Embodiment 1

[0070] figure 1 It is a flowchart of a method for preventing misrecognition of voice commands provided by Embodiment 1 of the present invention. The method of this embodiment can be executed by a device for preventing misrecognition of voice commands, which can be implemented by means of hardware and / or software, and Generally, it can be integrated into devices that have voice command control function and can play audio files, such as mobile phones, cars, etc. The method of this embodiment specifically includes:

[0071] Step 110, acquiring a lyrics file matching the song to be played.

[0072] Generally speaking, in the prior art, a device that has both voice command control function and audio file playback function will play the audio file directly when it obtains the command to play the audio file, and will not reduce the audio file size before playing. Actions that misrecognize voice commands due to playing songs.

[0073] In this embodiment, before playing the song to ...

Embodiment 2

[0089] figure 2 It is a flowchart of a method for preventing misrecognition of voice commands provided by Embodiment 2 of the present invention. This embodiment optimizes on the basis of above-mentioned embodiment, and in this embodiment, the lyrics file is optimized as Chinese lyrics file;

[0090] Optimize the preset voice control commands to Chinese voice control commands;

[0091]Correspondingly, the error-prone phrase in the search lyrics file is optimized as: traversing the pronunciation attributes of all Chinese lyrics in the Chinese lyrics file, wherein the pronunciation attributes at least include tone, initial consonant and final; if a Chinese character or a Each Chinese character in the Chinese character phrase is all the same as the pronunciation attribute of the Chinese character in the corresponding position in the Chinese voice control command, then confirm that the Chinese character or Chinese character phrase is the same as the language of the Chinese voice ...

Embodiment 3

[0128] image 3 It is a flowchart of a method for preventing misrecognition of voice commands provided by Embodiment 3 of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiment. In this embodiment, according to the lyrics file, the first start time and the first end time of calculating the error-prone trigger phrase playback are optimized as: according to the lyrics file, obtain the error-prone trigger The second start time and the second end time of the lyrics sentence to which the phrase belongs; the first compensation time of the first start time and the second compensation time of the first end time; according to the second start time and the second end time , the first compensation time, the second compensation time, the number of lyric units included in the lyric sentence, the number of lyric units included in the easily false trigger phrase and the position of the easily false trigger phrase in the lyric sentence, calculate th...

Abstract

The embodiments of the invention disclose a method and apparatus for preventing voice command misidentification. The method comprises the following steps: obtaining a lyrics file matching a song to be played; searching for a phrase which can be wrongly triggered easily in the lyrics file; according to the lyrics file, calculating first initial time and first finishing time of play of the phrase which can be wrongly triggered easily; and playing the song to be played, closing a voice identification module when it is the first initial time, and starting the voice identification module when it is the first finishing time. According to the technical scheme provided by the embodiments of the invention, the technical defects of increased processor calculation burden, rising equipment power consumption and difficult voice identification algorithm transplantation which are caused by increased complexity of a voice identification algorithm for reducing the probability of voice wrong trigger in the prior art are overcome, and voice misidentification caused by song play can also be reliably reduced without improving the complexity of the voice identification algorithm.

Description

technical field [0001] Embodiments of the present invention relate to data processing technologies, and in particular to a method and device for preventing misrecognition of voice commands. Background technique [0002] With the continuous development of science and technology, and people's constant pursuit of higher quality of life, more and more devices have voice control functions. [0003] Most of cars, household appliances and mobile phones are equipped with voice control functions. These devices can also play audio files such as songs and comic dialogues. When these devices are playing audio files, the voice control function may be turned on by mistake, causing the device to make wrong action. In the prior art, by increasing the complexity of the speech recognition algorithm and optimizing the speech recognition algorithm, the probability of false triggering is reduced. [0004] The disadvantages of the prior art are: increasing the computational burden of the CPU le...
