Project Overview:

Objective

Our Speech Emotion Recognition (SER) project was driven by a singular goal: to revolutionize customer service. Leveraging the power of emotional analysis through SER, we aimed to equip businesses with the ability to deliver personalized and empathetic responses. This innovative approach goes beyond simply addressing issues; it strives to forge deeper customer connections, enhancing satisfaction, all while maintaining the utmost respect for privacy and transparency.

Scope

First, we meticulously collected and annotated a vast speech dataset, ensuring it met the highest standards of diversity and quality. Then, we turned our attention to training customer service representatives. This training focused on interpreting and utilizing SER insights, with the goal of enhancing their empathy and effectiveness in real-time interactions.
