Collect Survey Responses with Twilio Voice, Airtable and OpenAI

This technical article provides a step-by-step guide on creating engaging phone surveys using Twilio Programmable Voice and Airtable API. The application handles incoming calls from users who dial in to participate in surveys, retrieves relevant details from Airtable, and guides them through a series of questions. The responses are recorded and automatically added as a new row in an Airtable document. Prerequisites include Node.js v16+ installed on your machine, an active Twilio account, the ngrok CLI for testing purposes, and an Airtable account. The tutorial covers setting up the server, handling incoming calls, processing gather digits, using speech recognition to fill out form fields, saving responses to Airtable, and enhancing the system with OpenAI's GPT-4 for dynamic prompts and NLP for data extraction from user responses.
