Engines
Set up every engine in one place — AI, translation, speech-to-text, and voice (TTS). The tab at the top switches between the two groups.
1. AI Engine + Translation — choose your AI/LLM provider (for AI replies, FAQ, workflow generation) and the translation provider. Enter each provider's API key here.

2. Voice (TTS + Changer) — enable one or more voice engines with the switch on the right. Enabled engines rotate top → bottom (use ▲▼ to set priority); if one fails, the next is tried. Click an engine to expand its settings. Each row shows its cost model (Local GPU is free, ElevenLabs is subscription, etc.).
