The most obnoxious call join trigger ever created. When someone joins your call, they get the full treatment: AI-generated voice announcements, themed sound effects, and a full-screen confetti explosion.

What happens

Every join randomly picks one of 5 themes:

Theme	SFX	Voice
WWE	Pyrotechnics + metal riff	"THE UNDEFEATED! THE UNMATCHED!"
Royal	Trumpet fanfare	"All rise! The magnificent [name] has arrived!"
Sports	Arena crowd + organ	"Number ONE in our hearts!"
Movie Trailer	Cinematic booms	"In a world where calls are boring..."
DJ Hype	Dubstep buildup + drop	"OH MY GOD! [name] IS HERE!"

Each theme also has matching emoji and subtitle in the confetti page.

Requirements

• ElevenLabs API key with text-to-speech access — set ELEVENLABS_API_KEY in your environment
• macOS (uses afplay, afinfo, open, and python3)
• Tuple with triggers enabled (Preferences > Triggers > Enable)

Setup

1. Copy the welcome-party folder to ~/.tuple/triggers/
2. Make the trigger executable: chmod +x ~/.tuple/triggers/welcome-party/participant-joined
3. Set your ElevenLabs API key: export ELEVENLABS_API_KEY="your-key-here" in your shell profile
4. Enable triggers in Tuple Preferences

How it works

• Uses ElevenLabs v3 with the Xavier voice (Dominating, Metallic Announcer) and audio tags like [screaming], [explosion], and [crowd erupts] for expressive delivery
• Sound effects were generated with ElevenLabs Sound Effects and Music Generation APIs
• Voice lines are cached by content hash in audio-cache/ so repeat announcements are instant and don't burn API credits
• The confetti page fades out and the browser tab is closed via AppleScript when audio finishes

Testing

Use the theme override to test a specific theme:

TUPLE_TRIGGER_THEME_OVERRIDE=dj-hype \
TUPLE_TRIGGER_FULL_NAME="Your Name" \
~/.tuple/triggers/welcome-party/participant-joined

Or use Tuple's built-in trigger tester: Preferences > Triggers > Test Triggers.
