Problems solved by technology

[0002] In recent years, the vehicle industry has developed rapidly, and the use of voice is also increasing. However, because the voice technology is not mature enough, every time you use the voice function, you need to use a wake-up word to tell the voice assistant that I will start talking to you, which is very troublesome. Generally, only the driver has a wake-up voice button in the car, while other passengers can only wake up with their mouths, and currently they can only receive voice commands from one person at a time.

Abstract

The invention provides a directional sound receiving device and a vehicle-mounted voice triggering method. The device is applied to a vehicle and comprises a plurality of voice wake-up buttons and a plurality of microphone arrays, the wake-up voice buttons are distributed at one or more positions of a main driving position, a co-driving position and a rear row position of the vehicle, the wake-upvoice buttons are electrically connected with one or more microphone arrays, and the microphone arrays are used for collecting voice signals of passengers. Embodiments according to the present invention, voice signals can be directionally collected for passengers who open the wake-up voice button, the voice assistant awakening accuracy of passengers is improved, meanwhile, the microphone array atthe corresponding position directionally collects the voice signals, the accuracy of collecting the voice signals of the passengers is improved, the voice interaction experience of the passengers at different positions in the vehicle is improved, and the passengers awaken the voice assistant through the buttons, so that the use cost of voice service can be reduced.

Description

technical field [0001] The present application relates to the technical field of vehicle and intelligent voice interaction, in particular to a directional sound collection device and a vehicle voice trigger method. Background technique [0002] In recent years, the vehicle industry has developed rapidly, and the use of voice is also increasing. However, because the voice technology is not mature enough, every time you use the voice function, you need to use a wake-up word to tell the voice assistant that I will start talking to you, which is very troublesome. Generally, only the driver has a wake-up voice button in the car, while other passengers can only wake up with their mouths, and currently they can only receive voice commands from one person at the same time. Contents of the invention [0003] In view of this, the present application provides a directional sound collection device and a vehicle-mounted voice trigger method, which can collect voice signals in a directi...
