Relates to:

Closes #1631

Risks

Low - This plugin is self-contained and doesn't modify any existing functionality.

• API keys are required and handled securely through environment variables
• Rate limiting and error handling are implemented for all external services

Background

What does this PR do?

This PR adds a new Twilio plugin that provides voice and text interaction capabilities to Eliza through three main features:

• Speech-to-text transcription using Deepgram
• Text-to-speech generation using ElevenLabs
• SMS messaging using Twilio

What kind of change is this?

Features (non-breaking change which adds functionality)

• Adds new plugin for voice and text interactions
• Implements three new services
• Provides comprehensive testing suite

Documentation changes needed?

My changes do not require a change to the project documentation as this is a new plugin with self-contained documentation in its README.

Testing

Where should a reviewer start?

1. Review the plugin structure in plugins/plugin-twilio/src/
2. Check the service implementations:
   • services/transcription.ts for Deepgram integration
   • services/voice.ts for ElevenLabs integration
   • services/twilio.ts for SMS functionality
3. Review the test suite in test/test.ts

Detailed testing steps

1. Clone the repository
2. Copy .env.example to .env and add your API keys
3. Install dependencies: pnpm install
4. Build the project: pnpm build
5. Run tests: pnpm test

Expected results:

• SMS test should successfully send a message
• Voice test should generate an audio file
• All error handling cases should be covered
