Abstract

The invention provides a voice recognizing method and a voice recognizing device, as well as a neural network training method and a neural network training device, and relates to the technical field of artificial intelligence. The neural network training method comprises the following steps: acquiring sample data, wherein the sample data comprises mixed voice frequency spectra and labelling phoneme of the mixed voice frequency spectra; extracting the target voice frequency spectrum from the mixed voice frequency spectra through a first sub-network; carrying out adaptive conversion on the target voice frequency spectrum through a second sub-network, so that middle transition representation is obtained; carrying out phoneme recognition based on the middle transition representation through athird sub-network; and according to the phoneme recognition result and the labelling phoneme, updating the parameters of the first sub-network, the second sub-network and the third sub-network. With the technical scheme, the voice recognition performance under the complicated interference sound condition can be promoted.

Description

technical field [0001] The present disclosure relates to the technical field of artificial intelligence, in particular, to a neural network training method for realizing speech recognition, a neural network training device for realizing speech recognition, a speech recognition method, a speech recognition device, electronic equipment, and a computer-readable storage medium. Background technique [0002] With the development of science and technology and the substantial improvement of hardware computing capabilities, more and more speech recognition is based on deep learning technology. [0003] However, the realization of speech recognition in acoustic scenes is often limited by the variability of acoustic scenes. For example, the situation that a monophonic speech signal is interfered by non-stationary noise, such as background music or multi-speaker interference, is common in practical application scenarios. [0004] Although the introduction of deep learning technology h...
