What Is Fish Audio S2?
Fish Audio S2 is a new AI text-to-speech platform focused on realistic voice generation, voice cloning, multilingual support, and emotional voice control.
Like most modern voice AI tools, it can turn text into natural-sounding speech. But Fish Audio’s biggest selling point is the level of control it gives users over how a voice delivers a line.
Instead of simply selecting a voice and pressing generate, users can add instructions directly into the script.
For example:
[whispering]
[excited]
[speaking slowly]
[nervous laughter]
The AI then attempts to adjust its performance accordingly.
This makes the experience feel less like generating speech and more like directing a voice actor.
Our Test
The first thing that stood out was the overall quality.
If somebody played us a short English sample without revealing which platform created it, we honestly wouldn’t be confident identifying whether it came from Fish Audio or ElevenLabs.
That’s probably the biggest compliment we can give.
The voices sound natural, the pacing is good, and the emotional controls often work surprisingly well. Compared to many smaller voice AI platforms we’ve tested over the past year, Fish Audio feels much closer to the top tier.
The emotional controls are particularly interesting. Instead of applying a single emotion to an entire recording, you can influence specific parts of the script.
That opens up a lot of creative possibilities for YouTube narration, character voices, storytelling projects, educational content, and marketing videos.
The Language Question
Fish Audio proudly advertises support for more than 80 languages.
Technically, that’s true.
In practice, however, there is an important distinction between supporting a language and delivering top-tier quality in that language.
During our testing, smaller languages such as Croatian didn’t sound as polished as what we’ve become used to from ElevenLabs. We also noticed that the available voice library is heavily focused on major languages, with significantly fewer speaker options for smaller markets.
This isn’t unusual. Most AI voice companies still prioritize English and a handful of large international languages.
The difference is that Fish Audio openly promotes its extensive language support, which may lead some users to expect a more consistent experience across all languages.
That wasn’t our experience.
Where Fish Audio Really Shines
English.
This is where Fish Audio becomes genuinely impressive.
Voice quality is excellent, emotional control works well, and the generated speech often sounds remarkably natural.
More importantly, we struggled to identify a clear advantage that would justify ElevenLabs’ higher pricing for many everyday use cases.
Does ElevenLabs still have an edge?
Yes.
Its voices generally feel a little more polished and consistent, especially on longer narrations and more demanding projects.
But the gap is much smaller than we expected.
What the Community Thinks
After spending time with the platform, we checked Reddit and developer communities to see whether our experience matched what others were reporting.
For the most part, it did.
Many users praised Fish Audio’s voice quality, pricing, and multilingual capabilities. Several developers described it as one of the strongest open-source voice models currently available.
The criticism was also fairly consistent.
Some users reported that emotional instructions occasionally produce inconsistent results. Others felt that ElevenLabs still sounds slightly more natural in complex voiceover scenarios.
Interestingly, very few people seemed disappointed with the overall quality. The discussion was usually about whether Fish Audio had already caught up to ElevenLabs—not whether it belonged in the same conversation.
That’s a strong position for a relatively new platform.
The Price Advantage
Pricing is where Fish Audio becomes especially interesting.
The platform is significantly cheaper than ElevenLabs, and for developers there is also the option of self-hosting thanks to its open-source approach.
For occasional users the difference may not matter.
For teams producing hundreds of minutes of voice content every month, it definitely does.
And that’s where Fish Audio creates a compelling argument.
If the quality is approaching ElevenLabs levels while costing noticeably less, many users will at least consider making the switch.
Final Thoughts
Fish Audio S2 isn’t perfect.
The language support is not as consistent as the marketing might suggest. Smaller languages still have room for improvement, and ElevenLabs remains the more polished product overall.
But that’s not really the story here.
The story is how close Fish Audio has managed to get.
We expected a decent open-source alternative.
Instead, we found a platform that visually feels similar to ElevenLabs, offers impressive emotional controls, delivers excellent English voice generation, and costs less.
If your primary focus is English content creation, we don’t see a major reason to dismiss Fish Audio simply because ElevenLabs exists.
In fact, after testing both, we’d say Fish Audio S2 is one of the first alternatives that genuinely made us question whether the premium price of ElevenLabs is still justified for everyone. So we are giving it a 4.5 on our LMAI scale!
