Brief

Fish Audio earned public praise from @GenAIisreal for its engineering discipline as it launches S2.1 Pro after a $52M Seed raise; S2.1 Pro clones voices from 5 seconds, is 2× faster than Cartesia, costs 1/6th of Eleven Labs, provides word-level control, runs in production for HeyGen/LiveKit/Retell/Sanas/OpenArt, and includes promotional free-month and cost-cut guarantees.

Why it matters

@GenAI_is_real praises Fish Audio’s professionalism and engineering discipline, claiming their expressive TTS offers word-level control at 1/6th the cost of Eleven Labs and that the team moved from open source to production-critical infrastructure (HeyGen, LiveKit, etc.) within a single year.

Key details

Source evidence

congrats to the whole fish audio team. ive collaborated with their engineers extensively and want to call out something beyond the model: the professionalism and engineering discipline of this team is genuinely exceptional. the models speak for themselves - expressive TTS with word-level control at 1/6th the cost is a real achievement - but its the people behind them that impress me most. from open source to production-critical infrastructure for HeyGen, LiveKit, and others in a single year. thank you for being such a great partner @FishAudio
