Inspiration

I love golf, but I don't have much time to practice. Visualization is a proven way to improve sports performance. I wanted to build a tool that I could use to prepare before rounds, and increase my performance.

What it does

Hole 0 generates personalized MP3s that help you visualize a golf course and all the shots you will take on it. It takes in a course of your choice, as well as how far you hit each club, and generates a guided meditation that walks you through the course.

How we built it

Hole 0 works like this:

• Gets a description for each hole of a golf course based on a yardage book or website
• Takes a user-input of their average yardage by club
• Passes info about the course and the player's game to GPT-4 which generates a script for a guided visualization as if it were an expert golf caddy
• Once the script is made, it gets passed to Play.HT to generate audio
• After the audio is generated, I use ffmpeg to edit it and add background music

Challenges we ran into

Working with ffmpeg and determining where to put pauses was the most difficult part.

For meditation/visualization type audio, getting proper pauses is crucial. Commercial Text-To-Speech APIs aren't that good at creating pauses right now, so I had to write a lot of custom ffmpeg code to put pauses in the right spots to make it sound natural.

Accomplishments that we're proud of

I got a working sample built in 24hrs.

What we learned

How to use ffmpeg to make AI-generated audio sound more realistic.

What's next for Hole 0

I am building a company that connects people with hypnotherapists to help them change their habits, and I plan on using some of the technology behind Hole 0 to make personalized self-hypnosis recordings for my customers.
