Sound multifrequency character N；
Wherein, transmitting terminal needs judge whether the stand-by period for receiving specific dual-tone multifrequency character ' * ' is overtime, meanwhile, will
Time threshold positions the length of N number of chronomere, when over-time threshold value, then it is assumed that receive stand-by period time-out；
A3, the specific dual-tone multifrequency character ' # ' of transmission to receiving terminal, send synchronizing time point of the time point as transmitting terminal；
A4, specific dual-tone multifrequency character ' * ' is received, confirm that receiving terminal is successfully received dual-tone multifrequency character ' # '；
, wherein it is desired to judge whether the stand-by period for receiving specific dual-tone multifrequency character ' * ' is overtime；
A5, start after synchronizing time point HouNGe chronomeres to send speech frame.
A5, complete after speech frame plays, to send specific character ' # ' to receiving terminal, representing that speech frame is played and terminate, and will
Transmission time point is set to transmitting terminal synchronizing time point；
A6, specific dual-tone multifrequency character ' * ' is received, confirm that receiving terminal is successfully received dual-tone multifrequency character ' # ', represented
Wheel speech frame transmission is successfully completed, the transmission of next round speech frame can be started；
, wherein it is desired to judge whether the stand-by period for receiving specific dual-tone multifrequency character ' * ' is overtime.
As shown in figure 3, being the handling process of receiving terminal, the concrete function that receiving terminal is realized is as follows：
B1, receiving terminal receive the dual-tone multifrequency character N of numeric type, record the character, represent the N after synchronizing time point
Individual chronomere starts to receive speech frame；
B2, send specific dual-tone multifrequency character ' * ' to transmitting terminal, it is therefore an objective to notify that transmitting terminal, receiving terminal have been properly received
Dual-tone multifrequency character N；
B3, specific dual-tone multifrequency character ' # ' is received, the synchronizing time point at time point position receiver end will be received；
B4, sent to transmitting terminal and determine dual-tone multifrequency character ' * ', expression receiving terminal is successfully received character ' # '；
B5, the special dual-tone multifrequency character ' # ' of reception, terminate voice frame reception, and it is same to be set to receiving terminal at reception time point
Step time point；
B6, sent to transmitting terminal and determine dual-tone multifrequency character ' * ', expression receiving terminal is successfully received character ' # '.
Employ it is of the invention the transmitting terminal method synchronous with receiving terminal voice is realized based on dual-tone multifrequency character, solve language
Speech frame in sound quality assessment system sends the technical problem synchronous with the process of reception, in ripe dual-tone multifrequency technical field
In, communication apparatus is required to force support to directly transmit and receive " 0-9 " in call, " A-D ", 16 words of " * " and " # "
Symbol, therefore it is fairly simple in technical scheme to carry out voice frame synchronization using dual-tone multifrequency, is not restricted by external condition, improves same
Step efficiency, safe and reliable, stable performance, to the strong adaptability of test environment, with wider range of application.
In this description, the present invention is described with reference to its specific embodiment.But it is clear that can still make
Various modifications and alterations are without departing from the spirit and scope of the present invention.Therefore, specification and drawings are considered as illustrative
And it is nonrestrictive.
