Digital Signal Processing: HMM Training and Testing with the HTK toolkit

  • Construct a digital monophone recognizer with the HTK toolkit.
  • See "problem_description.pdf" for more details.

Implementation

  • Modified from: Baseline model and script
  • In this work the following files are modified:
    • lib/proto: increase state number
    • lib/mix2_10.hed: increase number of Gaussian mixtures
    • 03_training.sh: increase training iteration
    • run.sh: an additional script that runs the whole training and testing pipeline directly
  • Implementation details are specified in "report.pdf".
  • An testing accuracy of 97.76% is achieved with this implementation.

Environment Setup

$ wget http://speech.ee.ntu.edu.tw/homework/DSP_HW2-1/htk341_debian_x86_64.tar.gz
$ tar zxvf htk341_debian_x86_64.tar.gz
Place the unzip .tar folder under the same directory as ./src
  • Or clone this repository:
$ git clone [email protected]:andi611/DSP_HTK_Toolkit.git
  • Set path for the HTK tool with script:
└── src/
    └── bash set_htk_path.sh
  • Refer to "problem_descriptiom.pdf pg.28" for more detail.

Usage

Run the whole training and testing pipeline automatically:

└── src/
    └── bash run.sh

Run each script separately:

└── src/
    ├── bash 00_clean_all.sh
    ├── bash 01_run_HCopy.sh
    ├── bash 02_run_HCompV.sh
    ├── bash 03_training.sh
    └── bash 04_testing.sh
