The speech line moved fast through 2025 and into 2026, with the Speech-02 series arriving in April 2025, Speech 2.5 following in August, and the Speech 2.8 generation current since early 2026. The current generation supports more than 40 languages and clones a voice from roughly six to ten seconds of reference audio using a learnable speaker encoder that needs no transcript. The clips on this Index were generated with the Speech 2.8 generation, turbo tier.
