MiniMax Speech 2.6 HD is the flagship text-to-audio model from MiniMax, tuned for premium voiceover work, audiobooks, marketing content, and any scenario that demands maximum fidelity and vocal nuance. It ships on Replicate with the same easy REST API as the Turbo model, plus full support for 40+ languages, 300+ voices, and custom voice cloning.

Why use the HD variant?

🎙 Studio-grade prosody – crisper articulation, better breath control, and smoother phrasing than 2.6 Turbo.
🧠 Emotion intelligence – “auto” matches the tone to your script, or pick precise emotions like calm, fluent, or surprised.
🌐 Global language coverage – identical multilingual, dialect boost, and subtitle support as Turbo.
🧾 Subtitles on tap – enable subtitle_enable for sentence-timestamped .titles files (great for captions or QA).
💼 Predictable billing – $0.10 per 1,000 input tokens (token_input_count), zero cost for outputs.

Upgrading from Speech 2.0 HD?
Expect noticeably richer performances. The API schema is unchanged, but the per-character price is 4× higher. Consider offering both HD generations so customers can pick the fidelity that matches their budget.
