Abstract

The embodiment of the invention provides a voice emotion recognition system. The problem that in the prior art, the emotional states of customer services and customers in a call center system cannot be monitored in real time is solved. The voice emotion recognition system comprises an audio feature extraction module configured to extract an audio feature vector of a voice segment in an audio stream to be recognized; a matching module configured to match the audio feature vector of the voice segment with a plurality of emotional feature models; an emotion judgment module configured to take theemotion classification corresponding to the emotion feature model with the matched matching result as the emotion classification of the voice segment; and an emotion model establishing module configured to establish a plurality of emotion feature models by pre-learning respective audio feature vectors of a plurality of preset voice segments including emotion classification tags corresponding to the plurality of emotion classifications.

Description

technical field [0001] The invention relates to the technical field of intelligent interaction, in particular to a speech emotion recognition system. Background technique [0002] The call center system refers to an operating system that uses modern communication and computer technology to automatically and flexibly handle a large number of different incoming / outgoing calls to realize service operations. With the development of the economy, the business volume of customer service interaction in the call center system is also increasing. Timely and effective tracking and monitoring of the emotional state of customer service and customers during customer service calls is of great significance for enterprises to improve their service quality. At present, most enterprises mainly rely on hiring special quality inspectors to sample and monitor call recordings. On the one hand, this will bring additional costs to the enterprise. On the other hand, due to the uncertainty of sampling...
