Welcome to the Viseme & Speech Reference Guide! The Viseme & Speech Reference Guide is a visual guide to English sounds for audiences working on speech animation.

Things to note:

• This sheet is meant to go more in depth than the Viseme Cheat Sheet; it will  move beyond basic phonemes and cover important consonant blends as well as some popular English words.
• Each viseme is variable. While some visemes possess fixed characteristics required for mechanical production (e.g. b/p/m will always need the lips to close), facial actions required for each viseme will fluctuate depending on numerous factors including – but not limited to – individual facial features and speech context.
• This guide will contain a mixture of posed visemes as well as visemes from natural speech. Each will be indicated.
