In the evolving landscape of Natural Language Processing (NLP), understanding and interpreting human emotions from text remains a critical challenge, especially when dealing with transcriptions of audio content. This study proposes a novel approach to emotion detection utilizing a cutting-edge stacking ensemble learning framework. This model is designed to address the common issues in emotion detection from audio-to-text transcriptions, including the loss of emotional nuance and context during transcription. By integrating multiple machine learning algorithms and advanced feature extraction methods, our model can handle the complexities and variabilities inherent in transcribed text. Rigorous testing and validation on public datasets reveal that this ensemble approach significantly outperforms conventional methods that rely on a single algorithm, establishing a new standard for emotion detection in NLP applications.
