuously capture acoustic streams and process the acoustic streams for anomaly detection. A detected anomaly can be classified by a machine learning model to detect that a shot has been fired. The detector can send acoustic data and meta data associated with the shot fired to a server for further storage and/or processing. An alert can be automatically generated that is associated with the shot fired.

Embodiments of the present disclosure disclose a playlist switching method, apparatus and system, a terminal and a storage medium. The method includes: generating a playlist switching request according to a trigger operation of a creator of a singing room, and sending the playlist switching request to a service, where the playlist switching request includes a target playlist identification and a singing room identification after switching (S110); and in case of receiving switching success information, displaying playlist information corresponding to the target playlist identification on a display interface (S120).

Systems and methods for generating a playlist of audio content for a vehicle are disclosed. An audio input is received at a vehicle entertainment system of the vehicle while an audio content item is currently played by the vehicle entertainment system. The audio input includes an audio command trigger and an audio playlist command. In response to detecting the audio command trigger in the audio input, the audio input is parsed to determine the audio playlist command. A metadata associated with the audio content item is determined. In response to determining the audio playlist command, the audio content item is caused to be added to an audio content playlist of a third-party service based on the metadata of the audio content item.

The present disclosure provides systems and methods that provides users with information pertaining to the audio properties at one or more points of interest. A database associated the audio properties with the points of interest is built using audio input received from devices at the points of interest. The device may determine that audio properties associated with the received audio input. The audio properties may determine a type of background noise and/or a volume of the background noise. If the type of background noise is music, the audio properties may further include a music genre, a title of a song, whether the music is recorded or there is a live band, etc. The audio properties associated with the point of interest may be updated in a database real time.
