How to Build a Ai Voice Generator

// Text-to-speech with ElevenLabs voice cloning API
  async function generateSpeech(text, voiceId, options = {}) {
  const { stability = 0.5, similarity = 0.75, style = 0.5 } = options;

  const response = await fetch(
    `https://api.elevenlabs.io/v1/text-to-speech/${voiceId}`,
    {
      method: 'POST',
      headers: {
        'xi-api-key': process.env.ELEVENLABS_API_KEY,
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({
        text,
        model_id: 'eleven_multilingual_v2',
        voice_settings: { stability, similarity_boost: similarity, style }
      })
    }
  );

  // Response is audio/mpeg stream
  const audioBuffer = await response.arrayBuffer();
  return Buffer.from(audioBuffer);
  }

  // Clone a voice from audio sample
  async function cloneVoice(name, audioFile) {
  const formData = new FormData();
  formData.append('name', name);
  formData.append('files', audioFile);

  const response = await fetch('https://api.elevenlabs.io/v1/voices/add', {
    method: 'POST',
    headers: { 'xi-api-key': process.env.ELEVENLABS_API_KEY },
    body: formData
  });

  return response.json(); // returns { voice_id }
  }
