Say
Short, everyday phrases, picked fresh each day.
Repeat
Say each phrase three times while the front camera follows your lips.
Measure
The shape and movement of your lips, and the shape of your face, are kept as numbers.
Shape
Each take is reviewed, then used to build lip guides for SpeechPath, starting with SpeechPath 2.0, which is still in development.
Why your lips matter
SpeechPath teaches pronunciation without sound. Learners watch how lips move, then match them.
A lip guide is only as good as the lips it’s built from, and no two people speak quite alike. Every phrase you say becomes part of the guides SpeechPath is built on, starting with SpeechPath 2.0.
