Pi-C.A.R.D is perfect. Read it 100% as Picard, and more recognizable that LCARS.
Changing the transcription model to something a bit better or moving the mic away from the fan could help this happen.
Or just use the mouse.
That's a perfect opportunity to get better at cosplaying a Starfleet officer.
(Seriously though, a Federation-grade system would just recognize from context whether or not you meant to invoke the voice interface. Federation is full of near-AGI in simple appliances. Like the sliding doors that just know whether you want to go through them, or are just passing by.)
