Fig. 1 shows a flowchart of a voice long-time continuous packet loss compensation method in this embodiment. The voice long-time continuous packet loss compensation method can be applied to a telephone communication system, and can be realized by adopting the telephone communication system when voice communication is carried out. The telephone communication system can be applied to computer equipment, wherein the computer equipment can perform human-computer interaction with a user, and the computer equipment comprises, but is not limited to, computers, smart phones, tablets and other equipment. As shown in fig. 1, the method for compensating for long-time continuous packet loss of voice includes the following steps:
s10: an initial voice packet in a voice call is determined.
The initial voice packet refers to an initial position of a voice frame for call setup, and is used for determining the start of a section of call. It can be understood that the voice packet and the voice frame in this embodiment are the same concept, and the voice of each frame is used as the minimum unit in the call, corresponding to each voice packet.
In one embodiment, to determine the timing for buffering the voice packets, an initial voice packet in the voice call may be determined, from which it may be determined that the user is in the call, and the buffering of the voice packets may be started.
S20: and inputting the voice packets in the voice call into a buffer according to the initial voice packet in sequence, wherein the voice packets with a preset number are used as a group of word frame groups, and each group of word frame groups corresponds to a number in sequence.
The buffer is a buffer for storing voice packets, and can be used as a data source for packet loss compensation when voice packets are continuously lost for a long time.
The word frame group is obtained by sequentially combining a preset number of voice packets, where the preset number may be specifically 18. It can be understood that the number of words (hereinafter, the Chinese character is taken as an example) that a person can speak per minute is generally between 160 and 180, which is equivalent to speaking 2.66-3 words per second. The call in mobile communication is transmitted with one voice frame/voice packet every 20ms as frequency, and the total number of the voice packets is 50 in one second, which is equivalent to 16.6-18.7 voice packets corresponding to each Chinese character. The preset number of voice packets is used as a word frame group, and the relevance between the voice packets and the words can be embodied according to the word frame group. A word frame group may essentially represent a word, subject to the initial speech packet determination. The word frame group is used as a compensation unit for compensating the continuously lost voice packets, a foundation is provided for subsequent packet loss compensation, the lost voice packets can be output by using the words as units after compensation, and a user can still listen to the voice under the condition of not sending the voice packets for a long time.
In one embodiment, in the case of determining the initial voice packet, the voice packets in the voice call may be sequentially input into the buffer in a word-frame association (word-frame group). Each group of the word frame groups corresponds to a number in sequence, and the accuracy of the voice packet in the input buffer on the time sequence can be ensured.
Specifically, as shown in fig. 2, fig. 2 shows a caching process based on word frame group association:
according to the relevance of the words embodied by the word frame group, "i", "and" two words in fig. 2 correspond to M (a preset number) voice packets, respectively. "I" is the first word, and the number of M voice packets to which the word belongs is 1; "and" is the second word, and the number of M voice packets to which it belongs is 2; and then classifying the voice packets according to the classification until the voice packets within T seconds are all buffered in a buffer.
Further, in step S20, according to the initial voice packet, sequentially inputting the voice packets in the voice call into the buffer, specifically including:
s211: and judging whether the current voice packet is an initial voice packet or not, or whether the initial voice packet exists or not, and if the current voice packet is the initial voice packet or the initial voice packet exists, inputting the voice packets in the voice call into the buffer in sequence.
It can be understood that, in each buffering process, since the buffering of the next voice packet is not performed from the initial voice packet in each buffering process, it is necessary to determine whether the current voice packet is the initial voice packet or whether the initial voice packet already exists. It will be appreciated that when the initial voice packet is determined, the voice packets in the voice call are input into the buffer in order, assuming that the call has already started. The caching process in the implementation can ensure the accuracy of the voice packet on the time sequence, and the cached voice packet is used as a data source for packet loss compensation.
S212: after the voice packets in the voice call are sequentially input into the buffer each time, detecting the storage space condition of the buffer, if the available storage space exists in the buffer, acquiring the next voice packet, continuously judging whether the current voice packet is the initial voice packet or not or whether the initial voice packet exists or not, and if so, sequentially inputting the voice packets in the voice call into the buffer.
S213: and if the buffer has no available storage space, stopping inputting the voice packet into the buffer.
It is understood that if the buffer has available memory space, the step S211 is continued until the buffer has no available memory space, and the voice packet input into the buffer is stopped.
In steps S211-S213, a specific embodiment is provided for sequentially inputting the voice packets in the voice call into the buffer according to the initial voice packet, and the mode for entering the buffer can be determined according to the initial voice packet, and the voice packets in the voice call are sequentially input into the buffer as the data source for compensating the packet loss of the call.
Further, before step S20, that is, before the voice packets in the voice call are sequentially input into the buffer according to the initial voice packet, the method further includes:
s221: and initializing the counting value of the voice packet.
The count value of the voice packet may be initialized to 0. It is understood that, before buffering, to ensure the accuracy of the timing sequence of the voice packets input into the buffer and to establish different groups of word frame groups, the count value of the voice packets may be initialized.
S222: the number is initialized.
Wherein the initialization value of the number may be 1.
It is to be understood that, in steps S221-S222, the counting value of the voice packets may be obtained as word frame groups in time sequence, and the number of the word frame groups may be distinguished from the word frame groups in time sequence. The counting value and the number of the voice packet are initialized, so that the accurate acquisition of the word frame group can be realized.
Further, in step S20, the step of inputting the voice packets in the voice call into the buffer in sequence includes:
s231: when the voice packets in the voice call are input into the buffer in sequence each time, whether the number of the input voice packets reaches a preset number is judged.
S232: if not, storing the input voice packet into the cache with the same number as the last input voice packet, and increasing the counting value of the input voice packet by 1.
S233: if the number reaches the preset value, the counting value of the input voice packet is reset to 1, the number is increased by 1 to obtain a new number, and the input voice packet is stored from the storage position of the new number in the buffer.
In steps S231-S233, a change rule of a count value of the voice packet, a storage location of the voice packet, a change rule of a number, and the like are described each time the voice packet in the voice call is sequentially input into the buffer, and a frame group of words can be obtained in time sequence in the buffering process to highlight a correlation between the voice packet and the word, so as to provide a technical realization premise for a subsequent compensation of a long-time continuous packet loss, so that a user can listen to the voice as usual after the voice compensation.
S30: and detecting the voice packets continuously lost in the voice call, and determining the number and the storage position of the continuously lost voice packets.
S40: and when the number of the voice packets which are continuously lost is larger than or equal to the preset number, acquiring the word frame groups in the buffer according to the numbering sequence, and sequentially compensating to the storage positions of the voice packets which are continuously lost according to the word frame groups.
It can be understood that, when the number of the voice packets lost continuously is greater than or equal to the preset number, the buffer has at least one word frame group, and at this time, the word frame groups are sequentially compensated to the storage positions of the voice packets lost continuously, so that the lost voice packets can be supplemented in units of words, and when a voice call has a long-time continuous packet loss, the user can hear the voice.
Further, in step S40, sequentially compensating to the storage location of the consecutive lost voice packets according to the word frame group, specifically including:
s411: and if the result of dividing the number of the continuously lost voice packets by the preset number is a positive integer, sequentially compensating the voice packets in the word frame group to the storage position of the continuously lost voice packets according to the sequence of the numbers of the word frame group.
It can be understood that, when the result of dividing the number of consecutive lost voice packets by the preset number is a positive integer, it means that the lost voice packets can be just compensated by using the positive integer number of word frame groups, and there is no lost voice packet that is not compensated, so that the integrity of compensation can be ensured.
S412: and if the number of the continuously lost voice packets is greater than the preset number and the result of dividing the number of the continuously lost voice packets by the preset number has a remainder, sequentially compensating the voice packets in the target word frame group to a first storage position of the continuously lost voice packets according to the sequence of the numbers, wherein the target word frame group is a word frame group which is corresponding to the quotient value obtained by dividing the number of the continuously lost voice packets by the preset number and is sorted according to the numbers.
S413: and acquiring voice packets with the number of the previous remainders in sequence from the word frame group corresponding to the number to be accessed by adopting a remainder packet processing mode, wherein the number of the remainders is the number corresponding to the number of the remainders.
It can be understood that, when the number of the consecutive lost voice packets is greater than the preset number and a remainder exists as a result of dividing the number of the consecutive lost voice packets by the preset number, the manner of processing the remaining packets refers to sequentially obtaining the voice packets with the number of the previous remainders in the word frame group corresponding to the number to be accessed after sequentially compensating the voice packets in the target word frame group to the first storage location of the consecutive lost voice packets.
S414: and compensating the voice packets with the previous and remaining numbers to a second storage position of the continuously lost voice packets in sequence by adopting a packet compensation mode, wherein the storage position of the continuously lost voice packets comprises a first storage position and a second storage position.
In steps S412-S413, considering the completeness of compensation, when there is no multiple relation between the continuously lost voice packets and the word frame groups, as shown in fig. 3, in the Y target word frame groups, the word frames included in each group respectively compensate M lost voice packets, the uncompensated part (called as a collision part) of the Y target word frame groups can be sequentially obtained by using the number-to-be-accessed word frame group (here, the next group of word frame groups after the last group of target word frame groups is numbered as Y +1) to obtain the number of the preceding remainder (H) voice packets, the number of the preceding remainder voice packets is used to sequentially compensate the remaining uncompensated and continuously lost voice packets, therefore, the compensation integrity when the multiple relation does not exist between the voice packets which are continuously lost and the word frame group is realized, and the user can listen to the complete voice as much as possible.
In steps S411-S414, a specific embodiment is provided for sequentially compensating to the storage locations of consecutive lost voice packets according to the word frame groups, and when there is a multiple relationship between consecutive lost voice packets and the word frame groups, or there is no multiple relationship, the word frame groups are taken as the units of compensation, so as to ensure the integrity of compensation.
Further, the method for compensating for long-time continuous packet loss of voice further comprises:
s421: and when the number of the voice packets which are continuously lost is smaller than the preset number, acquiring the target voice packets in the buffer in a residual packet processing mode, wherein when the number of the voice packets which are continuously lost is smaller than the preset number, the residual packet processing mode is to acquire the voice packets of the previous target number in sequence from the word frame group corresponding to the number to be accessed, and the target number is the number of the voice packets which are continuously lost.
S422: and compensating the target voice packet to the storage position of the continuously lost voice packet in sequence by adopting a residual packet compensation mode.
In steps S421 to S422, for the case that the number of consecutive lost voice packets is less than the preset number, the compensation can be performed by using a complementary packet compensation method, and the characteristics of the word frame group can also be embodied, for example, if there are 15 consecutive lost voice packets, then the compensation is performed on the first 15 voice packets of the word frame group in number 1, and then there is a possibility that the first 15 voice packets of the word frame group include the associated information corresponding to the word. Therefore, with the target number of voice packets before the word frame group, an effective voice compensation effect can be achieved as well.
In an embodiment, the voice packet loss compensation method for a long time continuous period may be divided into two stages, one is a buffering stage and the other is a compensation stage.
Specifically, fig. 4 shows a flow chart of the caching phase in an embodiment of the invention. As can be seen in fig. 4:
in step S501, initialization is performed on the serial number and the value of the preset number (M).
In step S502, determining whether the current voice packet is an initial voice packet or has an initial voice packet, if yes, executing step S503; otherwise, step S507 is executed.
In step S503, the current voice packet is marked as a valid packet, and then step S504 is executed.
In step S504, it is determined whether the number of consecutively received voice packets satisfies M, and if not, step S505 is executed; otherwise, step S509 is performed.
In step S505, the current voice packet is sequentially buffered in a buffer with the same number as the last voice packet.
In step S506, the M count value is incremented by 1, and then step S512 is performed.
In step S507, the current voice packet is marked as an invalid packet, and step S508 is executed.
In step S508, the invalid voice packet is filtered out, the next voice packet is extracted, and the process returns to step S502.
In step S509, the number is increased by 1.
In step S510, the voice packets are buffered in the buffer from the position of the new number in sequence.
In step S511, the value of M is initialized and reset to 1.
In step S512, determining whether the buffer is full, if not, extracting the next voice packet, and returning to step S502; otherwise, the caching process is ended.
Specifically, FIG. 5 shows a flow chart of the compensation phase in one embodiment of the present invention. As can be seen in fig. 5:
in step S601, the current voice packet is analyzed, and step S602 is executed after packet loss is detected.
In step S602, the number N of consecutive lost packets is calculated, and step S603 is executed.
In step S603, the size relationship between N and M (a preset number) is determined, and if the number of consecutive packet losses N is less than M, step S606 is executed. Otherwise, step S604 is executed.
In step S604, packet loss is compensated in units of word frame groups and in the order of numbers, and step S605 is performed.
In step S605, after packet loss is continuously compensated, it is determined whether the number of remaining uncompensated packet losses is less than M, and if so, step S606 is executed. Otherwise, step S607 is executed.
In step S606, the first H voice packets in the next number in the buffer are searched, and then step S608 is executed.
In step S607, packet loss is compensated in units of word frame groups and in the order of numbering, and then the packet loss compensation process is ended.
In step S608, the remaining packet compensation is performed, and then the packet loss compensation process is ended.
In the embodiment of the invention, a buffer is adopted to buffer the voice packets in the voice call, and the word frame groups obtained in sequence are adopted as the compensation units for compensating the continuously lost voice packets in the voice call in the buffer. The incidence relation of the number of the word frame groups obtained in sequence and the words spoken by the user can output the lost voice packet by taking the words as a unit after compensation under the condition of ensuring correct time sequence, so that the user can still listen to the voice under the condition of not sending the voice packet for a long time.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
