The invention provides a voice recognition method suitable for a noise environment. The voice recognition method comprises the steps of receiving to-be-processed noisy dialogue voice uploaded by voicecollection equipment; performing voice enhancement processing on the to-be-processed noisy dialogue voice to extract voice features in the to-be-processed noisy dialogue voice; searching a target speech recognition parameter set value of the to-be-processed noisy dialogue speech from the speech recognition parameter value set according to the speech features; and sending the target voice recognition parameter set value to a voice acquisition device, so that the voice acquisition device performs voice recognition on the received voice data according to the target voice recognition parameter set value. According to the embodiment of the invention, voice signals input through the microphone in various noisy environments can be improved, and high-precision automatic voice recognition is realized.
Description
technical field [0001] The invention relates to the technical field of voice recognition, in particular to a voice recognition method and device suitable for noise environments. Background technique [0002] Since the 21st century, my country's speech recognition research has developed rapidly, and a considerable number of outstanding companies have emerged, reaching the world's leading level in some fields and producing products with a high market share. It has been widely used among tourists. Currently, acoustic models based on deep neural networks have significantly improved the performance of speech recognition, especially in near-field conditions. However, far-field and reverberant speech recognition remains a challenging problem for practical applications. [0003] In the practical application environment, robust speech recognition is a common concern in the fields of signal processing and speech recognition, and it is one of the most challenging tasks in recent decad...
