The present disclosure discloses a wireless connection establishment method, an apparatus, a device and a storage media, which is applied to artificial intelligence, Internet of Vehicles and intelligent transportation technologies in the field of computer technology. A specific implementation scheme is as follows: by before establishing a WiFi direct connection between a car machine apparatus and a terminal device, a Bluetooth communication connection between the two is established firstly, the car machine apparatus provides parameter information required to establish the WiFi direct connection with the car machine apparatus to the terminal device through the Bluetooth communication connection, then the terminal device can automatically send a WiFi direct connection request to the car machine apparatus based on the parameter information, and the car machine apparatus device establishes the WiFi direct connection with the terminal device in response to the WiFi direct connection request initiated by the terminal device.

Wireless connection establishment method, apparatus, device, and storage medium

A method and an apparatus for outputting information are provided. The method includes acquiring voice information received within a preset time period before a device is awakened, where the device is provided with a wake-up model for outputting preset response information when a preset wake-up word is received; performing speech recognition on the voice information to obtain a recognition result; extracting feature information of the voice information in response to determining that the recognition result does not include a preset wake-up word; generating a counterexample training sample according to the feature information; and training the wake-up model using a counter-example training sample, and outputting the trained wake-up model.

Method and apparatus for outputting information

A method for processing a touch instruction, an electronic device and a storage medium, related to the fields of Internet of Things, intelligent transportation, and the like, are provided. The method includes: detecting a type of a received touch event; in a case where the type of the touch event is a predetermined type, acquiring a number of fingers which execute the touch event of the predetermined type each time; and determining a touch instruction by utilizing a change situation of the number of fingers which execute two adjacent touch events of the predetermined type. According to the solution, the number of fingers which execute the touch event can be determined by utilizing the change situation of the number of fingers corresponding to two adjacent touch events conforming to the predetermined type.

Method for determining touch instruction, electronic device and storage medium

The present disclosure provides a voice wake-up processing method, an apparatus and a storage medium. After acquiring voice wake-up signals collected by audio input devices in at least two audio zones, an electronic device may correct, based on to-be-woken-up audio zones obtained from amplitudes of the voice wake-up signals collected by the audio input devices in the at least two audio zones, a to-be-woken-up audio zone identified using a voice engine, avoiding that audio zones in which a plurality of audio input devices collecting voice wake-up signals produced from a same user are located are all woken up, therefore, it is possible to improve accuracy of a voice wake-up result obtained by the electronic device. Therefore, the present disclosure can solve the technical problem that a vehicle-mounted terminal has low voice wake-up accuracy due to an insufficient degree of sound isolation between audio zones of the vehicle-mounted terminal.

Voice wake-up processing method, apparatus and storage medium

Embodiments of the present disclosure disclose a method and a device for obtaining an amplitude for a sound zone, a related electronic device and a storage medium. The method includes the following. Speech data of a target sound zone is obtained in real time. The speech data includes audio signals corresponding to a plurality of sampling points. The audio signals are stored by comparing an amplitude of a current audio signal to be stored with an amplitude of each stored audio signal to determine whether to store the current audio signal according to a comparison result. A current amplitude for the target sound zone is calculated according to amplitudes of all stored audio signals.

Method and device for obtaining amplitude of sound in sound zone

An in-vehicle voice command recognition method and apparatus, and a storage medium. The method includes: acquiring a voice command inputted by a user; determining basic information of the user according to a pre-trained deep neural network (DNN) model; identifying contents of the voice command according to the basic information of the user, and determining at least one potential user intention according to the identified contents and a scenario page context at the time when the user inputs the voice command; determining a confidence level of the potential user intention according to the DNN model; determining a real user intention from the potential user intention according to the confidence level; and executing a corresponding action according to the real user intention. The embodiments of the present disclosure can effectively improve the correct recognition rate of voice commands.
