Embodiment 1

[0094] Considering the technical problems of low user wake-up rate, high false wake-up rate and poor user experience in the existing fixed wake-up word voice wake-up method; Experience voice wake-up methods, such as figure 1 As shown, the voice wake-up method of the present embodiment includes the following steps:

[0095] Step 101: collect the wake-up word voice signal sent by the terminal user, obtain and store the wake-up word recognition result and voiceprint feature of the wake-up word voice signal.

[0096] The method in this embodiment may use a voice collection device, such as a microphone, to collect the voice signal sent by the terminal user. In the method of this embodiment, the sequence of obtaining the recognition result of the wake-up word and the voiceprint feature is not limited. The recognition result can be obtained first, and then the voiceprint feature can be obtained, or can be obtained at the same time.

[0097] In this embodiment, the wake-up word reco...

Embodiment 2

[0168] In order to further improve the user experience, after the terminal wakes up, it is possible to perform a variety of fast and automatic responses, such as opening applications, etc. This embodiment provides a terminal processing method based on the above-mentioned voice wake-up method, such as Figure 6 shown, including the following steps:

[0169] Step 601: Use the voice wake-up method described in Embodiment 1 to wake up the terminal.

[0170] For a specific wake-up process, refer to the specific description of Embodiment 1.

[0171] Step 602: After the terminal wakes up, perform a corresponding preset operation according to the voice recognition result of the voice signal.

[0172] The above step 602 can be completed by the main processor in the terminal.

[0173] The method in this embodiment can pre-set and automatically define the response operation corresponding to the wake-up word, and different wake-up words can correspond to different response operations; a...

Embodiment 3

[0184] Such as Figure 7 As shown, this embodiment provides a voice wake-up device, which is characterized in that it includes: a sampling module, a detection module, a first acquisition module, a second acquisition module, a first judgment module and a wake-up module; the sampling module is used for Collecting the wake-up word voice signal sent by the terminal user, obtaining the wake-up word recognition result and the voiceprint feature of the wake-up word voice signal and storing them;

[0185] The detection module is used to detect a voice signal input from the outside when the terminal is in a dormant state;

[0186] The first acquisition module is used to acquire the speech recognition result and voiceprint features of the speech signal;

[0187] The second obtaining module is used to obtain the speech recognition result and the stored wake-up word recognition result, and the matching result between the voiceprint feature and the stored voiceprint feature;

[0188] The...

Abstract

The invention discloses a voice wake-up method and apparatus, a terminal, and a processing method thereof. The voice wake-up method comprises: a wake-up word voice signal sent out by a terminal user is collected and a wake-up word identification result and a vocal print feature of the wake-up word voice signal are obtained and stored; when a terminal is in a sleep state, a voice signal inputted externally is detected; a voice identification result and a vocal print feature of the voice signal are obtained; the voice identification result and the stored wake-up word identification result as well as a matching result of the vocal print feature and the stored vocal print feature are obtained; and according to the matching result, whether the terminal needs to be woken up is determined; and if so, the terminal is woken up. With the method, technical problems of low user wake-up rate, high wrong wake-up rate, and poor user experience according to the existing voice wake-up technology are solved.

Description

technical field [0001] The present invention relates to the technical field of voice recognition, in particular to a voice wake-up method and device, a terminal and a processing method thereof. Background technique [0002] Voice in the mobile terminal does not only exist in a separate program application, but gradually becomes a new input method independent of finger touch input, without touching the mobile phone, remote control and more intelligent and friendly services. Mobile phone users. [0003] The voice wake-up technology provides the premise for users to liberate their hands and completely control the mobile phone with voice commands. The mainstream wake-up technology is technical software wake-up, but the software runs on the premise of starting the mobile phone system. In order to ensure that the user's voice commands can be received anytime and anywhere, the voice engine It needs to run and monitor in the background all the time, and the mobile phone system will...
