Recognition of Audio and Summarizing the Emotions
摘要
This paper contains a research on recognizing and summarizing emotions from audio. This came about by integrating approaches involving noise removal to enhance signal clarity with further speech signal processing and Voice Activity Detection for extracting the required speech segments. The use of Automatic Speech Recognition facilitates the transcription of the audio content into text format, after which standard text preprocessing is carried out including lowercasing and removal of stop words. Thereafter, cues are extracted from the data using machine learning and tokenization. Summaries of emotional states are generated. Not only this approach enables efficient recognition of emotion in audio inputs, it also generates summaries that would bridge understanding across a huge variety of applications, ranging from human–computer interaction to sentiment analysis in customer feedback.
