Fish Audio releases expressive voice model S2.1 Pro

Fish Audio has launched S2.1 Pro, a new AI voice model designed for high emotional expressiveness. The model allows users to direct dynamic vocal cues—including laughing, whispering, and sighing—outperforming incumbents like ElevenLabs and Cartesia in emotional range while offering a 6x lower cost structure compared to ElevenLabs.

// ANALYSIS

High expressiveness and cost efficiency are driving the next phase of competition in voice AI as specialized models challenge established incumbents.

–Dynamic vocal controls like laughing and whispering significantly enhance emotional realism in synthetic speech.
–Undercutting ElevenLabs by 6x makes hyper-expressive TTS far more accessible for high-volume enterprise and developer applications.
–Rapid iterations from specialized voice labs are narrowing the feature gap with premium proprietary voice services.
