Abstract

The invention proposes a voice interaction method and system for inserting modal particles based on wav2vec, belonging to the technical fields of artificial intelligence and voice recognition. In this method, the wav2vec pre-training model under the Chinese speech environment is trained; the user's call audio is obtained and the insertion position of the modal particle is marked as the audio corpus; the audio corpus is cut, and each cut speech block is set to insert a label or not to insert Label, each speech block with a label is used as a sample to form a training sample set; an audio classification model composed of a wav2vec pre-training model and a classifier is constructed and trained, and the trained audio classification model is used to judge the human-machine speech Whether it is necessary to insert modal particles during the interaction process, the stability is high, the abruptness of random insertion is avoided, and there is no need to rely on professionals to design complex rules, with high accuracy.

Description

technical field [0001] The invention relates to the technical fields of artificial intelligence and voice recognition, in particular to a voice interaction method and system for inserting modal particles based on wav2vec. Background technique [0002] Artificial intelligence technology is becoming more and more mature. In many scenarios, robot customer service can replace manual customer service to communicate with users, reducing labor costs. However, in the prior art, human-computer voice interaction still has many deficiencies. For example, the dialogue mode of the existing customer service robot is blocking, that is, when the user is speaking, the robot will wait forever. If the user speaks a long series of sentences, the robot will remain silent and have no feedback, which greatly reduces the user's dialogue. experience. [0003] At present, some customer service robots randomly insert modal particles when the user speaks. The response effect of this kind of reply is ...
