Embodiment Construction

[0058] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0059] The present invention provides a method for noise reduction in conversation of an intelligent terminal.

[0060] see figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the noise reduction method for the smart terminal of the present invention.

[0061] In the first embodiment, the method for noise reduction in smart terminal calls includes:

[0062] Step S101, when the voice communication starts, the first terminal collects the call voice and environmental noise;

[0063]Example 1. The microphone in the first terminal is used as the main microphone. During the call, the first terminal collects the call voice and environmental noise. Preferably, when the user of the first terminal is talking, the call voice signal and the noise are collected by the main microphone. Environmental noise...

Abstract

The invention discloses an intelligent terminal call noise reduction method comprising the following steps: a first terminal acquires call speech and ambient noise at the start of speech call; the first terminal judges whether the first terminal is in a quiet state according to the acquired call speech and/or ambient noise; noise reduction is performed on the call speech according to ambient noise sent by a second terminal if the first terminal is not in a quiet state; and noise reduction is not performed if the first terminal is in a quiet state. The invention further discloses an intelligent terminal. The problem that call is susceptible to interference of ambient noise as an intelligent terminal, especially a wearable intelligent terminal, is compact in structure and cannot be equipped with a plurality of microphones to perform de-noising is effectively solved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a noise reduction method for an intelligent terminal and the intelligent terminal. Background technique [0002] Smart terminals, especially wearable smart terminals (for example, smart watches, smart glasses, etc.), as a new type of smart terminal, can be conveniently worn on specific body parts of people. Existing wearable smart terminals generally have wireless call functions, which are usually used in special environments, for example, when people's hands cannot hold or operate mobile terminals (such as mobile phones, tablet computers, etc.), through Using this type of wearable smart terminal to communicate directly with other terminal devices greatly expands the scenarios of people's voice calls. However, limited by the relatively small structure of wearable smart terminals, it is impossible to set an array composed of multiple MICs (Microphones) for noise ...
