Emotion & Prosody Control (MiniMax)

await replicate.run("minimax/speech-2.8-turbo", {
  input: {
    text: "I am absolutely thrilled with these results!",
    voice: "Lively_Girl",
    emotion: "happy",    // auto, happy, sad, angry, fearful, disgusted, surprised
    speed: 1.2,          // 0.5–2.0 (default 1.0)
    pitch: 5,            // -12 to +12 semitones (default 0)
    volume: 0,           // -6 to +6 dB (default 0)
    language: "en-US",   // 40+ language codes
  },
});

Voice Cloning

Chatterbox (5-second sample)

await replicate.run("resemble-ai/chatterbox-turbo", {
  input: {
    text: "Content to speak in the cloned voice",
    audio_prompt: referenceAudioDataURI, // 5+ seconds WAV/MP3
    temperature: 0.7, // 0.1–1.0 (higher = more variation)
  },
});

MiniMax Voice Cloning (Dedicated)

await replicate.run("minimax/voice-cloning", {
  input: {
    audio_sample: referenceAudioDataURI, // High-quality sample
  },
}); // Returns custom voice_id for use in speech models

Voice Design (Qwen TTS)

Create a voice from natural language description — no sample needed:

await replicate.run("amphion/qwen3-tts", {
  input: {
    text: "Content to speak",
    tts_mode: "voice_design",
    voice_description: "A warm, friendly female voice with a slight British accent",
    temperature: 0.8,
  },
});

ElevenLabs Parameters

await replicate.run("elevenlabs/el-multilingual-v3", {
  input: {
    text: "Content to speak",
    voice_id: "21m00Tcm4TlvDq8ikWAM", // Rachel
    model_id: "eleven_multilingual_v2",
    stability: 0.5,        // 0–1 (higher = more consistent)
    similarity_boost: 0.5, // 0–1 (higher = closer to original voice)
    style: 0.0,            // 0–1 (style exaggeration)
    use_speaker_boost: true,
  },
});

macOS Offline Fallback: say

macOS ships 30+ built-in neural voices via the say command. Instant, offline, zero-cost:

say "Hello from Alex"
say -f document.txt
say -o output.m4a --data-format=aac "Dream state finished"
say -v Alex "I am Alex, reading your documentation"

Integration with Studio Agents

• Video Generation: Generate narration → merge with avmerge
• Audio Memory: Store voice samples for consistent cloning
• Music Generation: Combine speech with background music
