Dictation was "doing better before" sentence detection was switched on for the robot voice: with
asr.endpointing.enable the server ends an utterance at every ~0.8 s pause and the next one starts fresh.
- Default (robot voice off): the speech server runs exactly as it shipped — plain streaming, no pause cutting.
- Robot voice on (High performance mode): the server is restarted with sentence detection, which speaking
sentence by sentence needs; turning the robot off restarts it without. A switch made mid-recording waits
until Stop, so a recording is never cut. A planned restart is not reported as a crash.
- Robot voice pipelined: the next sentence is synthesised while the current one plays, so the ~1 s gap
between spoken sentences is gone (same work, overlapped).
- Verified against a stand-in speech server (go -race): startup without the flag; robot on → restart with
it; robot off while recording → deferred; after Stop → restart without; 0 data races.
