Description
Technical field
The present invention is a speech data IP communication transmission technology, belongs to the voice communication technical field.
Background technology
In present speech data IP communication transmission technology, what adopt is to encode the voice transmitting terminal is taken a sample digitized processing to voice signal after, be transferred to receiving terminal according to the IP host-host protocol and decode, again speech data signal is reduced into the transmission and processing process of voice analog signal; Because voice signal is a continuity real-time process signal, and in the IP transmission course, have packet inhomogeneous time-delay in transmission course, Data Receiving speed is non-constant or the phenomenon of data-bag lost, therefore have and cause the fidelity of speech data in the IP transmission and the possibility of the property understood decline, so the voice over IP transmission technology is necessary to do some improvement work.
Summary of the invention
In view of the foregoing, the object of the present invention is to provide a kind of voice data transmission processing method and voice data transmission processor, can be at the inhomogeneous time-delay that in the IP transmission course, occurs at speech data, Data Receiving speed is non-constant or the data-bag lost problem is revised, and improves fidelity and the understanding property of speech data in the IP transmission course.
For achieving the above object, the present invention introduces a kind of voice data transmission processing method and voice data transmission processor of being realized by speech digit processor, voice data transmission system, microprocessor and software etc., it is characterized in that adopting following voice data transmission work of treatment method:
(1) sets speech syllable initial code time of reception parameter and speech syllable stop code time of reception parameter;
(2) the phonetic sampling speed of current speech digitized processing is encoded obtain the phonetic sampling rate code;
(3) starting point to the speech syllable of speech data is provided with the speech syllable initial code in phonetic coding is handled, terminating point at speech syllable is provided with the speech syllable stop code, each speech data is provided with the speech-sound data sequence sign indicating number sequentially, each syllable is provided with the speech syllable sequence code sequentially;
(4) speech syllable initial code, speech syllable stop code, speech data, speech-sound data sequence sign indicating number, speech syllable sequence code and current speech sampling rate sign indicating number are sent to receiving terminal;
(5) receiving terminal according to speech data between the speech syllable initial code, speech syllable stop code, speech syllable initial code and the speech syllable stop code that receive and current phonetic sampling rate code after, order that speech syllable initial code with same voice syllable sequence number and the speech data between the speech syllable stop code are indicated according to the speech-sound data sequence sign indicating number and the current pairing phonetic sampling speed of phonetic sampling rate code are carried out voice recovery processing;
(6) the speech data receiving terminal obtains allowing to receive the voice rate sign indicating number with current language data receiving velocity coding, and should allow reception voice rate sign indicating number to be sent to the speech data transmitting terminal, the speech data transmitting terminal allows to receive the sampling rate that voice rate sign indicating number is set the current speech digitized processing according to this;
(7) when speech data and speech-sound data sequence sign indicating number thereof are lost in transmission, it is the voice lines type function of variable that the pairing amplitude-frequency value of being received before and after the speech-sound data sequence sign indicating number of receiving terminal according to the speech data sign indicating number of losing of speech data is set up with the speech-sound data sequence sign indicating number, with the value of the speech-sound data sequence sign indicating number of losing the speech data correspondence, join in the corresponding sequence of speech data sign indicating number of reception as the speech data sign indicating number of repairing after drawing pairing amplitude-frequency value and give digitlization by the voice lines type function;
(8) when speech syllable initial code time of reception parameter is not received the speech syllable initial code in specified time, be judged to be when then finishing and receive the speech syllable initial code with the specified time of speech syllable initial code time of reception parameter, from receiving the speech syllable initial code, when speech syllable stop code time of reception parameter is not received the speech syllable stop code in specified time, be judged to be when then finishing and receive the speech syllable stop code with the specified time of speech syllable stop code time of reception parameter, when not receiving the speech syllable sequence code, the preceding speech syllable sequence code of once receiving is given behind the increasing or decreasing as current speech syllable sequence code, when not receiving the phonetic sampling rate code, with the preceding phonetic sampling rate code of once receiving as current phonetic sampling rate code.
Operation principle of the present invention is: in the IP of voice signal transmission course, adopted being stored after the speech data reception, and by identification to speech syllable, be respectively arranged with speech syllable initial code and speech syllable stop code before and after the complete speech data to each speech syllable, judge by reception speech syllable initial code and speech syllable stop code, confirm each syllable data receive whole after, according to the sampling rate in the voice digitization processing procedure speech data is recovered, then can eliminate the inhomogeneous time-delay of speech data in the IP transmission course, the problem of non-constant caused fidelity of speech data receiving velocity and the property understood decline, and adopted the sampling rate that the voice transmit leg is handled voice digitization to notify the voice recipient, the voice transfer rate notification voice transmit leg that the voice recipient allows voice-transmission system is so that the receiving-transmitting sides co-ordination guarantees that sampling rate is consistent with regeneration rate; Adopted in the present invention speech-sound data sequence sign indicating number, speech syllable sequence code have been set, be used for the integrality that receives data is judged the recipient, when appearance transmission data are substitute, then repaired, ascending order or the additional disappearance of descending part are pressed in the reparation of sequence code; Because modern technologies studies show that, can think in the regular hour, the amplitude-frequency variation characteristic of voice signal is linear, therefore when disappearance appears in the speech-sound data sequence sign indicating number of speech data and correspondence thereof, it is the voice lines type function of variable that employing is set up with the speech-sound data sequence sign indicating number for the basis the pairing amplitude-frequency value of the speech data sign indicating number that has received, voice amplitude-frequency signal to disappearance is inserted in the pairing position of speech-sound data sequence sign indicating number as the speech data sign indicating number of repairing to voice lines type function value and after carrying out digitlization according to its corresponding speech-sound data sequence sign indicating number, to alleviate owing to part speech data sign indicating number is lost the quality of voice transmission decline that brings.
