The present invention provides a speech recognition method suitable for noisy environments, comprising: receiving the to-be-processed noisy dialogue speech uploaded by a speech collection device; performing speech enhancement processing on the to-be-processed noisy dialogue speech to extract the to-be-processed noisy dialogue speech Speech features; search for the target speech recognition parameter setting value of the noisy dialog speech to be processed from the speech recognition parameter value set according to the speech feature; send the target speech recognition parameter setting value to the voice collection device, so that the speech collection device can use the target voice according to the target voice The recognition parameter setting value performs speech recognition on the received speech data. The implementation of the invention can improve the input of voice signals through the microphone in various noisy environments, and realize high-precision automatic voice recognition.
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...
