国内语音情感研究演变分析与前瞻

The Evolution of Domestic Speech Emotion Research

因呈现简单、采集方便、特征多样等优势,语音情感应成为人机情感应用的主要方式。通过梳理我国语音情感的研究热点,明晰演变驱动因素,促进人机情感从研究走向应用。文章结合语音情感特点,确定演变依据,通过属性初筛、内容梳理、结合调研,开展递进式深研细究,形成发文数量、发文机构、作者合作群等演变过程模型,图谱呈现热点分布,深度分析热点演变驱动因素,构建演变路径,并基于演变提出研究前瞻:准确快速辨析情感是研究重点,适境情感语音融合是应用主流。

Because of the advantages of simple presentation,convenient collection and diverse features,speech emo⁃tion has become the main way of human-computer emotion application.By sorting out the research hotspots of speech emotion in China,the driving factors of evolution are clarified,and the human-com⁃puter emotion is promoted from research stage to application stage.Based on the characteristics of speech emotion,this paper determines the basis of evolution.A progressive in-depth research was carried out through attribute screening,content sorting,together with investigation and fact-finding,forming an evo⁃lutionary process model of the number of publications,publishing institutions,and author cooperation groups.A map was created to show the distribution of hotspots.By deeply analyzing the driving factors of hot spot evolution,constructs the evolution path is constructed,and the research prospects based on the e⁃volution is put forward.It is found that accurate and fast discrimination of emotion is the focus of research,and situational emotional speech fusion is the mainstream of application.
