# Unsupervised malay speakers from youtube videos

10492 unique speakers with at least 75 hours of voice activities. Steps to reproduce at https://github.com/huseinzol05/malaya-speech/blob/master/data/youtube/process-youtube.ipynb

## how-to

1. Download and extract [processed-youtube.tar.gz](processed-youtube.tar.gz), each processed videos saved as pickle, `{video_name}.pkl`.

2. Each pickle file got,

- all mp3 files postprocessing using https://malaya-speech.readthedocs.io/en/latest/load-noise-reduction.html and https://malaya-speech.readthedocs.io/en/latest/load-speech-enhancement.html
- `wav_data` is directory of the audio, prune the path to proper extracted directory.
- `asr_model` is predicted using the best model that we have, `conformer-medium`, returned `(text, probability, subwords)`, https://malaya-speech.readthedocs.io/en/latest/load-stt-transducer-model-pt.html
- `classification_model` is predicted using NEMO TITANET Large speaker verification model, https://catalog.ngc.nvidia.com/orgs/nvidia/teams/nemo/models/titanet_large, with streaming speaker similarity, https://malaya-speech.readthedocs.io/en/latest/huggingface-repository.html

3. Group by similar speakers using pagerank method (scipy.sparse.linalg.gmres),
