Abstract

The invention relates to the technical field of voice recognition, and provides a dialogue type voice recognition method and system, electronic equipment and a storage medium. The dialogue type voicerecognition method comprises the steps of obtaining a dual-channel audio of dialogue type voice, and performing compression reduction and channel separation on the dual-channel audio to obtain a single-channel original audio; performing framing processing on the original audio to obtain a plurality of audio frames, and performing cutting processing on the original audio according to the energy ofeach audio frame to obtain a plurality of effective audio segments; extracting Mel cepstrum features and tone features of the effective audio segments and speaker features of channels where the effective audio segments are located, and inputting the Mel cepstrum features, tone features and speaker features into a speech recognition model to obtain recognition results of the effective audio segments; and generating a voice recognition result of the original audio according to the recognition result of each effective audio segment. According to the invention, accurate cutting of the double-channel dialogue type voice can be realized, and the dialogue type voice can be accurately recognized under the condition of shielding surrounding noise.

Description

technical field [0001] The invention relates to the technical field of speech recognition, in particular to a conversational speech recognition method, system, electronic equipment and storage medium. Background technique [0002] In the OTA (Online Travel Agency, online travel agency) industry, when a user (such as a guest) or a service provider (such as a hotel) communicates with an OTA smart customer service by phone, the OTA smart customer service needs to identify the user or service party in real time. Expressed speech information, and then make feedback responses through text understanding means. In addition, in the background of the quality inspection of customer service calls, it is necessary to accurately identify the dual-channel audio in the customer service calls in time to obtain accurate text understanding, so that quality inspectors do not need to listen carefully to the audio content, but can directly understand the audio content through the text. To improv...
