Intelligent sound recorded broadcast device and methodTechnical field
The present invention relates to portable audiovisual apparatus field, in particular to a kind of device and method utilizing line control earphone Mike to carry out intelligent sound recorded broadcast.
Background technology
At present, smart mobile phone is listened to the music and is seen that video has become homely food, brings earphone that user can be made to obtain better audio and experiences. But often can run into such situation: the audio frequency oneself being just immersed in earphone to play, has suddenly people oneself to be spoken, fail not hear the language of the other side owing to the sound in earphone is relatively big, have to take earphone, and trouble allows the other side heavily give an account of. This results in some occasion and remove the loaded down with trivial details of earphone, the other side may because needing to repeat to speak and feel bored in addition.
The patent No. be 201420361776.1 Chinese utility model patent disclose " a kind of exempting from extracts the earphone carrying out low coverage dialogue ", this earphone comprises earphone case, sound source input end and power amplifier, also comprise full directional microphone, operational amplifier, first analog to digital converter, filtering circuit and hybrid circuit, the output terminal of full directional microphone is connected with the input terminus of operational amplifier, the output terminal of operational amplifier is connected with the input terminus of the first analog to digital converter, the output terminal of the first analog to digital converter is connected with the input terminus of filtering circuit, the output terminal of filtering circuit is connected with the first input terminus of hybrid circuit, sound source input end is connected with the 2nd input terminus of hybrid circuit, the output terminal of hybrid circuit is connected with the input terminus of power amplifier. earphone arranges full directional microphone, full directional microphone gathers the speech signal around earphone, after being undertaken speech signal filtering, the voice signal that inputs with the sound source of earphone is mixed and is exported from loudspeaker by power amplifier, user need not extract earphone can carry out low coverage dialogue with neighbouring people, it may also be useful to convenient. but this earphone realizes the operation such as voice collecting, filtration by pure hardware circuit, sound source mixing that is last and earphone itself exports. what user heard when wear headphones listens audio frequency will be the mixing that earphone sound source adds the surrounding environment sound after this earphone filters, and user cannot remove the ambient sound not needed voluntarily, affect the effect experience that user listens to the music.
Summary of the invention
It is an object of the invention to solve when adopting the audio frequency that portable audiovisual equipment listened to by earphone at present, run into others and oneself speak not easily that the very first time is caught, it is necessary to extract earphone again with the other side's communication, cause the technical problem of poor user experience.
For realizing above goal of the invention, on the one hand, the present invention provides a kind of intelligent sound recorded broadcast device, comprise intelligent mobile terminal and line control earphone Mike, described intelligent mobile terminal comprises speech recognition module, voice recording module and speech play module, described intelligent mobile terminal is provided with earphone jack, and described line control earphone Mike is provided with broadcasting button;
When described line control earphone Mike inserts described earphone jack, described speech recognition module identifies the speech signal filtered out in the surrounding environment sound by described line control earphone Mike collection automatically, and described speech signal is delivered to described voice recording module and carries out recording and preserving;
When pressing described broadcasting button, play nearest one section of described speech signal recorded by described speech play module, and send user to by described line control earphone Mike.
Further, in described intelligent mobile terminal, also being provided with recording switch in the front end of described speech recognition module, when opening described recording switch, described speech recognition module just identifies that screening is by the speech signal in the surrounding environment sound of described line control earphone Mike collection automatically.
Further, only when described speech signal continuous for some time t, and when reaching certain loudness, just start described voice recording module and record.
Further, described time t >=5 second.
Further, described speech recognition module identifies described speech signal wherein according to the range of frequency of described ambient sound, if the range of frequency of described ambient sound is in the range of frequency of voice, then described ambient sound is identified as speech signal.
Further, when pressing described broadcasting button, the sound signal play in intelligent mobile terminal described in automatic pause or the volume automatically reducing described sound signal, so that user clearly listens to the described speech signal recorded.
Further, when the described speech signal recorded also is not play after T after a while, then automatically delete described speech signal.
Further, described time T >=1 minute.
Further, described intelligent mobile terminal is mobile phone or panel computer.
On the other hand, the present invention provides a kind of intelligent sound recorded broadcast method, comprises the steps:
(1) intelligent mobile terminal and line control earphone Mike is provided, described intelligent mobile terminal comprises speech recognition module, voice recording module and speech play module, described intelligent mobile terminal arranges earphone jack, described line control earphone Mike arranges broadcasting button;
(2) described line control earphone Mike is inserted described earphone jack, then described speech recognition module identifies the speech signal filtered out in the surrounding environment sound by described line control earphone Mike collection automatically, and described speech signal is delivered to described voice recording module and carries out recording and preserving;
(3) press described broadcasting button, then described speech play module plays nearest one section of described speech signal recorded, and sends user to by described line control earphone Mike.
Further, in described intelligent mobile terminal, also arranging recording switch in the front end of described speech recognition module, when opening described recording switch, described speech recognition module just identifies the speech signal filtered out in the surrounding environment sound by described line control earphone Mike collection automatically.
Further, only when described speech signal continuous for some time t, and when reaching certain loudness, just start described voice recording module and record.
Further, when pressing described broadcasting button, the sound signal play in intelligent mobile terminal described in automatic pause or the volume automatically reducing described sound signal, so that user clearly listens to the described speech signal recorded.
Further, described speech recognition module identifies described speech signal wherein according to the range of frequency of described ambient sound, if the range of frequency of described ambient sound is in the range of frequency of voice, then described ambient sound is identified as speech signal.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention adopts the line control earphone of common band Mike, from surrounding environment sound, recognize one section of continuous print voice by the speech recognition module in intelligent mobile terminal and undertaken recording and preserving by voice recording module, user can be play by the press key shortcut on line control earphone according to oneself needing, do not need, can comprehend, the effect experience that user normally listens to the music can not be had influence on. It spirit is a kind of software solution, without the need to extra hardware, cost is low, it is applicable to any intelligent terminal, the troublesome operation that user extracts earphone can be removed from, only need to press the button on line control earphone, the other side and the voice oneself spoken just now can be heard in earphone, convenient and swift, and the audio mix that ambient sound can not play in real time and currently, do not affect the normal audio of user and experience.
