Strengths	+ Accurate batch and realtime streaming speech-to-text models + Speech Understanding API for summaries, topics, and structured insights + Built-in PII redaction, profanity filtering, and content moderation + Usage-based pricing with free credits to start	+ Full STT-LLM-TTS pipeline with turn detection and interruption handling built in + Apache 2.0 licensed with Python and Node.js SDKs + Telephony support and multi-agent handoff for complex call flows + Self-hostable or managed via LiveKit Cloud with built-in observability
Tradeoffs	− Proprietary models with no open-weight or self-hosted option − Focused on transcription and understanding rather than text-to-speech	− Tightly coupled to LiveKit's room/WebRTC infrastructure model − Running production-grade realtime media servers yourself adds significant ops burden versus using LiveKit Cloud
