How to pronounce hedra

hedra is most commonly pronounced "hed ruh" (/ˈhɛdrə/). This is one of several readings in active use; the developer community hasn't converged on a single answer.

Hedra AI — a16z-backed digital-human / talking-avatar startup (Character-3 omnimodal model; $32M Series A, May 2025; 10M+ videos generated). Name = Greek 'hedra' (ἕδρα, 'seat/base'), which standalone reads HED-ruh — Behind the Name lists [ˈhɛdrə]. STRESS: HED-ruh. No founder pronunciation on record; the HEE-druh variant (/ˈhiːdrə/) circulates by analogy with compounds like polyHEEdron / dodecaHEEdron, but for the bare name HED-ruh is the dictionary-backed reading. CONTESTED — no official guidance.

Alternate readings you might hear:

• "hee druh" /ˈhiːdrə/

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.
