Hand, title of the song and special edition.
It is preferred that, it is described corresponding music searching is carried out according to the search keyword and its type after, in addition to：
Search result is screened according to matching degree, playback volume and tonequality；
Optimal the selection result is played out.
It is preferred that, before the voice of the acquisition user input, in addition to：
Set up regular expression database.
A kind of device of phonetic search music, including：
Voice acquiring unit, the voice for obtaining user's input；
Voice recognition unit, sentence is obtained for the voice to be identified；
Matching unit, for matching regular expressions corresponding with the sentence from default regular expression database
Formula；
Comparing unit, for contrasting the sentence and the regular expression, obtains search keyword；
Music searching unit, it is described to search for carrying out corresponding music searching according to the search keyword and its type
The type of rope keyword includes singer, title of the song and special edition.
It is preferred that, described device also includes：
Screening unit, for it is described corresponding music searching is carried out according to the search keyword and its type after, root
Search result is screened according to matching degree, playback volume and tonequality；
Automatic broadcast unit, for optimal the selection result to be played out.
It is preferred that, described device also includes：
Database Unit, for before the voice of the acquisition user input, setting up regular expression database.
Compared with prior art, technical scheme has advantages below：
The method and device for a kind of phonetic search music that above-mentioned technical proposal is provided, from default regular expression data
Matching obtains regular expression corresponding with the sentence recognized, contrast sentence and regular expression in storehouse, obtains search crucial
Word, music searching is carried out using search keyword and its type.For different types of search keyword, different search is carried out
Rope, such as, for the search keyword of title of the song type, search for title of the song, effectively increase the precision of music searching result.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
A kind of method of phonetic search music is present embodiments provided, referring to Fig. 1, this method can include：
Step S11：Obtain the voice of user's input；
Step S12：The voice is identified and obtains sentence；
Speech recognition technology is the technology of comparative maturity, for example the winged speech engine of University of Science and Technology's news, exposes corresponding interface,
Speech-recognition services are provided for all APP (Application, computer applied algorithm), the speech engine is utilized, it is possible to achieve
Good speech recognition.
Step S13：Matching obtains regular expression corresponding with the sentence from default regular expression database；
Regular expression is a kind of special character string mode, for matching one group of character string, is produced like with grinding tool
Product, regular expression is exactly this grinding tool, defines a kind of rule and goes to match legal character." * " in regular expression
General matching symbol is represented, any character of any number can be matched, such as " I wants to listen * " to match, and " I wants to listen small apple
Really ", " I wants to listen Chengdu ", " I wants to listen blue and white porcelain " etc.., can be from canonical when the sentence recognized is " I wants to listen griggles "
Regular expression is matched in expression formula database, and " I wants to listen * ".
Step S14：The sentence and the regular expression are contrasted, search keyword is obtained；
Character string corresponding with " * " in regular expression is search keyword in sentence.
Step S15：Music searching, the type of the search keyword are carried out according to the search keyword and its type
Including singer, title of the song and special edition.
By the way that " I wants to listen * ", " I wants to listen * * ", " play * ", " regular expression and the corresponding sentence pair such as search * "
Than what is obtained is the search keyword of title of the song type.Pass through the canonical such as " I wants to listen * song ", " song for playing * ", " * song "
Expression formula is contrasted with corresponding sentence, and what is obtained is the search keyword of singer's type.By " playing special edition * ", " playing *'s
What the regular expressions such as special edition * " were obtained is the search keyword of special edition type.For the search keyword of title of the song type, carry out
Title of the song is searched for；For the search keyword of singer's type, singer's search is carried out；For the search keyword of special edition type, carry out
Special edition is searched for.
The present embodiment provide phonetic search music method, from default regular expression database matching obtain with
The corresponding regular expression of sentence recognized, contrast sentence and regular expression, obtain search keyword, crucial using search
Word and its type carry out music searching.For different types of search keyword, different search are carried out, music is effectively increased
The precision of search result.
A kind of method of phonetic search music is present embodiments provided, referring to Fig. 2, this method can include：
Step S21：Obtain the voice of user's input；
Step S22：The voice is identified and obtains sentence；
Step S23：Matching obtains regular expression corresponding with the sentence from default regular expression database；
Step S24：The sentence and the regular expression are contrasted, search keyword is obtained；
Step S25：Music searching, the type of the search keyword are carried out according to the search keyword and its type
Including singer, title of the song and special edition.
Step S26：Search result is screened according to matching degree, playback volume and tonequality；
Step S27：Optimal the selection result is played out.
Can the weight different to the setting of matching degree, playback volume and tonequality respectively, search result is ranked up, selection is most
Excellent the selection result is played out.
By the filtering to search result, the degree of accuracy of search result is further increased.
Before the voice of user's input is obtained, in addition to：Set up regular expression database.Regular expression database bag
