Voice recognition method, device and voice control system

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 o
