Embodiment 1

[0035] See figure 1 as shown, figure 1 Shown is a voice control method, the method comprising:

[0036] S11. Determine whether the sound pressure level of the noise at the location of the terminal is lower than a preset sound pressure level standard, or judge whether the signal-to-noise ratio of the noise at the location of the terminal is higher than the preset signal-to-noise ratio standard;

[0037] Among them, the sound pressure level refers to the loudness of the sound, and the decibel is a calculation unit to measure the loudness of the sound. The signal-to-noise ratio refers to the ratio of the normal sound signal to the noise signal when there is no signal.

[0038] S12. Adjust the frequency response of the voice according to the judgment result, so as to improve the voice.

[0039] Wherein, when the judgment result in S11 is yes, then the preset low frequency band response of the voice is raised to the preset low frequency response threshold, and / or the preset high...

Embodiment 2

[0046] See figure 2 as shown, figure 2 Shown is a terminal, including: a judging module 11 for judging whether the sound pressure level of the noise at the location of the terminal is lower than a preset sound pressure level standard, or judging whether the signal-to-noise ratio of the noise at the location of the terminal is high Based on the preset signal-to-noise ratio standard; the first equalization module 12 is used to adjust the frequency response of the speech according to the judgment result, so as to improve the speech.

[0047] Among them, the sound pressure level refers to the loudness of the sound, and the decibel is a calculation unit to measure the loudness of the sound. The signal-to-noise ratio refers to the ratio of the normal sound signal to the noise signal when there is no signal.

[0048] When the judgment result obtained by the judgment module 11 is that the sound pressure level of the noise at the location of the terminal is lower than the preset so...

Embodiment 3

[0053] See image 3 as shown, image 3 What is shown is a terminal, which includes: a judging module 21 for judging whether the sound pressure level of the noise at the location of the terminal is lower than a preset sound pressure level standard, or judging the signal-to-noise ratio of the noise at the location of the terminal Whether it is higher than the preset signal-to-noise ratio standard; the first equalization module 22 is used to adjust the frequency response of the voice according to the judgment result, so as to improve the voice.

[0054] The sound pressure level refers to the loudness of the sound, and the decibel is a calculation unit to measure the loudness of the sound. The signal-to-noise ratio refers to the ratio of the normal sound signal to the noise signal when there is no signal.

[0055] When the judgment result obtained by the judgment module 21 is that the sound pressure level of the noise at the location of the terminal is higher than the preset sou...

Abstract

The invention discloses a voice control method and a terminal. The method comprises the steps that whether the sound pressure level of the noise in the position of the terminal is lower than a preset sound pressure level standard or not is judged, or whether the signal-to-noise ratio of the noise in the position of the terminal is higher than a preset signal-to-noise ratio standard or not is judged; the frequency response of the voice is regulated according to the judgment results for improving the voice. The surrounding environment type is judged through detecting the signal-to-noise ratio or the sound pressure level of the surrounding environment of the terminal, and the frequency response of the voice is regulated according to the surrounding special environment, i.e. the conversation voice effect is improved from the down link of the voice. The scheme disclosed by the invention can be singly used and can also be combined with the scheme of using a plurality of microphones for noise reduction in the prior art, and finally, the improvement on the conversation voice effect is realized from the whole voice link.

Description

technical field [0001] The present invention relates to the technical field of voice signals, and more specifically, to a voice control method and a terminal. Background technique [0002] At present, mobile phone manufacturers generally use a dual-microphone noise reduction method to improve the voice effect of mobile phone calls. During the research and practice of the prior art, the inventors of the present invention have found that the prior art has the following problems: [0003] The entire voice link can be divided into an uplink direction and a downlink direction according to different transmission directions, that is, the direction of voice transmission through the microphone is the uplink direction, and the direction of voice reception through the handset is the downlink direction. The prior art is mainly aimed at eliminating the noise of the microphone when the external environment is very noisy, so as to improve the voice call effect. This improvement method is...
