Embodiment Construction

[0035] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0036] In order to solve the problem existing in the existing voice interaction method that the efficiency of voice interaction is affected by the forced segmentation of voice commands, the present invention provides a more efficient voice interaction method, such as figure 1 As shown, the method includes the following steps:

[0037] Step S1: Record audio data input by the user.

[0038] Here, the recorded audio data can be stored in a fixed-length circular buffer, and the storage address can be recorded for subsequent steps to obtain ...

Abstract

The invention discloses a voice interaction method and system. The method includes recording audio data input by a user; performing endpoint detection on the audio data until the voice front-end point is detected; performing prefix word detection on the audio data from the voice front-end point, Until the prefix word voice is detected, the prefix word is a word reflecting the type of execution action; the voice segment starting from the front end point of the prefix word voice in the audio data is obtained as a voice command; the voice command is voice recognized; if the voice recognition result is valid then Perform operations corresponding to speech recognition results. The method and system of the present invention use the speech segment starting from the front end of the prefix word voice in the audio data as the speech instruction, and use the words reflecting the type of execution action as the prefix word, thus realizing the organic combination between the prefix word and the speech instruction , which can effectively avoid the problem that an effective voice recognition result cannot be obtained due to the forced segmentation of voice commands, and improve the efficiency of voice interaction.

Description

technical field [0001] The invention relates to the field of voice interaction, in particular to a voice interaction method and system. Background technique [0002] In order to prevent mobile devices such as mobile phones from misidentifying surrounding speech noises as voice commands when they are in standby, the mobile device needs to complete the following operations every time the user activates the voice interaction function of the mobile device: 1. Record the audio data input by the user; 2. Obtain audio data for wake-up detection until the wake-up is successful; 3. Prompt the user to input a voice command after the wake-up is successful; 4. After prompting the user to input a voice command, record the audio data input by the user again; 5. Obtain the re-recorded audio The voice segment in the data is used as a voice command; 6. Perform voice recognition on the voice command to obtain a voice recognition result; 7. Determine whether the voice recognition result is val...
