Embodiment Construction

[0043] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0044] The steps shown in the flowcharts of the figures may be performed in a computer system, such as a set of computer-executable instructions. Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0045] In the prior art, because the recognition rate of the recognition engine in a large noise environment is in a low state, it is necessary to perform noise removal with a strong capability to ensure the restoration of the speech signal. However, nois...

Abstract

The invention discloses an information processing method, system, and electronic equipment, which overcomes the disadvantage that the current fixed gain for a high-volume voice signal may cause the voice amplitude to be truncated and thus reduce the voice recognition rate. The method is applied to electronic equipment. The electronic device has a voice collection unit; the method includes: obtaining a voice signal through the voice collection unit; analyzing the voice signal to obtain the environmental noise of the environment where the electronic device is located; based on the environmental noise and the preset environment The corresponding relationship between the noise level and the speech signal processing method, determining the speech signal processing method corresponding to the environmental noise; performing the first processing on the speech signal based on the speech signal processing method corresponding to the environmental noise, so that the The amplitude of the speech signal is maintained within a predetermined range. The embodiments of the present application can maximize the signal-to-noise ratio, improve speech accuracy and recognition rate.

Description

technical field [0001] The present invention relates to information processing technology, in particular to an information processing method and system, and an electronic device. Background technique [0002] Users who use electronic devices for communication will involuntarily increase their volume in a noisy environment, thereby improving the feedback on their own voice in a noisy environment. This phenomenon is called the Lombard phenomenon. [0003] In the process of realizing the present invention, the inventors of the present invention found that the prior art has at least the following technical defects. [0004] Since the gain setting needs to ensure that the amplitude of the recording signal in a normal environment is within a reasonable range, in a noisy environment, since the user's own volume will increase to a certain extent, the fixed gain may cause the voice amplitude to be truncated, thus Greatly reduces the speech recognition rate.
