With the help of Twilio and the command line, you can deliver a romantic Valentine's Day poem over the phone to your loved ones using TwiML and the Twilio CLI. To start, you need a free or paid Twilio account, the Twilio CLI, and set up your environment by logging in to your account and installing the CLI on your machine. You then create a Twilio Bin to store the script for the voice recording that will be played when you call the number. The TwiML Bin uses a text-to-speech engine called Alice to deliver the poem, which can be changed to a man's or woman's voice by specifying the dialect in the XML code. You can also send a text message along with the phone call using the Twilio CLI. With this project, you can impress your loved ones with a surprise they surely weren't expecting and explore more creative projects with Twilio.
