speaker-segmentation-fine-tuned-callhome-spa

This model is a fine-tuned version of pyannote/segmentation-3.0 on the diarizers-community/callhome spa dataset. It achieves the following results on the evaluation set:

• —Loss: 0.5198
• —Der: 0.1745
• —False Alarm: 0.0739
• —Missed Detection: 0.0687
• —Confusion: 0.0319

Model description

This segmentation model has been trained on Spanish data (Callhome) using diarizers. It can be loaded with two lines of code:

from diarizers import SegmentationModel

segmentation_model = SegmentationModel().from_pretrained('diarizers-community/speaker-segmentation-fine-tuned-callhome-spa')

To use it within a pyannote speaker diarization pipeline, load the pyannote/speaker-diarization-3.1 pipeline, and convert the model to a pyannote compatible format:

from pyannote.audio import Pipeline
import torch

device = torch.device("cuda:0") if torch.cuda.is_available() else torch.device("cpu")


# load the pre-trained pyannote pipeline
pipeline = Pipeline.from_pretrained("pyannote/speaker-diarization-3.1")
pipeline.to(device)

# replace the segmentation model with your fine-tuned one
segmentation_model = segmentation_model.to_pyannote_model()
pipeline._segmentation.model = segmentation_model.to(device)

You can now use the pipeline on audio examples:

from datasets import load_dataset
# load dataset example
dataset = load_dataset("diarizers-community/callhome", "spa", split="data")
sample = dataset[0]["audio"]

# pre-process inputs
sample["waveform"] = torch.from_numpy(sample.pop("array")[None, :]).to(device, dtype=model.dtype)
sample["sample_rate"] = sample.pop("sampling_rate")

# perform inference
diarization = pipeline(sample)

# dump the diarization output to disk using RTTM format
with open("audio.rttm", "w") as rttm:
    diarization.write_rttm(rttm)
