Improving French Synthetic Speech Quality via SSML Prosody Control — Demo

A lightweight, static demo webpage that showcases example SSML, side-by-side audio comparisons (baseline vs. enhanced), architecture and preprocessing diagrams, and links to project resources for the research project "Improving French Synthetic Speech Quality via SSML Prosody Control."

Contents

• index.html — main demo page
• style.css — visual styles
• script.js — client-side behavior (navigation, audio handling, animations)
• architecture.png, PreprocessingPipeline.png — illustrative diagrams
• audio/ — example audio files (*_baseline.wav, *_enhanced.wav)

Quick start

1. Clone or download this repository.
2. Open the demo in your browser:
   • Option A (double-click): open index.html in your browser.
   • Option B (recommended): run a simple local server to avoid media/CORS quirks.

# Python 3
python3 -m http.server 8000
# then open http://localhost:8000

# or using npx http-server
npx http-server -p 8000
# then open http://localhost:8000

How to update demo assets

• Replace the diagrams: overwrite architecture.png and PreprocessingPipeline.png.
• Swap example audio: put new files into the audio/ folder and update the <audio> elements in index.html.
• Edit text/SSML: update the text blocks and <pre> elements in index.html.
• Optional: enable the lazy-loading behavior in script.js by uncommenting the audio lazy-load observer lines.
