Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] Such as figure 1 As shown, in this field, when a mobile terminal (such as a mobile phone) uses a radio microphone and a noise reduction microphone to make a call, the adjustment of the radio area can be realized by changing the noise reduction parameters and using different noise reduction algorithms, for example, from the radio area A is adjusted to the receiving area B. Therefore, the present invention uses this principle to adjust the sound collection area in real time by tracking the position of the caller's mouth, thereby improving the sound quality of the call.

[0029] Such as figure 2 As shown, the embodiment of the present invention relates to a method for improving the voi...

Abstract

This invention discloses a method and a device for improving conversation tone quality on mobile terminal. The method comprises steps of acquiring the location of people's mouth using the mobile terminal for conversation, acquiring a voice reception area of double microphones or multiple microphones according to the information of people's mouth, and determining whether the voice reception area exceeds a default voice reception area preset by the mobile terminal or not, if yes, adjusting the voice reception area into a voice reception area for the conversation, if not, using the default voice reception area as the voice reception area for the conversation. The invention can improve conversation tone quality on the mobile terminal through checking the people's mouth location and then adjusting the voice reception area of microphones, avoid an outgoing downlink voice area, and improve the echo elimination of hand-free calls.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and a device for improving the voice quality of a mobile terminal call. Background technique [0002] With the increasing consumption of mobile terminal products, especially the rapid development of smart phones and tablet computers, users can use terminals to communicate with others anytime, anywhere, no matter using mobile networks or WiFi (Wireless Fidelity, Wireless Fidelity) networks. At the same time, users have higher and higher requirements on the sound quality of their calls. [0003] In order to meet the needs of users for normal calls in noisy environments, dual microphones have become the standard configuration of terminal equipment. The single-mic terminal equipment adopts the steady-state noise estimation method in the noise elimination, which can only suppress the steady noise (such as wind noise), but the dual-mic terminal adopts the spatial...
