πŸ“ž Initiate Voice Call

+

Start an automated voice chat session with a user. Miku will automatically manage containers, join voice chat, and send an invitation DM.

+ +
+

βš™οΈ Voice Call Configuration

+ +
+ +
+ + +
+ Discord ID of the user to call +
+
+ + +
+ + +
+ Discord ID of the voice channel to join +
+
+
+ + +
+ +
+ When enabled, shows voice transcriptions and responses in text channel. When disabled, voice chat is private. +
+
+ + + + + +
+ + +
+
+ + +
+

ℹ️ How Voice Calls Work

+
    +
  • Automatic Setup: STT and TTS containers start automatically
    • +
  • Warmup Wait: System waits for both containers to be ready (~30-75 seconds)
    • +
  • VC Join: Miku joins the specified voice channel
    • +
  • DM Invitation: User receives a personalized invite DM with a voice channel link
    • +
  • Auto-Listen: STT automatically starts when user joins
    • +
  • Auto-Leave: Miku leaves 45 seconds after user disconnects
    • +
  • Timeout: If user doesn't join within 30 minutes, call is cancelled
    • +
+
+ + +
