Deep Speaker from Baidu Research - Pytorch Implementation

This is a slightly modified pytorch implementation of the model(modified Resnet + triplet loss) presented by Baidu Research in Deep Speaker: an End-to-End Neural Speaker Embedding System.

This code was tested using Voxceleb database. Voxceleb database paper shows shows 7.8% EER using CNN. But in my code can't reach that point. This code contained a lot of editable point such as preprocessing, model, scoring(length nomalization and file processing) and etc.

I hope this code helps researcher reach higher score.

Also, use the part of code:

• liorshk's git repository
  • Baseline code - Facenet pytorch implimetation
• hbredin's git repository
  • Voxceleb Database reader

Features

• In test, length normalization
  • This means extracting many input from single wave and averaging. This makes the results slightly better.
• In training, except pandas and preloading list.
  • This makes different training accuracy each epoch, but it does not matter.

To do list

Work accomplished so far:

• Model implementation

• Data pipeline implementation - "Voxceleb"(Please note:Pytorch dataloader is so weak(High-load preprocessing and many thread))

• Code cleanup

• Modified preprocessing

• Modified model

• Modified scoring
