Abstract

The invention discloses a speech recognition method. The speech recognition method is characterized by comprising the following steps: receiving an input speech signal; determining a spectrogram of the input speech signal; extracting M alternative regions from the spectrogram, wherein M is a positive integer; determining feature vectors of the M alternative regions; and recognizing the input speech signal according to the feature vectors of the M alternative regions. According to the speech recognition method and device, electronic equipment and a computer readable storage medium provided by the embodiment of the invention, the alternative regions can be determined from the spectrogram of the input speech signal, and the input speech signal is recognized according to the alternative regions, so that the performance is excellent, and an effective region of the input speech signal can also be recognized.

Description

technical field [0001] The present disclosure relates to the field of information processing, and in particular to a voice recognition method, device, electronic equipment, and computer-readable storage medium. Background technique [0002] With the advancement of speech recognition technology, applications related to speech recognition are becoming more and more abundant. For example, smart speaker devices can interact with users according to their voices, and can also be connected to the Internet as an interface for various applications. [0003] Smart speakers need to be awakened based on voice recognition technology (keyword spotting, KWS) and / or recognize various voice commands from users. Existing speech recognition technology has undergone multiple iterations, such as template matching methods, which compare the characteristics of input speech and template speech, and determine whether to wake up or recognize based on the comparison results. For example, the hidden Ma...
