This project aims to propose a unsupervised learning method to adjust boundaries(forced-alignment results) generated by any forced-alignment tools(such as Kaldi).
- python3
- pandas
- scipy
- bunch
- tensorflow 1.4+
- E-step
- For each boundary, pick up three groups of features, consisting of series of sampling points.
- Label these features with 0(too left), 1(just in time) or 2(too right).
- Train a classifier with these feature-label.
- M-step 4. Predict label of features using the trained classifier. 5. Adjust each boundary with the predicted labels of its three groups of features.
- How to pick up three groups of features for a boundary?
- How to adjust each boundary with the predicted labels?
