Technical Field
The utility model relates to the field of communication technology, concretely relates to speech coding device.
Background
With the development of voice communication technology, compressing the transmission bandwidth of voice signals and reducing the transmission rate of channels are always the goals pursued, and voice coding plays an important role in achieving the goals. In the voice communication process, the voice quality is improved by adopting a high-speed coding mode, but more system resources are required; the quality of speech is degraded by using a low-rate coding scheme. The voice coding device in the prior art can not select a proper voice coding rate in a call system, thereby reducing the voice quality in the call process and being incapable of reasonably and effectively utilizing system resources. Therefore, it is necessary to provide a speech encoding apparatus capable of selecting an appropriate speech encoding rate.
Disclosure of Invention
An object of the utility model is to provide a speech coding device solves the speech coding device among the prior art and can't be according to selecting suitable speech coding rate in the speech system to the speech quality of conversation in-process and the problem that can not reasonable effectual utilization system resource have been reduced.
In order to solve the technical problem, the utility model adopts the following technical scheme: a speech coding device comprises a sound sensor 1 for collecting sound signals, a sound increase judger 2 for judging whether the volume of a speaker is increased or not, a network bandwidth collecting device 3, a controller 4 and a speech coding device 5, wherein the sound sensor 1 is in signal connection with the sound increase judger 2, the sound increase judger 2 is in signal connection with the input signal of the controller 4, the network bandwidth collecting device 3 is in signal connection with the input signal of the controller 4, and the output signal of the controller 4 is in signal connection with the speech coding device 5.
The sound improvement judger 2 comprises a filter 6, an amplifier 7 and a comparator 8, wherein the sound sensor 1 is in signal connection with the filter 6, the filter 6 is in signal connection with the amplifier 7, the amplifier 7 is in signal connection with the comparator 8, and an output signal of the comparator 8 is connected with an input of the controller 4.
Compared with the prior art, the beneficial effects of the utility model are that: the application provides a voice coding device, which collects voice information of a user through a sound sensor and transmits the voice information to a sound improvement judger, the sound improvement judger judges whether the volume of the user is improved, if the volume of the user is improved, the coding rate of the coding device is accelerated, and if the volume of the user is not improved, the coding rate of the coding device is not changed; and then the network bandwidth acquisition device acquires network information, and if the network is congested, the coding rate of the coding device is reduced, so that the voice coding rate is selected according to actual needs, and the waste of system resources and the reduction of voice call quality are avoided.

In the figure: the voice recognition method comprises the steps of 1-a voice sensor, 2-a voice improvement judger, 3-a network bandwidth acquisition device, 4-a controller, 5-a voice coding device, 6-a filter, 7-an amplifier and 8-a comparator.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1 to 3, a speech coding apparatus comprises a sound sensor 1 for collecting a sound signal, a sound increase determiner 2 for determining whether the speaker volume is increased, a network bandwidth collecting device 3, a controller 4, and a speech coding apparatus 5, wherein the sound sensor 1 is in signal connection with the sound increase determiner 2, the sound increase determiner 2 is in signal connection with an input of the controller 4, the network bandwidth collecting device 3 is in signal connection with an input of the controller 4, and an output of the controller 4 is in signal connection with the speech coding apparatus 5.
The sound-up determiner 2 increases the sound volume consciously by making use of the fact that a person is not clearly heard when talking on a voice. The voice sensor 1 collects voice by a user and transmits the voice to the voice increasing judger 2, a reference value of voice stability is arranged in the voice increasing judger 2, whether the volume of a speaker is increased or not is judged by the voice increasing judger 2, if the volume of the speaker is increased, the controller 4 controls the coding rate of the voice coding device 5 to be increased, and if the volume is not increased, the coding rate of the voice coding device 5 is not increased. The network bandwidth acquisition device 3 is a controller 4 on the network side and is used for acquiring network bandwidth and transmitting network information to the controller 4, the controller 4 stores a threshold value of the network information, and when the network is congested, the controller 4 controls the encoding rate of the voice encoding device 5 to be reduced.
The sound improvement judger 2 comprises a filter 6, an amplifier 7 and a comparator 8, the sound sensor 1 is in signal connection with the filter 6, the filter 6 is in signal connection with the amplifier 7, the amplifier 7 is in signal connection with the comparator 8, and an output signal of the comparator 8 is connected with an input of the controller 4. When the sound sensor is used, the sound sensor 1 transmits a detected sound signal to the filter 6, the filter 6 performs filtering processing on the interference sound, amplifies the sound signal after the filtering processing, and finally transmits the sound signal to the comparator 8 to be compared with a preset reference value.
The working principle is as follows: when the voice coder is in use, the voice sensor 1 continuously collects voice of a user, transmits the voice to the voice increasing judger 2, judges whether the volume of a speaker is increased or not through the voice increasing judger 2, if the volume of the speaker is increased, the controller 4 controls the coding rate of the voice coding device 5 to be increased, and if the volume is not increased, the coding rate of the voice coding device 5 is not increased. The network bandwidth acquisition device 3 is a controller 4 on the network side and is used for acquiring network bandwidth and transmitting network information to the controller 4, the controller 4 stores a threshold value of the network information, and when the network is congested, the controller 4 controls the encoding rate of the voice encoding device 5 to be reduced.
