Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: This work presents an approach to emotion recognition of affective speech based on multiple classifiers using acoustic-prosodic information (AP) and semantic labels (SLs). For AP-based recognition, acoustic and prosodic features are extracted from the detected emotional salient segments of the input speech. Three types of models GMMs, SVMs, and MLPs are adopted as the base-level classifiers. A Meta Decision Tree (MDT) is then employed for classifier fusion to obtain the AP-based emotion recognition confidence. For SL-based recognition, semantic labels are used to automatically extract Emotion Association Rules (EARs) from the recognized word sequence of the affective speech. The maximum entropy model (MaxEnt) is thereafter utilized to characterize the relationship beten emotional states and EARs for emotion recognition. Finally, a ighted product fusion method is used to integrate the AP-based and SL-based recognition results for final emotion decision. For evaluation, 2,033 utterances for four emotional states re collected. The experimental results reveal that the emotion recognition performance for AP-based recognition using MDT achieved 80.00%. On the other hand, an average recognition accuracy of 80.92% was obtained for SL-based recognition. Finally, combining AP information and SLs achieved 83.55% accuracy for emotion recognition.
