[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments. Any technology implemented based on the content of the present invention belongs to the scope of the present invention.

[0032] Before the voice automatic selection and switching control method of the present invention works, it is necessary to pre-configure a voice optimization strategy. As Figure 1 shown, by verifying the user's login account, it is determined whether the user has the operation authority. If the user has the operation authority, the user logs in to the voice optimization strategy configuration interface, and then configures the voice optimization strategies of each voice terminal corresponding to different targets by operating in the voice optimization strategy configuration interface. The specific configuration operations include: configuring the voice terminal operation parameter strategy, configuring the voice terminal preference order, and configuring the channel sound source type of the voice terminal.

[0033] Among them, the configuration of the voice terminal operation parameter strategy includes: configuring the preset thresholds corresponding to the packet frequency reference value, packet loss rate, and out-of-order rate. The configuration of the voice terminal preference order includes: sorting various voice terminals of the target, and when the voice terminal operation parameter strategy cannot optimize the sound source, the sound source is optimized through the voice terminal preference order. The configuration of the channel sound source type of the voice terminal is to distinguish whether the sound source transmitted by each channel is a low-speed sound source or a high-speed sound source.

[0034] After the configuration is completed, the configuration data is sent to the web background for data processing and written into the database; then the policy information is displayed through the voice preference policy configuration interface.

[0035] In addition, before the voice automatic selection and switching control method of the present invention works, the high-fidelity dispatching system also needs to be configured, such as Figure 2 shown, by verifying the user's login account, it is determined whether the user has the operation authority. If the user has the operation authority, then log in to the high-fidelity dispatching system configuration interface, and then through operations on the high-fidelity dispatching system configuration interface, configure the mapping relationship between each voice terminal user corresponding to different targets and the voice channel, and the classification of dispatching users (including ordinary dispatching users, audio network users, and voice terminal users). In addition, the high-fidelity dispatching system can also monitor the user status such as the online status, shielding status, and separation status of dispatching users, and display the voice terminal channel and the name of the sound reinforcement system corresponding to the voice terminal user.

[0036] After the configuration is completed, the configuration data is sent to the web background for data processing and written into the database; then the configuration information is displayed through the high-fidelity dispatching system configuration interface.

[0037] Before the voice automatic selection and switching control method of the present invention works, the sound source output sound reinforcement system also needs to be configured, such as Figure 3 shown, by verifying the user's login account, it is determined whether the user has the operation authority. If the user has the operation authority, then log in to the sound source and sound reinforcement system planning interface, and then through operations on the sound source and sound reinforcement system planning interface, configure the relationship between different target voices and the sound reinforcement system users, that is, the mapping relationship between the voice of the specified target and the audio network user during the specified task period planned.

[0038] After the configuration is completed, the configuration data is sent to the web background for data processing and written into the database; then the configuration information is displayed through the sound source and sound reinforcement system planning interface.

[0039] After the above configuration work is completed, the voice reception and preprocessing work starts. First, load the voice terminal of the target and the sound source configuration of the voice terminal channel. Then, from the terminal data reported by the receiving monitoring system in real time, find the real-time operation data of the target forwarding server, and obtain the data source information of the voice terminal in real time. At the same time, from the terminal data reported by the receiving monitoring system in real time, find the real-time operation data of the corresponding voice terminal, and match the destination IP and destination port of the downstream channel according to the local IP address of the terminal and the destination port (receiving) to find the corresponding channel. By analyzing the power-on state of the voice terminal, the packet frequency, the local synchronization state of the channel, the codec module state, and the local synchronization state and local frame synchronization state of the corresponding downstream channel, determine whether it is powered on. If it is powered on, start to execute the steps of the voice automatic selection and switching control method of the present invention.

[0040] As Figure 4 shown, for the low-speed voice selection and switching control process, it includes:

[0041] Collect the operation state parameters of each voice terminal corresponding to the specified target in real time (such as packet frequency, local synchronization state, packet loss, out-of-order, codec module state, etc.);

[0042] According to the operation state parameters of the voice terminal, judge whether the packet frequency is greater than zero, and whether the local synchronization state of the channel, the codec state, the local synchronization state of the downstream channel, and the local frame synchronization state are all normal. If the packet frequency is greater than zero and the local synchronization state of the channel, the codec state, the local synchronization state of the downstream channel, and the local frame synchronization state are all normal, then determine that the voice channel has voice.

[0043] Then, according to the pre-configured voice optimization strategy, select the sound source from the voice channels with voice. Specifically, determine the voice quality level of the voice channel according to the average packet frequency of the voice within the selected time period, and use the sound source with the best voice quality level as the selected sound source. Among them, if the average packet frequency of the voice within the selected time period deviates less from the preset packet frequency reference value, the voice quality is better. In implementation, multiple ranges can be set according to the size of the deviation of the average packet frequency from the preset packet frequency reference value, and each range corresponds to a corresponding voice quality level.

[0044] If the determined voice quality levels of all voice channels are the same, according to the preset priority order of each voice channel, use the sound source in the voice channel with the highest priority as the selected sound source.

[0045] After selecting the sound source, according to the mapping relationship between the voice terminal users of the specified target and the voice channels pre-configured, unshield the voice terminal users corresponding to the selected sound source and shield other voice terminal users of the specified target; and, according to the mapping relationship between the voice of the specified target and the audio network users during the pre-planned specified task period, control the corresponding audio network users to be separated or unseparated, so that different target sound sources are output to the specified sound reinforcement system.

[0046] As Figure 5 shown, for the high-speed voice selection and switching control process, it includes:

[0047] Real-time collect the operating state parameters of each voice terminal corresponding to the specified target (such as packet frequency, local synchronization status, packet loss, out-of-order, codec module status, etc.);

[0048] According to the operating state parameters of the voice terminal, judge whether the packet frequency is greater than zero, and whether the channel local synchronization status, codec status, downlink channel local synchronization status, and local frame synchronization status are all normal. If the packet frequency is greater than zero and the channel local synchronization status, codec status, downlink channel local synchronization status, and local frame synchronization status are all normal, then determine that the voice channel has voice.

[0049] Then, according to the pre-configured voice optimization strategy, select a sound source from the voice channels with voice; specifically, according to the average packet frequency, packet loss rate, and out-of-order rate of the voice within the selected time period, determine the voice quality level of the voice channel, and use the sound source with the best voice quality level as the selected sound source. Among them, if the average packet frequency of the voice within the selected time period deviates less from the preset packet frequency reference value, the voice quality is better; if the packet loss rate and out-of-order rate of the voice within the selected time period are smaller, the voice quality is better. If the packet loss rate or out-of-order rate exceeds the corresponding preset threshold, then abandon the corresponding voice channel.

[0050] During implementation, by calculating the increment of the number of lost packets (i.e., the packet loss rate) within a specified time period and comparing it with the set threshold, the smaller the packet loss rate, the better the voice quality. When the packet loss rate is less than the threshold, set the voice quality level according to the ratio of the packet loss rate to the threshold; when the packet loss rate exceeds the threshold, it is considered that the voice quality of this channel is very poor, and the voice output from this channel is abandoned.

[0051] The formula for calculating the packet loss rate: lostRate = ΔlostCount / Δt, where Δt is the time difference and ΔlostCount is the increment of the number of lost packets within the time period of Δt.

[0052] Quality level: LQlevel = Math.floor((lostRate) / lostThreshold / n)), where Math.floor() represents the floor function, n represents the number of segments into which the threshold is divided, which is the number of levels of the quality level, and n is configurable. When lostRate > lostThreshold, LQlevel is set to -1, indicating that the voice quality of this channel is very poor and it is abandoned for use.

[0053] Moreover, by calculating the increment of the out-of-order number (i.e., the out-of-order rate) within a specified time period and comparing it with the set threshold, the smaller the out-of-order rate, the better the voice quality. When the out-of-order rate is less than the threshold, the voice quality level is set according to the ratio of the out-of-order rate to the threshold; when the out-of-order rate exceeds the threshold, it is considered that the voice quality of this channel is very poor and the voice output by this channel is abandoned.

[0054] Formula for calculating the out-of-order rate: disorderRate = ΔdisorderCount / Δt, where Δt is the time difference and ΔdisorderCount is the increment of the out-of-order number within the time period of Δt.

[0055] Quality level: DQlevel = Math.floor((disorderRate) / (disorderThreshold / n)), where Math.floor() represents the floor function, n represents the number of segments into which the threshold is divided, which is the number of levels of the quality level, and n is configurable. When disorderRate > disorderThreshold, DQlevel is set to -1, indicating that the voice quality of this channel is very poor and it is abandoned for use.

[0056] In the specific implementation of the present invention, different weight coefficients are assigned to the quality levels corresponding to the average packet frequency, packet loss rate, and out-of-order rate respectively, and then the sum is calculated. According to the magnitude of the obtained sum, the voice quality level of the voice channel that comprehensively combines the three evaluation indicators of the average packet frequency, packet loss rate, and out-of-order rate of the voice is determined.

[0057] If the determined voice quality levels of all voice channels are the same, according to the preset priority order of each voice channel, the sound source in the voice channel with the highest priority is used as the selected sound source.

[0058] After the selected sound source is determined, according to the mapping relationship between the voice terminal users of the specified target and the voice channels configured in advance, the shielding of the voice terminal users corresponding to the selected sound source is cancelled and the other voice terminal users of the specified target are shielded; and, according to the mapping relationship between the voice of the specified target and the audio network users during the pre-planned specified task period, the corresponding audio network users are controlled to be separated or the separation is cancelled, so that different target sound sources are output to the specified sound reinforcement system.

[0064] In the voice automatic selection and switching control system of the present invention, the voice detection module is configured to judge whether the packet frequency is greater than zero according to the operating state parameters of the voice terminal, and whether the channel local synchronization state, the codec state, the downlink channel local synchronization state, and the local frame synchronization state are all normal. If the packet frequency is greater than zero and the channel local synchronization state, the codec state, the downlink channel local synchronization state, and the local frame synchronization state are all normal, it is determined that the voice channel has voice.

[0065] In the voice automatic selection and switching control system of the present invention, the voice optimization module is configured to determine the voice quality level of the voice channel according to the average packet frequency, packet loss rate, and out-of-order rate of the voice within the selected time period, and use the sound source with the optimal voice quality level as the selected sound source; wherein, if the average packet frequency of the voice within the selected time period deviates less from the preset packet frequency reference value, the voice quality is better; if the packet loss rate and out-of-order rate of the voice within the selected time period are smaller, the voice quality is better. If the packet loss rate or out-of-order rate exceeds the corresponding preset threshold, the corresponding voice channel is abandoned.
