摘要:

传统的自动情感识别方法依赖于手工特征的应用。然而,最近深度学习的出现使算法能够自动学习输入数据的有意义的表示。在本文中,我们研究了从大型文本和音频语料库中学习到的知识转移到自动情感识别任务中的适用性。为了评估我们的方法的实用性,我们参加了今年的Interspeech ComparE老年人情感子挑战赛,其目标是根据演讲者的情感对老年人的口语叙述进行分类。我们的研究结果表明,学习到的特征表示可以有效地应用于从口语中分类情感。我们发现,从音频信号中提取的特征的性能不如从成绩单中提取的特征的性能一致。虽然声学特性在开发集上取得了同类最佳的结果,但与基线系统相比,它们的性能在挑战的测试集上大幅下降。然而,从文本形式中提取的特征在两个集合上都显示出有希望的结果,并且在未加权平均召回率上超过官方基线5.7个百分点。

英文摘要:

Traditional approaches to automatic emotion recognition are relying on the application of handcrafted features. More recently however the advent of deep learning enabled algorithms to learn meaningful representations of input data automatically. In this paper, we investigate the applicability of transferring knowledge learned from large text and audio corpora to the task of automatic emotion recognition. To evaluate the practicability of our approach, we are taking part in this year's Interspeech ComParE Elderly Emotion Sub-Challenge, where the goal is to classify spoken narratives of elderly people with respect to the emotion of the speaker. Our results show that the learned feature representations can be effectively applied for classifying emotions from spoken language. We found the performance of the features extracted from the audio signal to be not as consistent as those that have been extracted from the transcripts. While the acoustic features achieved best in class results on the development set, when compared to the baseline systems, their performance dropped considerably on the test set of the challenge. The features extracted from the text form, however, are showing promising results on both sets and are outperforming the official baseline by 5.7 percentage points unweighted average recall.
