pyannote.audio How to use aTrain-core/speaker-detection with pyannote.audio:
from pyannote.audio import Pipeline
pipeline = Pipeline.from_pretrained("aTrain-core/speaker-detection")
# inference on the whole file
pipeline("file.wav")
# inference on an excerpt
from pyannote.core import Segment
excerpt = Segment(start=2.0, end=5.0)
from pyannote.audio import Audio
waveform, sample_rate = Audio().crop("file.wav", excerpt)
pipeline({"waveform": waveform, "sample_rate": sample_rate})
