Will Apple have on-device TTS that is indistinguishable from a human narrator before 2027?

Prediction market on manifold. Resolves positively if Apple integrates on-device TTS before 2027 on Mac, iPhone or iPad that, in a blind test conducted by a panel of at least 4 people of my choosing, cannot be reliably distinguished from a human narrator. The market may resolve negatively without consulting a panel if the outcome of the blind test is obvious.
