Emotion Detection in Conversational Speech

Project Overview

In this project, we introduce an innovative approach to emotion detection in conversational speech. Utilizing a multi-modal framework that integrates both audio and textual data, our system is capable of discerning emotions within multi-speaker dialogues. This is achieved through the extraction of audio features using pre-trained models and processing of text embeddings, coupled with an attentive bi-directional GRU network. This network dynamically captures the context and the inter-speaker emotional influences.

Key Features

  • Multi-modal emotion recognition leveraging audio and text data.
  • Utilization of pre-trained models for robust audio feature extraction.
  • Implementation of an attentive bi-directional GRU for contextual understanding.
  • Evaluation on the MELD dataset, demonstrating effective emotion detection.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

  • Python 3.x
  • Pip (Python Package Installer)

Installation

  1. Clone the repository git clone https://github.com/siddhantpathakk/emotion-rnn.git
