Build self-hosted TTS APIs using HuggingFace models (Parler-TTS, F5-TTS, XTTS-v2) and create LiveKit voice agent plugins with streaming support. Use when creating production-ready text-to-speech systems that need: (1) Self-hosted TTS with full control, (2) LiveKit voice agent integration, (3) Streaming audio for low-latency conversations, (4) Custom voice characteristics, (5) Cost-effective alternatives to cloud TTS providers like ElevenLabs or Google TTS.
Build self-hosted speech-to-text APIs using Hugging Face models (Whisper, Wav2Vec2) and create LiveKit voice agent plugins. Use when building STT infrastructure, creating custom LiveKit plugins, deploying self-hosted transcription services, or integrating Whisper/HF models with LiveKit agents. Includes FastAPI server templates, LiveKit plugin implementation, model selection guides, and production deployment patterns.
Guide for creating effective prompts and instructions for LiveKit voice agents. Use when building conversational AI agents with the LiveKit Agents framework, including (1) Creating new voice agent prompts from scratch, (2) Improving existing agent instructions, (3) Optimizing prompts for text-to-speech output, (4) Integrating tool/function calling capabilities, (5) Building multi-agent systems with handoffs, (6) Ensuring voice-friendly formatting and brevity for natural conversations, (7) Iteratively improving prompts based on testing and feedback, (8) Building industry-specific agents (debt collection, healthcare, banking, customer service, front desk).
Comprehensive guide for building functional tools for LiveKit voice agents using the @function_tool decorator. Use when creating tools for LiveKit agents to enable capabilities like API calls, database queries, multi-agent coordination, or any external integrations. Covers tool design, RunContext handling, interruption patterns, parameter documentation, testing, and production best practices.
Build and review production-grade web and mobile frontends using LiveKit with Next.js. Covers real-time video/audio/data communication, WebRTC connections, track management, and best practices for LiveKit React components.
Guide for building production-ready LiveKit voice AI agents with multi-agent workflows and intelligent handoffs. Use when creating real-time voice agents that need to transfer control between specialized agents, implement supervisor escalation, or build complex conversational systems.

All tests use real implementations - no mocks:
# Start API server
cd api && python server.py
# Run API tests
cd tests && pytest test_api.py -v
# Run plugin tests
cd tests && pytest test_plugin.py -v
Multiple deployment options:
See docs/DEPLOYMENT.md for detailed guides.
The plugin is a drop-in replacement for other TTS providers:
# Instead of:
# from livekit.plugins import openai
# tts = openai.TTS()
# Use:
from melotts_plugin import TTS
tts = TTS(api_base_url="http://localhost:8000")
# Same interface, self-hosted!
