voice-changer

ElevenLabs Voice Changer Transform the voice in an audio recording into a different target voice. Voice Changer (previously called Speech-to-Speech — the API endpoint and SDK methods still use the speech_to_speech / speechToSpeech name) keeps the original performance — emotion, pacing, intonation, breaths, whispers, laughs, cries — and only swaps who is speaking. Setup: See Installation Guide . For JavaScript, use @elevenlabs/* packages only. Key Facts Maximum input length: 5 minutes per request — split longer recordings into chunks and stitch the outputs. Maximum file size: 50 MB per request — compress to MP3 if your source is larger. Pricing: 1,000 characters per minute of audio processed (duration-based, not text-based). Recommended model: eleven_multilingual_sts_v2 — often outperforms eleven_english_sts_v2 even for English-only content. Quick Start Python from elevenlabs import ElevenLabs Show more
