Description of drawings
Fig. 1 is the present invention program's realization flow figure.
Embodiment
Below in conjunction with drawings and the specific embodiments the present invention program is described in further detail.
Referring to Fig. 1, the present invention program realizes by following steps:
Step 101, in information transmitting terminal configuration information basic element and corresponding audio information word, according to this information basic element and corresponding audio information word the audio-frequency information identification module is set at information receiving end.
Certainly, each corresponding concrete acoustic information of audio-frequency information unit also can directly be a concrete acoustic information.Such as, for transmitting terminal, its set audio-frequency information unit can directly be a sound bite; Also can be one group of measured value of the so-called acoustic feature vector that is converted to by sound bite or digital sound information, such as, the correlated frequency component information of this pairing acoustic information of audio-frequency information unit, phoneme information etc.For audio-frequency information unit is the situation of acoustic feature vector descriptor, and transmitting terminal should generate corresponding acoustic information according to this acoustic feature vector descriptor, specifically can be by realizations such as sound generators.
Identification for ease of information receiving end acoustic information identification module, audio frequency can also further be set isolate symbol, this audio frequency is set between per two audio-frequency information units isolates symbol, after making that information transmitting terminal whenever sends a pairing acoustic information of audio-frequency information unit, just send an audio frequency and isolate symbol, send the pairing acoustic information of next audio-frequency information unit afterwards again.When information receiving end carries out audio identification, reject the audio frequency that is mixed in wherein automatically and isolate symbol.
In the information receiving end, can from the acoustic information that receives, identify corresponding information basic element according to information basic element and the set audio-frequency information identification module of corresponding audio information word.Specifically, owing to corresponding acoustic pattern can be set at each audio-frequency information unit, and in the ordinary course of things, the acoustic pattern of an audio-frequency information unit can be the scope of associated description value of the acoustic feature vector of the pairing acoustic information of this audio-frequency information unit, therefore the database that includes each pairing acoustic pattern of audio-frequency information unit can be set, be called for short the acoustic pattern storehouse.Like this, the audio-frequency information identification module of receiving terminal is after receiving the acoustic information that transmitting terminal sends, mate with the acoustic pattern in this acoustic information and the acoustic pattern storehouse, the acoustic pattern of selecting maximum coupling is as matching result, and with the pairing information basic element of this acoustic pattern as information basic element to be determined.
Specifically, the acoustic information identification module in the information receiving end at first will extract one section acoustic information from the acoustic information that information transmitting terminal is sent, and regards this section acoustic information that is extracted as with audio-frequency information unit corresponding acoustic information.Certainly, under the situation that is provided with audio frequency isolation symbol, isolate the acoustic information that symbol then can directly be determined and audio-frequency information unit is corresponding according to audio frequency.After the acoustic information of determining corresponding to an audio-frequency information unit, can measure one group of acoustic feature vector value of this acoustic information earlier, then, mate according to all acoustic patterns in this group measured value and the acoustic pattern storehouse, and with the maximum pairing information basic element of acoustic pattern of this group measured value that mated in the acoustic pattern storehouse as the first pairing information basic element of audio-frequency information.If audio-frequency information unit is the descriptor of acoustic feature vector, then the pairing acoustic pattern of audio-frequency information unit can directly be the scope of the associated description value of this acoustic feature vector, also can be the scope of associated description value of the acoustic feature vector of the corresponding sound information that generated according to this acoustic feature vector descriptor.Wherein, can the corresponding relation of acoustic pattern and information basic element directly be set at information receiving end according to the corresponding relation of information basic element and audio-frequency information unit.Like this, information receiving end can be determined corresponding information basic element according to this corresponding relation determined corresponding maximum coupling acoustic pattern according to the acoustic information that receives after.
When the acoustic information that extracts from acoustic information fails to match effectively acoustic pattern in the acoustic pattern storehouse, the acoustic information that this extraction is described does not have and its corresponding audio information word, at this moment can extract one section acoustic information again from acoustic information and handle accordingly.
In a word, can determine corresponding acoustic pattern, and come audio-frequency information identification module in the configuration information receiving terminal according to this acoustic pattern and information basic element according to information basic element corresponding audio information word.Like this, receiving terminal is behind the acoustic information that receives the transmitting terminal transmission, corresponding acoustic information is converted to the acoustic feature vector descriptor, and remove to mate corresponding acoustic pattern according to this acoustic feature vector descriptor, thereby the audio-frequency information identification module can identify the information basic element according to the acoustic pattern of maximum possible coupling from the audio-frequency information that receives.
Because speech recognition technology is a known technology, so this voice recognition technology itself is not done too much description.The present invention mainly is to use speech recognition technology to finish the identification of the acoustic information that receiving terminal sends transmitting terminal, wanted information transmitted to obtain transmitting terminal, thereby realize with acoustic information as carrying, by the transmission of speech channel, also promptly realize the transmission of non-acoustic information by speech channel to non-acoustic information.
After step 102～104, information transmitting terminal and information receiving end are set up speech channel, when needs send information, obtain information basic element sequence according to this information, and according to the corresponding relation of information basic element and audio-frequency information unit, determine pairing all the audio-frequency information units of this information basic element sequence, by the speech channel of having set up these pairing acoustic informations of audio-frequency information unit are sent to receiving terminal more afterwards.
The information basic element can be " 0 " and " 1 " of binary-coded character, in this case, if wish to send letter " A ", and the ascii character value of " A " is " 41 " of 16 systems, then transmitting terminal can be decomposed into " A " information basic element sequence " 01000001 ", like this, just can determine corresponding audio-frequency information unit according to this information basic element sequence.That is to say, after being provided with " 0 " and " 1 " difference corresponding audio information word, just can determine information basic element sequence corresponding audio information word, by the speech channel of having set up these pairing acoustic informations of audio-frequency information unit be sent to information receiving end afterwards according to this corresponding relation.
If set audio-frequency information metamessage is a sound bite, then transmitting terminal can directly send the digital sound information of this sound bite, certainly, and for the situation of analog communication, then can be to play-over this sound bite, also promptly transmit the analoging sound signal of sound bite.
If set audio-frequency information unit is the descriptor of the acoustic feature vector that is converted to by acoustic informations such as sound bites, then information transmitting terminal can produce the acoustic information of an analog voice fragment according to this descriptor, and the acoustic information of this analog voice fragment is sent to receiving terminal.
Here, information basic element sequence can directly be the information that will transmit, such as, when using numerical character that " 0 " arrive " 9 " as the information basic element, information basic element sequence " 88115066 " can directly be a telephone number information that will transmit.
By above-mentioned steps, can realize purpose of the present invention.
In fact the related audio-frequency information unit of the present invention program can be audio signal, and the pairing information of this audio signal both can be the voice messaging such as voice document, also can be the music information such as music file.If wishing the information of an audio signal correspondence is voice messaging, can this audio-frequency information unit be set to corresponding sound bite.
Obviously, above-mentioned information transmitting terminal and information receiving end can be all telephone terminals that comprise portable terminal and fixed terminal, can also be other network side communication apparatus.That is to say,,, just can realize information interaction by this speech channel as long as communicating pair can be set up speech channel by the present invention program's setting.
The information basic element that said process is carried can be the key information of communication terminal, certainly, also can be other information.With the key information is example, such as, each key number is represented this digital original meaning, also is that the pairing key information of each key number is exactly the information basic element, and the pairing audio-frequency information of each key information basic element unit is set.Like this, information transmitting terminal user is need be when information receiving end sends the digital information of telephone number and so on, can generate the information basic element by the input key information, information transmitting terminal is after the information of receiving by the button input, this information is correspondingly processed again, thereby the corresponding audio-frequency information of the key information that obtains and import unit then sends to information receiving end with the pairing acoustic information of audio-frequency information unit.Information receiving end then identifies the information basic element by the audio-frequency information identification module from the acoustic information of receiving, because the information basic element is key information, therefore, the information basic element of obtaining is and obtains key information, the telephone number that also just obtains information transmitting terminal and sent.Equally, can transmit out of Memory to information receiving end from information transmitting terminal in this way, such as, directory number, and information receiving end require input such as information such as access pins.
According to button configuration information basic element the time, can also do further setting.Such as, the information basic element of clicking certain button representative can be set, the information basic element of certain button representative of rapid double tap, pin the information basic element of the motionless representative of certain button for a long time, or the information basic element of the combination representative of a plurality of buttons or the like, and the pairing audio-frequency information of these special key information basic elements unit is set.Certainly, also need the audio-frequency information identification module in the information receiving end is made corresponding setting, make it can identify these special information basic elements.
The information basic element can also be set to ascii character, correspondingly, the pairing audio-frequency information of each ascii character unit should be set.In this way, information transmitting terminal then can send to information receiving end with an email address quickly.
Certainly, as previously mentioned, the information basic element can also be set to binary-coded character, and binary-coded character includes only " 0 " and " 1 ", and therefore, the pairing audio-frequency information of configuration information basic element unit is and establishes reset and " 1 " pairing audio-frequency information unit.Owing to can express any information by " 0 " and " 1 ", therefore, in this way, information transmitting terminal can send any information to information receiving end.In this case, the audio identification module of information receiving end is also wanted to identify " 0 " and " 1 " two essential information elements.
In addition, the present invention can also be provided for the start information element of expression information transmission beginning and begin audio-frequency information unit accordingly.Information transmitting terminal at first usually sent the pairing acoustic information of beginning audio-frequency information unit according to start information unit before sending information word, then send by the pairing acoustic information of audio-frequency information unit that will transmission information obtains; Correspondingly, at information receiving end the two-stage recognition function is set, when information receiving end after setting up conversation with information transmitting terminal, at first start the primary characterization function, the start information basic element whether occurred in the acoustic information that monitoring is received, when detecting the start information basic element, begin to start the secondary characterization function, the follow-up acoustic information that receives is carried out secondary characterization, thereby obtain the pairing information basic element of information that will send, and then obtain the information that will send.
Here, because the information basic element that the primary characterization function is discerned only comprises the start information basic element, so recognition efficiency can be higher, thereby aligning the voice communication of often being undertaken by this speech channel influences less.Because the secondary characterization function wants the identifying information basic element to comprise all possible information basic element, these information basic element collection may be bigger, and therefore, when carrying out the speech pattern coupling, the efficient of processing can be than at the bottom of the primary characterization.Certainly, also can suitably enlarge the quantity of the information basic element that the primary characterization function discerned, thereby realize that information transmitting terminal carries out comparatively complicated controlled function to information receiving end.Such as, receiving terminal can have different RMs, and transmitting terminal can pass through control command, and the indication receiving terminal starts corresponding RM.
In the middle of the reality, can obtain beginning audio-frequency information unit by audio fragment of intercepting in the special cry of certain animal, such as, the sound clip that some mankind of intercepting are difficult to imitate from the tediously long cry of jackass.Certainly, also can from the special cry of some animals, intercept some audio fragments and obtain other audio-frequency information unit.
Correspondingly, can also be provided for expression information and send ending message element and the corresponding audio-frequency information unit that finishes that finishes.Information transmitting terminal usually sends the pairing acoustic information of end audio-frequency information unit according to ending message unit when finishing transmission information, information receiving end then finishes the secondary characterization function when recognizing reception information basic element.Certainly, after the end secondary characterization function, identification module can come back to the primary characterization state.
The above only is the present invention program's preferred embodiment, not in order to limit protection scope of the present invention.
