Its Speak Method loops through three stages — learn the phrases native speakers actually use, practice them until they become automatic, and apply them in real conversation with the AI Speak Tutor, which returns immediate feedback on your pronunciation and phrasing. The curriculum is created by language education experts and personalized by AI, with lessons matched to your level.

Speak flags pronunciation and phrasing problems as you speak, so you can correct habits before they set in.
Every lesson is built around the phrases and patterns native speakers use in real situations, avoiding textbook sentences and grammar drills.
