Description

SUPER FREE TTS — A fork of HyperTTS, rebuilt so everything stays free. From AnkiVN with 💖

Free. Natural. Expressive.
Includes over 7,000 voices across languages worldwide — fast, smooth, and 100% free.

⚙️ Settings & Configuration

Go to AnkiVN Menu → Super Free TTS Settings. There are 2 tabs:

  2. Select Super Free TTS → Generate Audio Files.
  3. Choose a voice under Voice Selection (some voices support adjusting Rate and Pitch).

Method 2 — Stream audio directly while reviewing (Realtime)

  2. Paste this line into your Card Template:
    {{tts vi_VN voices=EdgeTTS: Field_Name}}
  3. Flip the card — the audio plays immediately. Zero storage space used.
⚠️ Important Note: This method requires Super Free TTS installed on your desktop Anki. If you review cards on mobile or share decks with others, audio will not play. In that case, please use Method 1 to save audio directly into the cards.

Introduction

This is the source code for the Super Free TTS add-on for Anki. This folder has been cleaned and does not contain files generated during runtime (logs, tmp, cache, etc.), making it ready to:

  • Install into the Anki addons21 directory.
  • Push directly to GitHub as a "clean" source code repository.

Key Differences from HyperTTS

Super Free TTS is a fork of HyperTTS with a focus on providing high-quality Text-to-Speech using exclusively free resources.

1. 100% Free Services

  • Removed Paid Services: All services requiring API keys or subscriptions have been removed (Alibaba, Amazon, Azure, ElevenLabs, Google Cloud, OpenAI, etc.).
  • Added Free AI Engines: Integrated powerful free engines including EdgeTTS (Microsoft), Piper TTS, Kokoro TTS (high-quality ONNX), and MMS TTS (Meta).

2. High-Performance Architecture

  • Multi-threaded Processing: Features a new UnifiedBatchExecutor and MultiEngineExecutor for asynchronous, non-blocking audio generation.
  • Service-Specific Concurrency: Intelligent worker management (e.g., EdgeTTS is capped at 3 workers to prevent IP bans while Piper can run more aggressive threads).
  • Unified Cache & Resource Monitoring: Shared caching system and RAM tracking to ensure stability during large batches.

3. Improved UI/UX

  • Unified Settings: Merged Configuration and Preferences into a single, intuitive tabbed dialog.
  • Top-Level Menu: Added an "AnkiVN" menu to the main toolbar for faster access.
  • Simplified Workflow: "Easy Mode" for quick single-note updates and "Collection Mode" for powerful batch processing.

4. Reliability & Recovery

  • Checkpoint System: Automatically saves progress during batch generation, allowing you to resume if Anki crashes or is closed.

Main Structure

  • superfreetts_addon/: Core add-on source code (Python, UI, processing logic).
  • _PROJECT_DOCUMENTATION.md: Detailed design and internal function documentation.
  • README.md: Brief description for GitHub and users.

Standard temporary files (like __pycache__, *.pyc, *.log, *.tmp) are excluded from this repository.

Installation (Anki)

  1. Ensure Anki is closed.
  2. Copy this Superfreetts folder to:
    • Windows: C:\Users\<YourUser>\AppData\Roaming\Anki2\addons21\
  3. Restart Anki; the add-on will load automatically.

Development / Contributing

  • Modify source code in the superfreetts_addon/ directory.
  • Before committing or packaging, ensure logs and temporary files are removed to keep the repository clean.
  • Unit tests are located in the tests/ directory.
