Submission Guidelines

​
Opening Issues

When reporting bugs or requesting features:
  1. Check existing issues to avoid duplicates
  2. Use descriptive titles
  3. Include:
    • Model version and variant
    • Hardware configuration
    • Steps to reproduce (for bugs)
    • Expected vs. actual behavior
    • Relevant code snippets or logs
Do not report security vulnerabilities through public GitHub issues. Follow Microsoft’s security reporting guidelines instead.

​
Pull Requests

When submitting code:
  1. Fork the repository
  2. Create a feature branch
  3. Make your changes with clear commit messages
  4. Test thoroughly on your hardware
  5. Update documentation as needed
  6. Submit a PR with a detailed description
  • Keep changes focused and atomic
  • Follow existing code style and conventions
  • Add tests for new functionality

​
Responsible AI Principles

All contributions must align with Microsoft’s Responsible AI principles. Do not contribute features that enable harmful use cases.

​
Contribution Standards

Ensure your contributions:
  • Do not facilitate deepfakes or disinformation
  • Include appropriate safety guardrails
  • Maintain or improve content verification capabilities
  • Support transparency and AI disclosure
  • Respect privacy and consent principles

​
Voice Customization

To mitigate deepfake risks, voice prompts are provided in an embedded format. Users requiring voice customization should reach out to the team directly.
Contributions involving voice customization must:
  • Implement authentication and authorization
  • Include audit logging capabilities
  • Provide clear usage documentation
  • Consider consent and verification mechanisms

​
Community and Support

​
Getting Help

​
Sharing Your Work

If you build something with VibeVoice:
  • Share your project on GitHub with the vibevoice topic
  • Disclose the use of AI-generated content
  • Consider contributing improvements back to the project
  • Link to the VibeVoice project page for attribution
It is best practice to disclose the use of AI when sharing AI-generated content, in accordance with responsible AI principles.

​
Security Reporting

Microsoft takes security seriously. For security issues:
  • Do not use public GitHub issues
  • Review guidance at https://aka.ms/SECURITY.md
