HeyGen Voice Tops TTS Leaderboard

HeyGen is turning voice quality into a strategic advantage for its avatar platform, though the headline ranking needs careful framing.

• –The leaderboard tests English speech across the same eight cloned voices, placing HeyGen Voice ahead of Qwen-Audio-3.1-TTS-Plus and Eleven v4 Turbo. [Artificial Analysis](https://artificialanalysis.ai/text-to-speech/leaderboard/controlled-voice?accent=zh&trk=public_post_comment-text)
• –Its differentiation is expressive delivery—emphasis, pacing, emotion, and speaker identity—not merely intelligibility.
• –The model’s end-to-end integration with Avatar V could reduce the quality gaps created by stitching together separate avatar and voice vendors.
• –Developers should treat the #1 result as an early controlled benchmark, not proof of universal superiority across languages, latency, or real-time conversations.
• –HeyGen says the model is free in its platform and API, while its professional voice-cloning add-on costs $99 per month.
