Abstract

The scheme relates to artificial intelligence, and provides an emotion recognition method, a device and a computer readable storage medium, andthe method comprises the following steps of: receiving audio data, generating a voice spectrum graph aiming at the audio data, inputting the voice spectrum graph to a first recognition module, inputting the audio data to a second recognition module, whereinthe first recognition module extracts a first feature vector by adopting a DCNN network and an RNN network which are sequentially connected the second recognition module extracts a MFCC from audio data, andthe MFCC is transformed into a second feature vector by s non-linear transformation;and the first and second feature vectors output from the first and second recognition modules are connected to form a combined feature and be input into a full connection layer and a soft Max layer in turn for emotional recognition.. By means of the scheme, the combination of the DCNN and the RNN is beneficial for simulating subtle local emotion clues, the MFCC describes voice characteristics in a short time, more emotion related features are captured through two features extraction modes, and the emotion recognition rate is improved.

Description

technical field [0001] The present invention relates to artificial intelligence, in particular to an emotion recognition method, device and computer-readable storage medium. Background technique [0002] Accident investigation is a very important step after various accidents. People need to find out the human and external causes of accidents through this step, and issue investigation reports to remind others to avoid such tragedies from happening again. In many large-scale accidents, such as air accidents, the key parties are likely to be killed in the accident, which brings great difficulties to the investigation work. Investigators had to use the wreckage at the crash site and the information in the black boxes to deduce what caused the crash. Among the black boxes used by modern aircraft, a very important content is the cockpit recording, which records all the conversations and abnormal sounds in the cockpit during the period from takeoff to accident. As for emotion rec...
