Embodiment Construction
[0055] In order to make the purpose, technical solution and advantages of the present invention clearer, the voice collection method and system based on voice recognition of the present invention will be further described in 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.
[0056] In one embodiment, such as figure 1 Shown, provide a kind of speech collection method based on speech recognition, this method comprises the following steps:
[0057] S100. Collect analog voice signals, where the analog voice signals include current analog voice signals and past analog voice signals.
[0058] S200, calculating a magnification factor for amplifying the current analog voice signal according to the collected current analog voice signal and past analog voice signals, to obtain the current magnification factor...

The invention provides a voice acquisition method and system based on voice recognition. The method comprises the following steps: acquiring an analog voice signal; calculating magnifying power of current analog voice signals according to acquired current analog voice signals and past analog voice signals to obtain current magnifying power; magnifying the current analog voice signals according to the current magnifying power to obtain magnified current analog voice signals; and carrying out analog-to-digital conversion on the magnified current analog voice signals to obtain current digital voice signals, and taking the current digital voice signals as input signals of voice recognition. The current magnifying power of the current analog voice signals is changed in real time, a good current magnifying power can be provided for the current analog signals, situations of signal distortion or insufficient precision of the magnified current analog voice signals are avoided, a good signal inputting foundation is provided for voice recognition, and recognition rate of voice recognition is increased.
Description
technical field [0001] The invention relates to the field of voice collection, in particular to a voice recognition-based voice collection method and system. Background technique [0002] Now speech recognition has become more and more mature, and people are also making unremitting efforts to find ways to improve the speech recognition rate. An important part of speech recognition is the collection of speech signals. The chip converts the collected analog signals into digital signals through an analog-to-digital converter, which is used as the input of the speech recognition algorithm. Therefore, the collection of voice signals is an important parameter of the voice recognition rate. Only good digital signals can provide a good foundation for the voice recognition algorithm, thereby improving the recognition rate of voice recognition. However, the traditional voice signal acquisition technology usually amplifies the collected voice signal at the same magnification when prov...
