What it does

It's a chatbot that freestyles to user input by rhyming a few bars of generated lyrics to whatever the user feeds it.

How we built it

The chatbot is based on a python backend that generates unique lyrics based on our 15,000+ entries database of recent and old-school rap lyrics. Rhyming line endings are created by phonetically matching the user input to a set of rhyming words. The lyrics are then generated using reverse-fed markov chains that create lines of text backwards to ensure a consistent rhyming pattern.

The database was fed using a Java program, consuming a public music API. The user interacts with the chatbot through a custom built Angular front-end that takes user input and interacts with our API middle-layer and then displays the generated lyrics. The whole project was deployed on a DigitalOcean droplet and is available at http://138.68.103.192/ .

Challenges we ran into

Rap lyrics are proprietary and therefore most music APIs require decent amounts of authentication or only expose limited artists or only excerpts of lyrics per song.
