Fig. 2 be another embodiment of the present invention provides voice modulation rate adaptation method of adjustment flow chart, please refer to
Fig. 2, the present embodiment provides a kind of machineries of consultation of preferred voice modulation rate, including following below scheme:
The supported voice modulation rate set of originating end is sent to by S201, originating end in current voice modulation rate
Responder.
In the present embodiment, in originating end, responder one as local terminal when, another opposite end each other.Preferably, audio intelligence
Energy cipher key (including wired audio intelligent cipher key and wireless audio intelligent code key) is held, mobile phone, PC in response
Deng as originating end.
If originating end and responder are to initially set up voice communication, the current voice modulation rate can be initiation
It holds, the voice modulation rate of responder initial default.The voice modulation rate of initial default can prop up for originating end, responder
Minimum voice modulation rate in the voice modulation rate set held.
If originating end and responder are used a certain voice modulation rate and carry out voice communication, the voice modulation rate
For the current voice modulation rate.
After S202, responder receive the supported voice modulation rate set of originating end, in current voice modulation speed
The supported voice modulation rate set of responder is sent to originating end in rate；Meanwhile responder is supported according to originating end
Voice modulation rate set and the supported voice modulation rate set of responder calculate the voice modulation rate set that both sides support;
Optimal voice modulation is chosen from the voice modulation rate set that both sides support according to the consensus selection rule of both sides
Rate;Selected optimal voice modulation rate is not necessarily highest voice modulation rate, depending on the consensus choosing of both sides
Depending on taking rule.
The selection rule that the negotiation step of selection rule can occur to negotiate before step S201 includes but does not limit to
In act set forth below, can only can guarantee selected by both sides it is identical voice modulation rate: be supported from both sides
Voice modulation rate set in, choose highest voice modulation rate as optimal voice modulation rate;Or it is equal from both sides
In the voice modulation rate set of support, the second high voice modulation rate is chosen as optimal voice modulation rate;Or from
In the voice modulation rate set that both sides support, the high voice modulation rate of third is chosen as optimal voice modulation rate etc.
Deng.
S203, originating end receive the supported voice modulation rate set of responder that responder is sent；Originating end is according to hair
The supported voice modulation rate set of origin or beginning and the supported voice modulation rate set of responder calculate the sound that both sides support
Frequency modulation rate set;According to the consensus selection rule of both sides, from the voice modulation rate set that both sides support, choose most

1kS/s, 4kS/s, 6kS/s, 8kS/s, 10kS/s, 12kS/s, 14kS/s, 20kS/s, and enable bit value be 0 indicate
Originating end does not support that voice modulation rate corresponding with the bit, the value of bit are that 1 expression originating end is supported and the bit
The corresponding voice modulation rate in position, then binary bit sequence 00000011 indicate originating end only support 1kS/s, 4kS/s this
Two kinds of voice modulation rates.
Preferably, the supported voice modulation rate set of originating end and the supported voice modulation rate set of responder are indicated
The two binary bit sequences in, bit is consistent with the corresponding relationship of voice modulation rate, in this case, originating end and
Responder can carry out distance (XOR) operation to this two binary bit sequences step-by-step, obtain the audio tune that both sides support
Rate set processed.Preferably, binary bits sequence can be arranged according to the sequence of voice modulation rate from high to low or from low to high
Bit in column.If successively indicating voice modulation rate from low to high from low level to high-order in binary bit sequence,
Voice modulation rate corresponding to the highest-order bit in exclusive or result sequence can be chosen as optimal voice modulation rate；
If successively indicating voice modulation rate from high to low from low level to high-order in binary bit sequence, exclusive or knot can be chosen
Voice modulation rate corresponding to lowest bit position in infructescence column is as optimal voice modulation rate.
The present embodiment sends itself supported voice modulation rate set by mutual opposite other side, and unified selection both sides are equal
Mode of the highest voice modulation rate as optimal voice modulation rate in the voice modulation rate set of support, to negotiate most
Good voice modulation rate not only realizes the adaptive adjustment to voice modulation rate, and simple and practical.
