Abstract
Speech Emotion Recognition (SER) is a crucial component in the field of Human-Computer Interaction (HCI), with significant research and practical application implications. However, due to the complexity of the Tibetan language and the scarcity of datasets caused by the difficulty in collecting various dialects, there are not many research achievements in Tibetan speech recognition. Based on the foundation of constructing a TBLS1 dataset containing 6,000 Tibetan-language speech samples, an approach was devised for Tibetan speech emotion recognition. This approach leverages MFCC features and incorporates a Bi-directional Long Short-Term Memory (Bi-LSTM) network within a graph convolutional neural network. Finally, by comparing the performance of different models on this dataset, we demonstrated the feasibility of our model for Tibetan speech emotion recognition.
