In order to the scheme making those skilled in the art person understand the embodiment of the present invention better, below in conjunction with the detailed description that drawings and embodiments are further described the embodiment of the present invention.
Refer to Fig. 1, the process flow diagram of its instant push-to-talk service control method embodiment 1 disclosed for the embodiment of the present invention, the method comprises:
Step 101, receives voice, the phonetic feature that the voice that parsing receives have.
In actual applications, user can use multiple different terminal device such as: smart mobile phone, intercom, dispatching desk etc., these terminals have physics PTT button or software PTT button, Prepaid & Postpaid Telephony Service can be supported, simultaneously, these terminal devices all have the function receiving voice, no matter which type of environment user is in, equipment all can receive voice.Only for intercom, the present embodiment is explained below.
When user is when being busy with one's work both hands inconvenience, hand cannot be extracted out and press PTT button to trigger PTT service always, user only needs by Voice command, if control by means of only the sound size of voice, easy generation maloperation, such as: user at one's side other people due to the excessive and PTT service of activated user equipment of noise that spoken sounds is excessive or extraneous, thus cause maloperation frequently to occur.According to control statement fairly simple, such as: the control statement preset is " beginning ", when user or people at one's side unconsciously tell " beginning " this word in talk, will the PTT service of trigger equipment, maloperation equally also can be caused frequently to occur.According to control statement more complicated, user is difficult to remember, usually in use, cannot proper operation, or after control statement known by other people, also easily produce maloperation.
In order to ensure the proper operation of user to equipment PTT service, the present embodiment utilizes the phonetic feature of user to trigger PTT service, because everyone phonetic feature is all not identical, even if the voice size of two people is identical, the statement of expressing is identical, also can not affect the phonetic feature of individual.
So-called phonetic feature can be embodied by the main characteristic parameters of voice, and these speech characteristic parameters can comprise: frequency, bandwidth, amplitude, fundamental frequency, average energy, par are across the remainder or across parameters such as zero rate, resonance peak, LP parameter cepstrum parameter, critical band cepstrums; Can be realized by multiple different algorithm the phonetic feature analysis of voice, such as: linear prediction analysis LPC method etc.
The situation of assembling owing to often having intercom user in daily use occurs, for a certain user, when he is when using the intercom of oneself, he is by Voice command intercom, easily be subject to the interference of other sound such as user voice or outside noise, in order to reduce or eliminate interference, intercom is after the voice receiving user, filtration treatment can be carried out, the voice of user are as far as possible intactly extracted from all sound received, then, recycling phonetic feature analytical approach parses the phonetic feature of these voice, the phonetic feature parsed is that technical foundation is accomplished fluently in the triggering of follow-up PTT service.
Step 102, searches whether there is resolved phonetic feature in the phonetic feature preserved in advance, and the described phonetic feature preserved in advance gathers in advance and the phonetic feature that has of user that allows of the equipment preserved.If exist, then perform step 103, trigger instant push-to-talk business.
In order to ensure the accuracy of user's trigger equipment PTT service, needing the phonetic feature preserving user in advance, if when this equipment only allows a people to use, then only needing to gather in advance the phonetic feature of this user and being preserved.If when this equipment can allow multiple people to use, then need to gather in advance the phonetic feature of admissible multiple user and it is all preserved.For equipment, when user uses this equipment first time, the phonetic feature that equipment can extract user is automatically preserved, and when user uses next time, voice characteristics information can be utilized to trigger PTT service.For user, want to trigger PTT service by the mode of phonetic feature, must in advance by the voice characteristics information recording device of oneself.
For equipment, when receiving the voice messaging of user, parse phonetic feature, then just need from the phonetic feature preserved in advance, search whether there is current resolved phonetic feature, if existed, show that the Voice command of active user is effectively executable, therefore, trigger PTT service.If there is no, show that the Voice command of active user is invalid not executable, therefore, ignore and do not process, to avoid maloperation.
Can be found out by the invention described above embodiment, using the phonetic feature of user as the judgment standard whether triggering PTT service, the interference of other user speech or outside noise can be avoided like this and the maloperation produced, thus accurately control instant push-to-talk business, improve the experience of user.
In actual applications, when multiple user flocks together or when external interference sound is larger, for equipment, do not know which sound is the sound of the user that this equipment allows, which is the sound of other users, and which is noise, as long as receive voice, all first will carry out parsing phonetic feature, then from the phonetic feature preserved in advance, search whether there is resolved phonetic feature, if existed, then trigger PTT service, if the user of a certain equipment does not sound, do not want to trigger PTT service, and other people sound is excessive at one's side, the equipment of this user still can receive these sound, carry out a series of operation, will serious waste device resource.Based on the consideration of above-mentioned technical matters, the embodiment of the present invention provides following three preferred versions, is embodiment 2,3 and embodiment 4 respectively.Successively these three preferred versions are explained below.

After such process, only have user oneself to know default control statement, other users do not know this control statement, even if sound also cannot to this equipment generation effect for other users.Therefore, can first judge to receive the triggering statement that voice are PTT service by this step, if not, just need not carry out follow-up parsing phonetic feature again, search the operations such as phonetic feature, this makes it possible to avoid wasting device resource.In addition, even if when the control statement of this equipment is known by other users and says, by follow-up search operation, can also make and judging more accurately, thus avoid maloperation.
Certainly, also can be after reception voice, first identify in the voice received whether there is default control statement, the phonetic feature that the voice that if so, then parsing receives have, then, then perform step 303.Otherwise, do not carry out parse operation, search operation.After can avoiding receiving voice like this, directly carry out parse operation, then, carry out identifying operation again, if recognition result is no, follow-up needs performs search operation, cause resolved phonetic feature without any value, and parse operation compares consumes resources, therefore, process further can save device resource like this.
Step 303, searches whether there is resolved phonetic feature in the phonetic feature preserved in advance, and the described phonetic feature preserved in advance gathers in advance and the phonetic feature that has of user that allows of the equipment preserved; If exist, perform step 304.
Step 304, triggers instant push-to-talk business.
Can be found out by the invention described above embodiment, utilize the method that whether there is default control statement in the voice identifying and receive, control whether to carry out search operation, the appearance of the wasting of resources phenomenon that unnecessary search operation can either be avoided like this to cause, can improve again the reliability triggering PTT service.
Finally, refer to Fig. 4, the process flow diagram of the embodiment of the present invention illustrated instant push-to-talk service control method embodiment 4, the method comprises:
Step 401, receives voice, the phonetic feature that the voice that parsing receives have;
Step 402, judges whether the volume of the voice received is greater than predetermined threshold value, if be greater than, then performs step 403;
Step 403, identifies in the voice received whether there is default control statement, if exist, then performs step 404;
Certainly, also can be after reception voice, first judge whether the volume of the voice received is greater than predetermined threshold value, if be greater than, then identify in the voice received whether there is default control statement, if exist, the phonetic feature that the voice that then parsing receives have, then performs step 404; Otherwise, do not carry out parse operation, search operation.
Step 404, searches whether there is resolved phonetic feature in the phonetic feature preserved in advance, and the described phonetic feature preserved in advance gathers in advance and the phonetic feature that has of user that allows of the equipment preserved; If exist, perform step 405.
Step 405, triggers instant push-to-talk business.
All can be found out by above-mentioned three preferred versions, by judging whether the volume of voice received exists default control statement in whether being greater than predetermined threshold value and identifying the voice that receive, two operations further ensure the reliability of follow-up search operation, avoid unnecessary search operation waste device resource.
