Systems and methods are provided for analyzing conversations between customers and call center agents in real-time. An agent may be located at an agent station having a display screen. A continuous audio feed of the conversation between a customer and an agent may be received. For every second that the customer is speaking, a customer emotion score may be calculated in real-time. A frequency at which calculated customer emotion scores equal or exceed an emotion score threshold during a specified time interval may be calculated in real-time during the conversation. The calculated frequency for the customer may be compared, in real-time, to a plurality of specified frequency thresholds. A visual representation corresponding to a highest of the plurality of specified frequency thresholds that is equaled or exceeded by the calculated frequency for the customer may be displayed in real-time on the display screen of the agent station.
