Audio Waveform and Word Alignments Visualization

Task Description

This project involves generating waveforms of audio files along with word alignments based on information from a CTM (Continuous Time Marked) file. The script reads the CTM file and associated audio files, and then plots the waveforms with marked word intervals.

Task Details

• Read the supplied CTM file and audio files.
• Generate waveforms for each audio file.
• Display word alignments on the waveform plots.
• Annotate words on the waveform plot.

Sample output file plot_64de11fdd1033954ee0031f4.png is provided for reference.

All reference data is available in Google Drive Folder.

Deliverables

A fully functional script (Pinnacle_ASR_Task_Script.py) for generating waveforms along with waveform output images.

Implementation

The script Pinnacle_ASR_Task_Script.py processes the CTM file and audio files to create visualizations. It utilizes Matplotlib for plotting waveforms, highlighting word intervals, and annotating words on the plot.

Usage

1. Download the script Pinnacle_ASR_Task_Script.py.

2. Install the required libraries if not already installed:

   pip install matplotlib numpy scipy
   

Outputs

1. The Waveform and the corresponding words for the Audio 1 are marked in the plot as,
2. The Waveform and the corresponding words for the Audio 2 are marked in the plot as,
