AI总结:

针对语音情感识别自发数据集稀缺且多源于受控场景的问题,本文构建并公开EMOVOME真实生活语音数据集,评估基线及Transformer模型,发现结合专家与非专家标注可提升性能,为真实情感识别提供支持。

摘要:

语音情感识别(SER)的自发数据集稀缺,且常源于实验室环境或TV节目等模拟场景,限制了其在真实场景中的应用。我们开发并公开了情感语音消息(EMOVOME)数据集,包含来自100名西班牙语使用者在消息应用上真实对话的999条语音消息,由专家和非专家标注者进行连续和离散情感标注。我们以声学特征为基线评估了独立于说话人的SER模型,并评估了基于Transformer的模型,将结果与包含表演和诱发语音的参考数据集对比,还分析了标注者和性别公平性的影响。预训练的UniSpeech-SAT-Large模型取得最高结果,在EMOVOME上3分类效价和唤醒度预测的未加权准确率(UA)分别为61.64%和55.57%,较基线模型提升10%;情感类别预测取得42.58%的UA。EMOVOME表现低于表演类的RAVDESS数据集;诱发类的IEMOCAP数据集在情感类别预测上也优于EMOVOME,但效价和唤醒度结果相近。EMOVOME结果随标注者标签变化,结合专家与非专家标注时结果更优且公平性更好。本研究强调了受控场景与真实生活场景的差距,为真实情感识别的进一步发展提供支持。

英文摘要:

Spontaneous datasets for Speech Emotion Recognition (SER) are scarce and frequently derived from laboratory environments or staged scenarios, such as TV shows, limiting their application in real-world contexts. We developed and publicly released the Emotional Voice Messages (EMOVOME) dataset, including 999 voice messages from real conversations of 100 Spanish speakers on a messaging app, labeled in continuous and discrete emotions by expert and non-expert annotators. We evaluated speaker-independent SER models using acoustic features as baseline and transformer-based models. We compared the results with reference datasets including acted and elicited speech, and analyzed the influence of annotators and gender fairness. The pre-trained UniSpeech-SAT-Large model achieved the highest results, 61.64% and 55.57% Unweighted Accuracy (UA) for 3-class valence and arousal prediction respectively on EMOVOME, a 10% improvement over baseline models. For the emotion categories, 42.58% UA was obtained. EMOVOME performed lower than the acted RAVDESS dataset. The elicited IEMOCAP dataset also outperformed EMOVOME in predicting emotion categories, while similar results were obtained in valence and arousal. EMOVOME outcomes varied with annotator labels, showing better results and fairness when combining expert and non-expert annotations. This study highlights the gap between controlled and real-life scenarios, supporting further advancements in recognizing genuine emotions.
