How to pronounce Orpheus

Orpheus is most commonly pronounced "or fee us" (/ˈɔːrfiːəs/). This is the widely-used reading among engineers, though edge cases exist.

Orpheus is Canopy Labs' 2025 open-source, Llama-3b-based TTS model (repo canopyai/Orpheus-TTS; HF canopylabs/orpheus-3b-*), named after the legendary Greek bard-musician. Stress on the first syllable: OR-fee-us. Non-native devs often shift stress (or-FEE-us) or read 'ph' as /p/ ('OR-pee-us'); 'ph' is /f/ and the accent stays up front. Non-obvious because the classical name is unfamiliar and 'eu' invites a false /juː/ reading — a rarer two-syllable variant OR-fyoos /ˈɔːrfjuːs/ does exist, but OR-fee-us is dominant.

Alternate readings you might hear:

• "or fyoos" /ˈɔːrfjuːs/

Pronouncing project and product names correctly avoids the small but persistent friction of being gently corrected during standups, conference Q&As, and team calls. Hearing the word a few times locks in the right reading better than reading IPA ever will.
