Best AI Voice Generator: HeyGen vs ElevenLabs vs Cartesia vs Inworld vs Fish

Which AI voice generator creates the most realistic voice clone? I tested HeyGen Voice, Eleven v4 Turbo, Cartesia Sonic 3.6, Inworld Realtime TTS-2, and Fish Audio using the same original voice recording and an identical new test script. Hear every result without commentary over the samples, compare the voices back to back, and see how each performs across six categories: similarity, naturalness, emotion, pacing, pronunciation, and consistency. 👉 Try HeyGen: heygen.com/yt 🔔 Subscribe: https://www.youtube.com/@heygen_official?sub_confirmation=1 TOOLS TESTED: HeyGen Voice: https://www.heygen.com/ ElevenLabs — Eleven v4 Turbo: https://elevenlabs.io/ Cartesia — Sonic 3.6: https://cartesia.ai/ Inworld — Realtime TTS-2: https://inworld.ai/ Fish Audio — tested directly through Fish: https://fish.audio/ LEADERBOARD REFERENCED: Artificial Analysis Controlled Voice leaderboard: https://artificialanalysis.ai/text-to-speech/leaderboard/controlled-voice The leaderboard helped inform the lineup; this video is not a test of its exact five highest-ranked entries. Rankings and model availability can change after recording. ⁣EXACT TEST SCRIPT “I wasn’t expecting the update to arrive this quickly, but after trying it for a few days, the difference is surprisingly clear. The workflow feels faster, the results sound more natural, and small details are finally working the way they should. Is it perfect? Not quite. But this is the first version I’d genuinely feel comfortable using in a finished video.” No additional delivery prompts were used. ABOUT THE SCORING Each voice receives a subjective listening score from 0–5 in half-point increments across six categories, for a maximum of 30 points. These are the scores from this comparison—not official benchmark results or a guarantee of how a model will perform with every speaker or script. This video is published on HeyGen’s official channel. Listen to the samples and let us know which voice sounded most realistic to you before seeing the scores. Subscribe for more practical AI voice comparisons, voice-cloning tests, and HeyGen tutorials.
