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...

The invention discloses a voice recognition method, a voice recognition device and a voice control system. The voice recognition method includes the following steps that: voice signals are recognized through any two models selected from a logistic regression model, a deep-credibility network model and a hidden Markov model, so that two recognition results can be obtained; whether the two recognition results are identical is judged through comparison; if the two recognition results are identical, the third model is adopted to recognize the voice signals, and a third recognition result can be obtained; whether the third recognition result is identical with one of the two previous recognition results is judged through comparison; if the third recognition result is identical with one of the two previous recognition results, whether the identical recognition results are a correct recognition result is verified; and if the identical recognition results are the correct recognition result, the recognition result is outputted. With the voice recognition method and voice recognition device of the invention adopted, the accuracy of voice recognition can be improved. The voice recognition method and voice recognition device have interactive learning functions, so that the satisfaction degree of users can be improved. With the voice control system of the invention adopted, remote control on a controlled terminal can be realized, and the load pressure of the controlled terminal can be reduced, and user experience is excellent.
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...
