This automated survey system uses Twilio's Voice and SMS capabilities to collect structured data from users over the phone or via text message. The system is built using Node.js and Express, with a MongoDB database to store survey responses. The system uses TwiML (Twilio Markup Language) to generate speech and audio prompts for the user. It also handles user input, including recorded speech and DTMF tones, and updates the survey response in real-time. The system provides a way to view survey results, including charts and tables, and allows users to play back recordings of their responses.
