ggml-small-id-q8_0.bin (264 MB): whisper.cpp. On ARM, q8_0 beats q5_0 on speed.
ct2-int8/: CTranslate2 int8_float16 for faster-whisper on GPU (T4: 106 ms per 4 s utterance, single stream). On CPU prefer whisper.cpp: faster-whisper pads every clip to 30 s.
Usage
# -ac = encoder positions: 50 per second of audio, round up to a multiple of 64 (4 s -> 256, 8 s -> 448)whisper-cli -m ggml-small-id-q8_0.bin -l id -t 4 -ac 256 -bs 1 -bo 1 -nt -f audio16k.wav

Limitations
- Test sets are read speech; conversational audio will be harder.
