How to Transcribe a Voice Message Using Twilio, Python, and Flask
Blog post from Twilio
This tutorial teaches developers how to transcribe voice messages using Twilio Programmable Voice and Python with Flask. To start, create a new Flask project and install necessary dependencies such as Flask, Twilio, Pyngrok, and python-dotenv. Set up a development server and authenticate against Twilio services by storing credentials in a .env file. Create an ngrok tunnel to make the local server accessible over the internet. Record an incoming call using TwiML verbs such as say, record, and hangup to control the call flow. Use the <Record> verb with optional attributes like transcribe to create a speech-to-text transcription of any message left by the caller. Finally, configure the webhook for your Twilio phone number and test the app by calling the Twilio phone number and speaking into it.
