ヒント

1. 文の長さに変化をつける - 短いリアクションと長めの説明を織り交ぜます
2. リアクションを入れる - 「そのとおりです！」「興味深いですね。」「うーん。」を入れると、対話が自然になります
3. 指示は控えめに使う - 1回のやり取りにつき1つか2つにし、すべての行には入れません
4. セグメントを短く保つ - 自然なペースにするため、1ターンあたり3文未満にします
5. 声を使い分ける - 明瞭にするため、対照的な声を使います
6. 話し言葉で書く - 短縮形やくだけた言葉を使います

ワークフロー：対話＋音楽

# 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
