This project uses IBM's Sentiment API to analyze customer feedback and Twilio's Studio Flow to create an IVR that captures user sentiment, sends it to Segment as a tracked event, and then uses this data to personalize messages sent to customers. The project also utilizes Segment's Destination Function to send personalized SMS or WhatsApp messages based on the sentiment analysis. By integrating IBM's Sentiment API with Twilio's Studio Flow and Segment's analytics capabilities, businesses can deliver targeted and relevant customer communications that foster trust and loyalty.
