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 95K people this year learn how to pronounce Latin and French text. I’ve also worked 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.
