Live TV with closed captions?

Don't re-transcribe captions that already exist: TV transmissions carry real closed captions (CEA-608/708). Run ccextractor on the venue's video feed and relay its live output with scripts/cc_bridge.py from the HearAura repo — exact broadcast text, no speech recognition.
