Speak adds Phone Speak AI call feature for Premium Plus

Phone Speak sits inside Speak's practice tab as a one-tap way to start a call, which removes the scheduling step that usually precedes a lesson. The design choice that stands out is the memory function: because the AI recalls previous calls and their context, it can pick up a thread instead of starting cold, which the company frames as the reason users no longer need to introduce themselves each time.

Beyond conversation, the feature folds in study support that is usually separate from speaking practice. The AI flags grammar and expression mistakes during the call, and after it ends it pulls out the errors and points of repeated difficulty and builds a review lesson for that user. Questions can be asked in Japanese mid-call when an English phrasing is unclear, lowering the barrier for learners who would otherwise stall.

The content is open-ended rather than tied to fixed materials or scenarios, with the company citing meeting preparation, travel memories and daily events as possible themes. Whether the memory feature makes repeated practice stickier for subscribers is likely to be the point to watch.
