The content of multimedia that lecture notes can be embodied in the way of lyrics file.
Step 120, the easy false triggering phrase searched in lyrics file, wherein, easy false triggering phrase and default Voice command
The language of order is same or like.
In the present embodiment, easy false triggering phrase specifically refers to cause the word of default voice control command false triggering
Group, that is, the phrase that pronunciation is same or like with the pronunciation of the language of default voice control command.Wherein, default Voice command
Order specifically refers to prestore, and can be used to implement voice-operated language.
Due to may there is easy false triggering phrase in the lyrics, lead to song during playing, cause Voice command
Order misrecognition, does the operation making mistake, and therefore, in the present embodiment, after obtaining the lyrics file of song to be played, first can
Search whether the lyrics in this lyrics file include easy false triggering phrase.
Wherein, the concrete mode searching easy false triggering phrase can be that all lyrics traveling through in lyrics file are searched and pre-
If voice control command in each Chinese character tone, initial consonant and simple or compound vowel of a Chinese syllable all same phrase as easy false triggering phrase,
Can be that all lyrics lookups traveling through in lyrics file are equal with the phonetic symbol of each English word in default voice control command
Identical phrase is as modes such as easy false triggering phrases.Wherein, all lyrics in traversal lyrics file search easy false triggering word
The mode of group can be to search just for a default voice control command to correspond to therewith while traveling through all lyrics
Easy false triggering phrase that is to say, that how many default voice control command will travel through how many all over all lyrics, also may be used
To be only to travel through all lyrics, search easy false triggering while traversal compared with all of default voice control command
Phrase will be entered with all of default voice control command when any one word or word in the lyrics that is to say, that often traversing
Row contrast.
It is further to note that being only illustrated for two kinds of situations of Chinese and english to the lyrics above, work as the lyrics
During for language beyond Chinese and english, the method for the present embodiment is equally applicable, because either any language, all to should have
The distinctive phone set of this language, and the pronunciation of all single word of this language or single word be all by this language distinctive one or
Multiple phonemes are constituted, when searching easy false triggering phrase it is possible to be used the distinctive phoneme of this language as the basis of comparison, when
When certain word or certain phrase are same or like with the phoneme of each word or each word in default voice control command, then judge
This word or this phrase are easy false triggering phrase.
Step 130, according to lyrics file, at the end of calculating the first initial time and first that easy false triggering phrase is play
Between.
In the present embodiment, the first initial time specifically refers to the time that easy false triggering phrase commences play out, the first end
Time specifically refers to the time that easy false triggering phrase terminates to play, and wherein, the first initial time and the first end time are all phases
The concrete time calculated for the initial reproduction time of song to be played, the initial reproduction time of song to be played can be remembered
Record as 0 point of 0 second 0 millisecond or 0 point of time format such as 0 second.
In the present embodiment, due to this easy false triggering phrase when searching easy false triggering phrase, can be known in song simultaneously
Particular location in word is (for example：The the 3rd to the 6th word in the 5th lyrics), and every can be known according to lyrics file
The temporal informations such as the initial reproduction time of the lyrics, therefore, according to particular location in the lyrics for the easy false triggering phrase and every
The temporal informations such as the initial reproduction time of the lyrics can relatively easily calculate that easy false triggering phrase plays first initial when
Between and the first end time.
Further, due to it cannot be guaranteed that each lyrics are all typically will not be detailed at the uniform velocity broadcasting, and lyrics file
Carefully record the initial reproduction time of each word or word, typically only record the initial reproduction time of every lyrics, so, calculating
When the first initial time and the first end time, if all words in each lyrics of acquiescence or word are all at the uniform velocity broadcastings,
Result of calculation may have certain error with the actual initial reproduction time of easy false triggering phrase and end reproduction time, therefore,
Calculated first initial time and the first end time slightly can be adjusted, make them be more nearly easy false triggering phrase
Actual initial reproduction time and end reproduction time.Wherein, the mode of adjustment can be the setting compensation time, will be calculated
The first initial time deduct this compensation time, the first end time add this compensation time, the first initial time and first knot
The compensation time of bundle time can identical it is also possible to differ, the present embodiment is not limited to this.
Step 140, play song to be played, close sound identification module when reaching the first initial time, reach the
Start sound identification module during one end time.

Play the voice misrecognition that song leads to.
Embodiment two
Fig. 2 is a kind of flow chart of method preventing voice command misrecognition that the embodiment of the present invention two provides.This enforcement
Example is optimized based on above-described embodiment, in the present embodiment, lyrics file is optimized for Chinese lyrics file；
Default voice control command is optimized for Chinese speech control command；
Accordingly, it is optimized for searching the easy false triggering phrase in lyrics file：In the Chinese lyrics file of traversal all in
The pronunciation attribute of the civilian lyrics, wherein, pronunciation attribute at least includes tone, initial consonant and simple or compound vowel of a Chinese syllable；If in all Chinese lyrics
Each Chinese character in individual Chinese character or a Chinese phrase is all belonged to the pronunciation of the Chinese character of correspondence position in Chinese speech control command
Property is identical, then confirm that this Chinese character or Chinese phrase are identical with the language of Chinese speech control command；If in all Chinese lyrics
A Chinese character or a Chinese phrase in each Chinese character all with Chinese speech control command the Chinese character of correspondence position send out
In sound attribute at least a kind of different and at least two kinds identical, then confirm that this Chinese character or Chinese phrase control life with Chinese speech
The language of order is close；One Chinese character or a Chinese phrase are labeled as easy false triggering phrase.
Further, the first initial time and the first end that easy false triggering phrase is play will be calculated according to lyrics file
Time-optimized it is：According to lyrics file, obtain the second initial time that the lyrics sentence belonging to easy false triggering phrase plays and the
Two end times；The number of lyrics unit, easy false triggering are comprised according to the second initial time, the second end time, lyrics sentence
Phrase comprises the number and easy false triggering phrase of the lyrics unit position in lyrics sentence, calculates what easy false triggering phrase was play
First initial time and the first end time.
Further, playing song to be played, closing sound identification module when reaching the first initial time, reaching
After starting sound identification module during the first end time, can also include：Preserve easy false triggering phrase and corresponding the first
Time beginning and the first end time.
Accordingly, at the end of the first initial time and first play according to lyrics file, the easy false triggering phrase of calculating
Between before, can also include：Confirm that lyrics file does not have the easy false triggering phrase of preservation.
Accordingly, play song to be played, closing sound identification module when reaching the first initial time, reach the
Before starting sound identification module during one end time, can also include：If there is the easy false triggering phrase of preservation, reading is treated
Play easy corresponding first initial time of false triggering phrase and the first end time in song.
Accordingly, the method for the present embodiment specifically includes：
The Chinese lyrics file that step 201, acquisition are mated with song to be played.
In the present embodiment, the lyrics of song to be played are Chinese, and the lyrics file of coupling is Chinese lyrics file.
Step 202, the Chinese lyrics file of judgement whether there is the easy false triggering phrase of preservation, if not existing, execute
Step 203, if exist, execution step 209.
In the present embodiment, if play before song to be played, then will there is the easy false triggering word of preservation
Group and corresponding first initial time and the first end time, now, it is no need for searching the easy false triggering in the Chinese lyrics again
Phrase and calculate the first initial time and the first end time that easy false triggering phrase is play, can directly invoke and preserve before
Related content.
The pronunciation attribute of all Chinese lyrics in the Chinese lyrics file of step 203, traversal, wherein, pronunciation attribute at least wraps
Include tone, initial consonant and simple or compound vowel of a Chinese syllable.
In the present embodiment, if Chinese lyrics file does not have the easy false triggering phrase of preservation, be from Chinese song
Easy false triggering phrase is searched, the concrete mode searching easy false triggering phrase is each of the Chinese lyrics of traversal Chinese character in word
Pronunciation attribute, according to the matching degree of this Chinese character and the pronunciation attribute of the language of Chinese speech control command, judges that this Chinese character is
No for or whether belong to easy false triggering phrase.
Wherein, pronunciation attribute specifically refers to the property set being made up of tone, initial consonant and simple or compound vowel of a Chinese syllable etc. to the related attribute that pronounces
Close.In the Chinese lyrics pronunciation attribute of Chinese character specifically can obtain from Chinese lyrics file it is also possible to by internet from
Download in server, the present embodiment is not limited to this.
The language identical Chinese character of step 204, confirmation and Chinese speech control command or Chinese phrase, specifically, if
Each Chinese character in one of all Chinese lyrics Chinese character or a Chinese phrase is all corresponding with Chinese speech control command
The pronunciation attribute of the Chinese character of position is identical, then confirm that this Chinese character or Chinese phrase are identical with the language of Chinese speech control command.
In a specific example, when the Chinese speech control command being contrasted is "ON", in traversal Chinese song
During word file, find have in Chinese lyrics file a Chinese character pronunciation attribute identical with the pronunciation attribute of "ON" word, then general
Easy false triggering phrase confirmed as in this Chinese character in Chinese lyrics file.
In a specific example, when the Chinese speech control command being contrasted is " increase volume ", in traversal
During Chinese lyrics file, find the pronunciation attribute phase of the pronunciation attribute having a Chinese character A in Chinese lyrics file and " increasing " word
With, then continue to judge the pronunciation attribute of Chinese character A Chinese character B below whether with " plus " word is identical, if differing then it is assumed that by Chinese character
The phrase of A and Chinese character B composition is not the easy false triggering phrase of corresponding " increase volume "；If identical, continue to judge after Chinese character B
Chinese character C pronunciation attribute whether identical with the pronunciation attribute of " sound " word, if differing then it is assumed that being made up of Chinese character A, B and C
Phrase is not the easy false triggering phrase of corresponding " increase volume "；If identical, continue to judge the pronunciation of Chinese character C Chinese character D below
Whether attribute is identical with the pronunciation attribute of " measuring " word, if differing then it is assumed that the phrase being made up of Chinese character A, B, C and D is not right
Answer the easy false triggering phrase of " increase volume "；If identical then it is assumed that being corresponding " to increase sound by the phrase that Chinese character A, B, C and D form
The easy false triggering phrase of amount ".
Step 205, the confirmation Chinese character close with the language of Chinese speech control command or Chinese phrase, specifically, if
Each Chinese character in one of all Chinese lyrics Chinese character or a Chinese phrase is all corresponding with Chinese speech control command
In the pronunciation attribute of the Chinese character of position at least a kind of different and at least two kinds identical, then confirm this Chinese character or Chinese phrase with
The language of Chinese speech control command is close.
In the present embodiment, when searching the Chinese character close with the language of Chinese speech control command or Chinese phrase, only
Will in pronunciation attribute and the pronunciation attribute of Chinese character of correspondence position in Chinese speech control command of this Chinese character or Chinese phrase extremely
Rare a kind of different and at least two kinds identical, being considered as this Chinese character or Chinese phrase is easy false triggering phrase.
For example, Chinese speech control command is " turning off the light ", has two Chinese character A and B of next-door neighbour, Chinese character in the Chinese lyrics
The tone harmony parent phase of the tone of A and initial consonant and "Off" word with and Chinese character A simple or compound vowel of a Chinese syllable different with the simple or compound vowel of a Chinese syllable of "Off" word, Chinese character B's
The initial consonant of initial consonant and simple or compound vowel of a Chinese syllable and " lamp " word and simple or compound vowel of a Chinese syllable is identical and the tone of Chinese character B and the tone of " lamp " word different then it is assumed that by the Chinese
The phrase of word A and B composition is the easy false triggering phrase of corresponding " turning off the light ".
Accordingly, judge whether one of Chinese lyrics Chinese character or a Chinese phrase are the concrete of easy false triggering phrase
