Fish Audio

$500M

Fish Audio builds AI voice models for both creative use cases and enterprise applications, offering expressive and steerable AI voices.

A new challenger has entered the AI voice arena, and it's making some bold claims. Fish Audio, from Hanabi AI Inc., publicly launched its S1 model touting it as the "most expressive and natural TTS model on the market." The company isn't just talking a big game; it's directly targeting industry leader ElevenLabs with a price point that's a staggering 6x cheaper.

The announcement highlights significant traction for the platform. Fish Audio already boasts 20,000 active developers and a reported $5 million in annual recurring revenue (ARR), indicating substantial early adoption. This isn't a small startup whisper; it's a platform with growing momentum, aiming to democratize access to high-fidelity AI-generated speech and potentially redefine what constitutes the best AI voice.

At the core of Fish Audio S1's appeal is its promise of nuanced, emotionally rich voice generation. Users can clone their own voice for free with just 10 seconds of audio, a feature particularly attractive to content creators. One early user, a YouTuber, noted how they could "patch audio seamlessly" with their cloned voice, calling the results "scary well." This capability extends beyond simple voice replication, offering granular emotion control for everything from dynamic video voiceovers and immersive audiobooks to expressive character voices for games and empathetic conversational chatbots. The platform also supports over 30 languages, ensuring global reach for its expressive capabilities.

The New Standard for Accessible AI Audio

Fish Audio's aggressive pricing and ease of use position it as a serious disruptor in the AI audio market. While ElevenLabs has set a high bar for quality and naturalness, Fish Audio's S1 model aims to match or exceed it on expressiveness while significantly lowering the barrier to entry. Early testimonials from developers and creators are compelling, with one stating that Fish Audio "clearly outperformed ElevenLabs in voice authenticity and emotional nuance." This direct comparison, if validated by broader adoption, could reshape market expectations for best-in-class AI voice solutions.

The implications for creators and developers are substantial. High-quality, expressive AI voices are no longer solely the domain of well-funded studios. YouTubers, indie game developers, podcasters, and small businesses can now access tools that were previously out of reach, potentially transforming how digital content is produced and consumed. Fish Audio's commitment to open-source development further signals a community-driven approach, promising continuous innovation and rapid improvements.

How Fish Audio S1 Performed in 2026

Since launch, Fish Audio S1 has tracked well on independent benchmarks. In January 2026, the model ranked number 1 on TTS-Arena with an 80.9% accuracy score, the most-cited leaderboard for text-to-speech quality. In head-to-head listener preference tests, S1 beat ElevenLabs V3 by 64% to 36%. The 10-second voice cloning requirement, versus the 60 seconds ElevenLabs requires for cloning access, has become the platform's most-cited feature advantage among developers switching stacks.

2026 Update: Fish Audio S2 and Extended Benchmark Leadership

Fish Audio's competitive position strengthened further through mid-2026. The company's follow-up S2 Pro model also ranked first in third-party blind A/B testing by TextToLab, while independent benchmark tracking confirms Fish Audio held the top position on TTS-Arena from October 2025 through at least April 2026 across successive evaluation cycles. ElevenLabs maintained a higher Arena ELO ranking in the same period, reflecting its larger subscriber base and enterprise adoption rather than raw generation quality.

The practical gap between S1 and S2 Pro for most users comes down to use case. S1 handles standard voice cloning and generation with its 10-second audio requirement. S2 Pro added measurably improved naturalness scores, particularly for languages other than English and for emotionally dynamic content like audiobooks or character dialogue. Both sit well below ElevenLabs on price: Fish Audio's API rate is approximately 6x cheaper per character than ElevenLabs' comparable access tier.

StartupHub.ai rates Fish Audio at 59 out of 100 in our overall scoring, compared to ElevenLabs at 79. The gap reflects ElevenLabs' longer enterprise track record and broader integrations. Fish Audio's upward trajectory in benchmark rankings across 2025 and 2026 is measurable, and the pricing differential makes it the default choice for high-volume API users not locked into ElevenLabs' ecosystem.
