Problems solved by technology

[0003] Among them, earphones that use microphone arrays for voice enhancement often have a large shell size, occupy a large volume, affect wearing comfort, and are not portable to store. Reducing the size of the earphone shell means that the size of the microphone array is also constantly shrinking. This degrades microphone array performance and reduces speech enhancement

Embodiment Construction

[0023] The technical solutions of the present application will be described in further detail below with reference to the drawings and embodiments.

[0024] Based on the disadvantages of using a microphone array for speech enhancement, this application proposes a speech enhancement scheme for fusion processing of out-of-ear speech and in-ear speech and an earphone designed based on the scheme.

[0025] The inventor found during the research process that the feedback active noise reduction earphones are equipped with an in-ear microphone in the ear canal, which is generally used to calculate and generate canceling sound waves. After that, it can assist in noise reduction processing. In fact, the in-ear microphone can also collect voice information in the user's ear canal at the same time. Compared with the out-of-ear microphone, the in-ear microphone has the following advantages: 1. Tightly coupled in-ear headphones worn, The in-ear microphone can isolate the ambient noise (PNC...

Abstract

The embodiment of the invention provides a voice signal enhancement processing method and an earphone. The method comprises the following steps of: acquiring a first voice signal and a second voice signal, wherein the first voice signal and the second voice signal are voice signals acquired based on a first position and a second position respectively, and the first position and the second positionare taken as an outside-ear voice signal acquisition point and an inside-ear voice signal acquisition point respectively; at least performing echo cancellation processing on the second voice signal to obtain a third voice signal; and fusing the third voice signal and the first voice signal to obtain a fourth voice signal, and outputting the fourth voice signal. The earphone comprises a first microphone, a second microphone and an audio processor. Through adoption of the voice signal enhancement processing method and the earphone, the voice of a wearer can be effectively picked up and other noises can be suppressed in complex acoustic scenes such as low signal-to-noise ratio and multi-speaker interference. Moreover, the earphone is small in size, is lighter, and is lower in production andmanufacturing costs.

Description

technical field [0001] One or more embodiments of the present application relate to the technical field of voice signal processing, and in particular, to a voice signal enhancement processing method and an earphone. Background technique [0002] With the development of information technology, the demand for voice as an interactive mode is increasing. As a portable voice pickup and playback device, earphones generally need to enhance the user's voice in order to accurately and clearly recognize the user's voice in a noisy environment. The increasing maturity of wireless and miniaturization technology makes the volume of earphones shrink continuously, and the space for placing microphones for calls is also getting smaller and smaller. [0003] Among them, earphones that use microphone arrays for voice enhancement often have a large shell size, occupy a large volume, affect wearing comfort, and are not portable to store. Reducing the size of the earphone shell means that the si...
