Hubert Base Ch Speech Emotion Recognition

🚀 hubert-base-ch-speech-emotion-recognition

本模型以 [TencentGameMate/chinese-hubert-base](TencentGameMate/chinese-hubert-base · Hugging Face) 作为预训练模型，在 CASIA 数据集上进行训练。CASIA 数据集提供了 1200 个由演员用中文演绎 6 种不同情感的录音样本（该数据集官网共提供 9600 条数据，我使用的数据集可能并不完整），这 6 种情感分别为：

emotions = ['anger', 'fear', 'happy', 'neutral', 'sad', 'surprise']
