Emotion in speech is an important and challenging research area. Addition or understanding of emotions from speech is challenging. But, an equally difficult task is to identify the intended emotion from an audio or speech. Understanding emotions is important not only in itself as a research area, but also, for adding emotions to synthesised speech. Evaluating synthesised speech with emotions can be simplified if the correct factors in emotion perception can be first identified. To this end, this work explores various factors that could influence the perception of emotions. These factors include semantic information of the text, contextual information, language understanding and knowledge. This work also investigates the right framework for a subjective perceptual evaluation by providing different options to the listeners and checking which are the most effective response to evaluate the perception of the emotion. Index Terms: Emotion perception, perceptual factors, emotions in speech, emotional speech analysis/synthesis, metrics for subjective perceptual evaluations
