Kokoro-82M generates several times slower than Piper — since the controller pool moved onto it, every ATC reply arrived seconds late. Controllers return to distinct Piper speakers with the standard US voice (ryan) as the product default, so replies are fast again and the default sounds like before. The classroom gets an instructor-voice setting: standard US voice by default, 'random per module' (stable instructor per module), or one of ten named US/GB voices.
