TTS Arena V2

• Vote on the latest TTS models!
• Join the Discord server

This is the source code for the new version of the TTS Arena. It is built on Flask, rather than Gradio (which was used in the previous version).

V2 Migration

• Delete TTS-AGI/TTS-Arena-V2 Space.
• Rename TTS-AGI/TTS-Arena to TTS-AGI/TTS-Arena-V2 (preserves likes and discussions).
• Deploy Arena V2 to TTS-AGI/TTS-Arena-V2.
• Rename TTS-AGI/TTS-Arena-Legacy to TTS-AGI/TTS-Arena.

Result:

• TTS-AGI/TTS-Arena is the read-only legacy leaderboard.
• TTS-AGI/TTS-Arena-V2 is the new Arena.

Resource groups:

• Remove TTS-AGI/TTS-Arena-V2 and TTS-AGI/TTS-Arena-Legacy from resource groups to make them public.

Development

pip install -r requirements.txt
python app.py

Note that you will need to setup the .env file with the correct credentials. See .env.example for more information.

You will need an active deployment of the TTS Router V2 as well, hosted on a Hugging Face Space.

Deployment

The app is deployed on Hugging Face Spaces. See the .github/workflows/sync-to-hf.yaml file for more information.

Top Voters Leaderboard Feature

This feature adds a new leaderboard tab that displays the top 10 most active voters on the TTS Arena platform. It also allows users to opt out of appearing on this leaderboard if they prefer to keep their voting activity private.

Features

• New "Top Voters" tab in the leaderboard page
• User privacy control via toggle switch
• Data migration script for adding the new database field

Database Migration

Before using this feature, you need to run the database migration to add the new field. There are two ways to do this:

Option 1: Using Flask-Migrate (Recommended)

If you have Flask-Migrate set up (which TTS Arena does), run:

flask db upgrade

This will automatically apply all pending migrations including the one for this feature.

Option 2: Using Standalone Migration Script

Alternatively, you can use the standalone migration script:

python migrations/add_user_leaderboard_visibility.py

This script adds the show_in_leaderboard column to the User model in the database. It can be safely removed after the migration is complete.

How It Works

1. The leaderboard page now includes a "Top Voters" tab
2. When a user is logged in, they can toggle whether they appear in the top voters leaderboard
3. The toggle setting is saved immediately via an AJAX call
4. Only users who have opted in (default) will appear in the top voters list

Privacy Considerations

• Users are included in the leaderboard by default (opt-out approach)
• The toggle is only available to logged-in users
• The leaderboard only shows usernames, total vote counts, and join dates
• No personal information or specific voting patterns are revealed
