Description
Technical field
The present invention relates to a kind of method that realizes voice broadcast based on the soft kernel of TD platform.
Background technology
Since the communicating terminal voice broadcast function is realized, bring great convenience to people's life, as: voice broadcasting of short messages, calling voice report etc.But because the method that the existing techniques in realizing voice broadcast is handled, the general employing " hard kernel " encoding and decoding technique, soon speech data will be synthetic directly is embedded in the hardware with the voice broadcast program, this method not only takies a large amount of internal memories, and increased the cost of end product, changed the circuit of end product, also be difficult for later maintenance, in addition, if foundries changes its technological parameter or built-in function, may operate as normal along with the hard kernel of the change of technology, this has just produced certain risk.
Summary of the invention
The invention provides and a kind ofly realize the method for voice broadcast based on the soft kernel of TD platform, having overcome the existing voice broadcast implementation method of background technology increases the hardware cost and the deficiency of easy care not.
A kind ofly realize the method for voice broadcast based on the soft kernel of TD platform, it is characterized in that: it comprises:
Step 10 is imported the primary voice data that will report into;
Step 20 sends synthesized voice signal, starts the phonetic synthesis thread, and the beginning speech data is synthetic;
Step 30 is inserted the broadcast formation with synthetic data;
Step 40, the soft kernel of speech play of startup TD platform begins to play voice;
Step 50 finishes speech play;
In one preferred embodiment, this step 30 also comprises:
Step 31, the synthetic speech data;
Step 32 is prescribed a time limit when synthetic amount of voice data reaches on certain buffer memory, sends block signal, activates and blocks thread;
In one preferred embodiment, this step 40 also comprises:
Step 41 is judged the speech data surplus of playing in the formation, when reaching under certain buffer memory, the speech data surplus of playing formation prescribes a time limit, and execution in step 42, otherwise continue execution in step 40;
Step 42, transmission stops block signal, stops to block thread, starts the phonetic synthesis thread, and it is synthetic to proceed speech data, changes and jumps execution in step 20;
In one preferred embodiment, described voice broadcast can carry out repeatedly broadcasting by the parameter setting, time-delay is reported and the setting of men and women's sound.
In one preferred embodiment, the method that its repeatedly broadcasting and time-delay are reported comprises:
Step 100, the beginning speech play;
Step 200, broadcasting time adds one;
Whether step 300 judges broadcasting time greater than the broadcast total degree that is provided with, and execution in step 400 if not, otherwise execution in step 700;
Step 400 judges whether to be provided with time-delay and reports, if execution in step 500, otherwise execution in step 100;
Step 500, trigger;
Step 600 judges whether the time of time-delay arrives, if execution in step 100, otherwise execution in step 500;
Step 700 finishes speech play;
The technical program is compared with background technology: owing to the present invention is based on the soft kernel of TD platform, adopt thread block method realization voice to report continuously, therefore it to have overcome background technology not enoughly and have following advantage existing: 1, can realize voice broadcast owing to only need to revise software, need not to carry out the modification of terminating circuit design, can reduce the end product cost; 2, because phonetic synthesis and voice broadcast have made full use of buffer memory, can improve running efficiency of system, reduce the relevant issues that cause because of the buffer memory deficiency; 3, the present invention to system require lowly, adaptability is strong.

Embodiment
A kind ofly realize the method for voice broadcast, please refer to Fig. 1 and Fig. 2 based on the soft kernel of TD platform, the realization voice broadcast of a preferred embodiment and the graph of a relation of phonetic synthesis and voice broadcast process flow diagram, it comprises this method:
Step 10 is imported the primary voice data that will report into;
Step 20 sends synthesized voice signal, starts the phonetic synthesis thread, and the beginning speech data is synthetic;
Step 30 is inserted synthetic speech data in the broadcast formation;
Step 31, the synthetic speech data;
Step 32 is prescribed a time limit when synthetic amount of voice data reaches on certain buffer memory, sends block signal, activates and blocks thread; For example, in the preferred embodiment, be limited to 10K on this synthetic speech data volume buffer memory,, activate and block thread when synthetic amount of voice data during greater than 10K.
Step 40, the soft kernel of speech play of startup TD platform begins to play voice;
Step 41 is judged the speech data surplus of playing in the formation, when reaching under certain buffer memory, the speech data surplus of playing formation prescribes a time limit, and execution in step 42, otherwise continue execution in step 40;
Step 42, transmission stops block signal, stops to block thread, starts the phonetic synthesis thread, and it is synthetic to proceed speech data, changes and jumps execution in step 20; For example, in the preferred embodiment, be limited to 1K under this broadcast formation amount of voice data buffer memory, when amount of voice data only is left 1K in playing formation, stop to block thread, start the phonetic synthesis thread, it is synthetic to proceed speech data.Step 50 finishes speech play;
In this step 20, when the generated data total length equates with the played data total length, will jump to step 50, finish speech play.In the embodiment of the invention, the cache size of generated data adds this time generated data length for the generated data total length, plays cache size and plays data cached length for the played data total length adds this time.
The present invention passes through the method synthetic speech data of thread block, and by controlling synthetic and reporting required buffer memory and use, has realized the continuous report of voice, has improved running efficiency of system.
Implementation method of the present invention, the user can also realize repeatedly repeatedly broadcasting by being provided with, and also can realize the time-delay report between twice report by parameter is set, also can enable male sound or women sound by setting, please refer to Fig. 3, the repetition voice broadcast of one preferred embodiment and time-delay voice broadcast process flow diagram, its method comprises as follows:
Step 100, the beginning speech play;
Step 200 is provided with broadcasting time and adds one;
Whether step 300 judges broadcasting time greater than the broadcast total degree that is provided with, and execution in step 400 if not, otherwise execution in step 700;
Step 400 judges whether to be provided with time-delay and reports, if execution in step 500, otherwise execution in step 100;
Step 500, trigger;
Step 600 judges whether the time of time-delay arrives, if execution in step 100, otherwise execution in step 500;
Step 700 finishes speech play;
The above, only for preferred embodiment of the present invention, so can not limit scope of the invention process with this, i.e. the equivalence of doing according to the present patent application claim and description changes and modification, all should still belong in the scope that patent of the present invention contains.
