Henry Fellerhoff

Hey! I’m Henry, a software engineer and musician based in New York City.

I’m best known for Open IPA, an IPA transcription tool that has helped 95,615 people this year learn how to pronounce Latin and French text. I also work on Tone Sandbox, Listen Together, and Modern.fm.

I’m especially interested in music, the science of singing, sustainably-built software, climate activism, and civic tech.

If you have opportunities related to any of those (or just want to say hi) don’t hesitate to reach out!
