Rudder's robot voice keeps up with non-stop talk, skips fillers, and defaults to Male voice 5

- Speaks each sentence as soon as it's complete in the stream, not only after a pause. MEASURED: with no
  pause between sentences the model joins them with a comma, not a period, so there may be no sentence end
  for 20+ s; a long stretch (≥14 words) now also breaks at the last comma (≥8 words), and ≥35 words with no
  punctuation speaks the first 25. Short fragments (<3 words) ride along with the next chunk. On 27 s of
  speech with no pause the robot spoke at 8.4 s, 16.5 s and 24.1 s instead of silent until 21.7 s; every
  word is spoken exactly once, in order.
- Cleans what the ROBOT says (the box keeps exactly what was said): drops um/uh/erm/hmm/ah with their
  commas, collapses stuttered repeats ("the the"), tidies spacing, capitalises. Text rules only.
- Default voice: Male voice 5 (speaker 375) — the clearest by ear; the Robot voice itself stays off until
  ticked.
