What is AI voice conversion?

AI Voice Conversion technology transforms one person's speech to sound like another person, while preserving the original emotion, timing, and intonation. Hudson AI uses deep neural networks to separate voice identity from speech content, allowing seamless voice swaps.

How is voice conversion different from TTS?

Text-to-Speech (TTS) generates speech from text input. Voice conversion takes existing speech audio and transforms the speaker's voice while keeping the original performance — the rhythm, emotion, pauses, and expression all stay intact. Voice conversion preserves the human performance; TTS creates a new one.

Does Hudson AI offer a voice conversion API?

Yes. Hudson AI provides a REST API for voice conversion. Developers can integrate speaker-to-speaker voice transformation into their applications. The API supports reference audio upload, batch processing, and multiple output formats including WAV, MP3, and FLAC.

How much reference audio is needed for voice cloning?

Hudson AI's zero-shot voice cloning requires as little as 5-10 seconds of clean reference audio. For higher fidelity, 30-60 seconds is recommended. No model fine-tuning is required — results are generated instantly after uploading the reference sample.

Is there a free trial?

Yes. Hudson AI offers a free tier that lets you try voice conversion with no credit card required. Sign up at app.hudson-ai.com to get started immediately.
