Technical field
The present invention relates to intelligent vehicle-carried apparatus fields, a kind of awakening method more particularly, to vehicle intelligent equipment and
Rouser.
Background technique
With becoming increasingly popular for artificial intelligence technology, the software and hardwares product such as various artificial intelligence companies, voice assistant enters
Public daily life.Especially scene, various artificial intelligent voice assistants are increasingly becoming the virtual " secondary of driver in the car
Drive ", convenient service is provided when driving for driver.Currently, various car voice assistant products all use voice wake-up side
Formula says specific wake-up word by user, and interior voice assistant is waken up and starts recording reception user's next step phonetic order.
Due to the limitation of environment inside car, the mode that this pure speech wakes up is had some limitations, when car plays music, passenger
When sound of speaking is big or environment is noisy, due to the limitation of current voice semanteme analytic technique, in wake up instruction audio
Mix the audio-source of other complex environment sound, can not effectively remove and identify the wake up instruction keyword in audio, because
This causes voice to wake up failure.
Although patent CN108181992 A discloses a kind of voice awakening method based on gesture, acquire the gesture of user
Image；Judge whether the images of gestures of user matches with pre-set image；When the images of gestures of user matches with pre-set image
When, wake up voice interactive function.Although it can improve wake-up success rate to a certain degree, it is needed through Image Acquisition mould
Block acquires images of gestures and is compared with pre-set image.Its wake actions is complicated, and increased image capture module cost
It is higher.
