End-to-end Neural Diarization with Encoder-Decoder Based Attractors trained on AMI-headset.
This example could be found at egs2/ami/diar1.
Configurations:
- Use ESPNet's default frontend to extract features. The sampling rate is 8000 Hz, with a frame length of 25 ms and a frame shift of 10 ms. The frontend extracts 23 log-scaled Mel-filterbanks.
- Use 4 layer stacked Transformer encoder, each outputs 256-dimensional frame-wise embeddings.
- Use the ESPNet' standard rnn attractor (LSTM) with hidden size of 256.
- Initial training uses data with 4 speakers for 500 epochs, following
spk4/diar_train_diar_eda_raw_spk4/config.yaml. - Adaptation involves fine-tuning the model using data with 3 and 5 speakers respectively for 20 epochs respectively, using
spk3/diar_train_diar_eda_raw_spk3/config.yamlandspk5/diar_train_diar_eda_raw_spk5/config.yamlrespectively.
RESULTS
The following results were obtained using the checkpoint spk5/diar_train_diar_eda_raw_spk5/20epoch.pth, tested on the test and development sets with the 4-speakers.
