Dynamic Time Warping for Speech Processing
Overview
Tools (functions and scripts) for performing and evaluating speech processing tasks using dynamic time warping (DTW).
Dependencies
- Cython
- python_speech_features: Used in some of the examples.
- joblib: Used to parallelize
query-by-example search in
utils/qbe.py.
Building and testing the code
- Build the Cython components:
make - Run unit tests:
make test - Clean the code:
make clean
Examples
Examples are given in the examples/ directory. The script
examples/rnd_example.py illustrates standard DTW and compares a pure Python
implementation to the Cython implementation.
The IPython notebook speech_dtw_qbe.ipynb illustrates how to do (very basic) query-by-example (QbE) search using standard DTW.
