A kind of volume automatic regulating method comprises step: by input unit typing external voice; Described external voice is converted to digital signal; The discriminating digit signal is that environmental noise still is user's voice; If environmental noise, the intensity of judgement environmental noise; Obtain the volume adjusting corresponding from the table of comparisons of a noise intensity and volume adjusting with environmental noise intensity; Wherein said table of comparisons definition is heightened the volume of the partner that receives along with the increase of environmental noise intensity; Regulate according to the volume obtained the volume of the partner that receives is regulated and exported.
Use apparatus for automatically regulating sound volume of the present invention and method, according to the noise level of user's surrounding environment and the volume of regulating voice outputs such as loud speaker or earphone automatically, therefore, the user is when listening to the partner audio frequency, needn't the manual adjustments volume, convenient, comfortable, avoided simultaneously regulating volume and the problem of hearing damage because forget.
Description of drawings
Fig. 1 is the hardware structure diagram of the apparatus for automatically regulating sound volume of the embodiment of the invention.
Fig. 2 is the flow chart of the self-regulating method of volume of the embodiment of the invention.
Embodiment
Below in conjunction with accompanying drawing, the technical scheme in the embodiment of the invention is described in detail.
With reference to shown in Figure 1, it is the hardware structure diagram of the apparatus for automatically regulating sound volume 10 in the execution mode.Described apparatus for automatically regulating sound volume 10 is applied to mobile phone, landline telephone, computer etc., and some can be realized in the electronic equipment of both sides' voice communication, regulate the size of the other side's voice of electronic equipment output in both sides' communication process automatically according to environmental noise.Apparatus for automatically regulating sound volume 10 is made up of following each several part in this embodiment: memory cell 150, input unit 120, analog/digital conversion unit 130, processing unit 100.
Analog/digital conversion unit 130 is used for the sound of input unit 120 typings is converted into digital signal and exports to processing unit.
Processing unit comprises a voice recognition module 104 and a volume adjusting module 106.
The digital signal that voice recognition module 104 is used to discern 130 outputs from the analog/digital conversion unit is user's voice or environmental noise, particularly, described voice recognition module 104 judges that according to the audio document of the specific user of storage in the memory cell 150 digital signal of 130 outputs from the analog/digital conversion unit is user's voice or environmental noise.If environmental noise offers volume adjusting module 106 with environmental noise; If user's voice will be transferred to partner after user's speech coding.In other real-time modes, equally also give partner with the environmental noise coding transmission.
Sound volume regulation unit 160 is used for the control according to above-mentioned volume adjusting module 106, the audio frequency size of the partner that receives is regulated, and wait voice output to export by loud speaker 170 or earphone (figure does not show).
When using above-mentioned volume automatic regulating device 10, volume automatic regulating device 10 can be according to the noise level of user's surrounding environment and the size of regulating the other side's voice that receive automatically, therefore, the user is when receiving calls, needn't the manual adjustments volume, convenient, comfortable, avoided simultaneously regulating volume and the problem of hearing damage because forget.
See also the flow chart of Fig. 2, comprise the steps: for the self-regulating method of volume of the embodiment of the invention
Step S301 opens the automatic volume regulatory function, by input unit typing external voice;
Step S302 is converted to digital signal with this sound;
Step S303, discriminating digit signal are that environmental noise still is user's voice; If environmental noise enters step S304,, particularly, be that environmental noise still is user's voice according to specific user's the audio document discriminating digit signal of storage if user's voice enter step S305;
Step S304 will be transferred to partner after user's speech coding, and flow process finishes;
Step S305 is identified as the digital signal of environmental noise every predetermined time interval sampling, judges the intensity of environmental noise, particularly, judges the noise intensity interval that environmental noise falls into;
Step S306, the table of comparisons of regulating from a noise intensity and volume obtains and the corresponding volume of this noise intensity is regulated, and particularly, obtains and the interval corresponding volume value of this noise intensity or volume-leveling value or adjusting ratio; In the present embodiment, interval corresponding volume value of noise intensity that noise intensity is higher or volume-leveling value or volume adjusting ratio are greater than interval corresponding volume value of the lower noise intensity of noise intensity or volume-leveling value or volume and regulate ratio.
Step S307 according to above-mentioned volume value or volume-leveling value or adjusting ratio, regulates and exports the audio frequency size of the partner that receives, and flow process finishes.
In another embodiment, equally also give partner with the environmental noise coding transmission.
Use above-mentioned volume automatic regulating method, according to the noise level of user's surrounding environment and the size of regulating the other side's voice that receive automatically, therefore, the user is when receiving calls, needn't the manual adjustments volume, convenient, comfortable, avoided simultaneously regulating volume and the problem of hearing damage because forget.
Those skilled in the art will be appreciated that; above execution mode only is to be used for illustrating the present invention; and be not to be used as limitation of the invention; as long as within connotation scope of the present invention, appropriate change and the variation that above embodiment did all dropped within the scope of protection of present invention.
