Looking at the confirmed and unconfirmed parts separately makes the conclusion clearer: what is confirmed is that the feature exists, is powered by Gemini, is exclusive to Pixel 11, and can make calls on the user's behalf; what is unconfirmed is the timing, regions, languages, authorization method, AI disclosure, privacy handling, pricing, and device scope.
Therefore, the most prudent positioning of this feature at present is: a report about a new feature, rather than a complete launch that has been verified by multiple parties. Until an official Google statement or other independent sources appear, any inference about how it will be implemented or how it will comply can only remain at the level of speculation.
