Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0042] see figure 1 As shown, the speech recognition method of the present embodiment specifically includes the following steps:

[0043] Step S10: voice signal input.

[0044] Step S11: Recognize the speech signal through any two models of the logistic regression model, the deep belief network model and the hidden Markov model respectively, and obtain two recognition results.

[0045] The identification process specifically includes the following steps, see figure 2 Shown:

[0046] Step S11-1: Preprocessing the speech signal.

[0047] Preprocessing the voice signal mainly includes sequentially sampling the voice signal, denoising, endpoint detection, pre-emphasis, windowing and framing, and other operations.

[0048] Sampling is to convert a...

Abstract

The invention discloses a voice recognition method, device and voice control system. The method includes: respectively recognizing voice signals through any two models of a logistic regression model, a deep belief network model, and a hidden Markov model, and obtaining two Recognition results; compare whether the two recognition results are the same; if not, then use a third model to recognize the speech signal to obtain a third recognition result; and compare the third recognition result with the first two recognition results Whether one of them is the same; if so, verify whether the same recognition result is a correct recognition result; if so, output the recognition result. The voice recognition method and device of the present invention have the function of interactive learning by improving the accuracy rate of voice recognition, and improve user satisfaction. The voice control system of the present invention realizes the remote control of the controlled terminal, reduces the load pressure of the controlled terminal, and provides good user experience.

Description

technical field [0001] The invention belongs to the technical field of voice recognition, and in particular relates to a voice recognition method, a voice recognition device and a voice control system. Background technique [0002] Speech recognition technology is an important means of human-computer interaction, which can be applied in various occasions such as smart home appliance control and industrial field control. [0003] However, the recognition rate of existing speech recognition technology is low, which seriously restricts the application of speech recognition technology. Contents of the invention [0004] The invention provides a speech recognition method, which solves the problem of low speech recognition rate in the prior art. [0005] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions to achieve: [0006] A speech recognition method, comprising the steps of: [0007] The speech...
