ESPnet2 SPK model

`espnet/voxcelebs12_rawnet3`

This model was trained by Jungjee using voxceleb recipe in espnet.

Demo: How to use in ESPnet2

Follow the ESPnet installation instructions if you haven't done that already.

cd espnet
git checkout 0c489a83607efb8e21331a9f01df21aac58c2a88
pip install -e .
cd egs2/voxceleb/spk1
./run.sh --skip_data_prep false --skip_train true --download_model espnet/voxcelebs12_rawnet3

import numpy as np
from espnet2.bin.spk_inference import Speech2Embedding

# from uploaded models
speech2spk_embed = Speech2Embedding.from_pretrained(model_tag="espnet/voxcelebs12_rawnet3")
embedding = speech2spk_embed(np.zeros(16500))

# from checkpoints trained by oneself
speech2spk_embed = Speech2Embedding(model_file="model.pth", train_config="config.yaml")
embedding = speech2spk_embed(np.zeros(32000))
