Gymini: what broke in the coach voice

Two waveforms, one clean and one with a burst of static at the end

Gymini is getting a real coach voice. Two to pick from, a man and a woman, and every line is recorded ahead of time and shipped inside the app. No signal needed, it works on a plane. The whole bank, both voices, about 1,500 clips each, came to under a dollar.

Here's what broke. Every clip had static at the end. I blamed the voice model first, the way you do. Turned out the newer model hands you a finished audio file, header and all, and my script was wrapping it as if it were raw samples. So the header played as a click and the footer played as static. One if-statement fixed it. The voice was fine the whole time.

One more thing I learned from listening to all of it. The encouragement lines were cut from thirty to six, and they're off by default. Nobody wants a phone telling them they look like they could go again.
