Tips

1. Vary sentence length - Mix short reactions with longer explanations
2. Include reactions - "Exactly!", "Interesting.", "Hmm." make dialogue natural
3. Use directions sparingly - One or two per exchange, not every line
4. Keep segments short - Under 3 sentences per turn for natural pacing
5. Assign distinct voices - Use contrasting voices for clarity
6. Write for speaking - Use contractions, informal language

Workflow: Dialogue + Music

bashCopy code
# 1. Generate dialogue
belt app run elevenlabs/text-to-dialogue --input '{
  "segments": [
    {"text": "Welcome to the show.", "voice": "george"},
    {"text": "Great to be here.", "voice": "aria"}
  ]
}' > dialogue.json

# 2. Generate background music
belt app run elevenlabs/music --input '{
  "prompt": "Soft podcast background music, non-intrusive",
  "duration_seconds": 30
}' > music.json

# 3. Mix (no inference.sh app mixes audio; use ffmpeg locally)
curl -L -o dialogue.mp3 "<dialogue-url>"
curl -L -o music.mp3 "<music-url>"
ffmpeg -i dialogue.mp3 -stream_loop -1 -i music.mp3 -filter_complex \
  "[1]volume=0.15[bg];[0][bg]amix=inputs=2:duration=first" mixed.mp3
