Fish Audio vs Murf

They're different products

Most "X vs Y" comparisons treat both tools as direct competitors. Fish Audio and Murf aren't. Here's the actual difference:

• Fish Audio is a voice cloning model + cheap API. Built for creators who want to clone a voice and developers who need TTS in a product.
• Murf is a polished web editor with a library of pre-made professional voices. Built for marketers and L&D teams who write scripts and want voiceover without a recording booth.

Pick based on the job, not the brand.

When to pick Fish Audio

• You want to clone your own voice (or a brand voice)
• You're building a product that needs TTS in the API
• You generate a lot of audio and the cost matters
• You want emotion control (inline `[laugh]`, `[whisper]`, `[excited]` tags)
• You need cross-lingual generation (record once in English, output in Japanese)
• You want the option to self-host

The S2 model is open-source under Apache 2.0 (March 2026), ranks #1 on TTS-Arena, and beat ElevenLabs V3 60/40 in published blind tests. The free tier includes 8,000 credits per month with voice cloning — no card required.

When to pick Murf

• You write scripts and need polished voiceover for marketing video
• You want professional stock voices and don't care about cloning
• You're on a corporate L&D or marketing team that values an editor with timeline, pauses, and emphasis
• You need browser-based collaboration with reviewers
• You produce explainers, training, or onboarding videos

Murf's editor is genuinely better for the marketing-video workflow than Fish Audio's. The library of 120+ professional voices is curated for business content.

Quality comparison

Fish Audio S2:

• #1 on TTS-Arena
• 0.515 on Audio Turing Test
• Lowest WER on Seed-TTS Eval
• Beat ElevenLabs V3 60/40 in published blind A/B

Murf:

• Solid quality across its 120+ voices
• No public benchmark presence
• Stock voices are well-engineered for clarity and listener comfort, not benchmark fidelity

For raw quality, Fish Audio wins. For "does this voice sound right for our brand video," Murf's curated library may serve you better than picking from a smaller, less-curated set.

Pricing

Fish Audio:

• Free: 8K credits/mo + voice cloning
• Plus: $11/mo (200 min, commercial, cloning, API)
• Pro: $75/mo
• API: ~$15 per 1M characters

Murf:

• Free: limited
• Creator: ~$29/mo
• Business: ~$79/mo
• API: ~$100 per 1M characters

Fish Audio is roughly 6-7× cheaper across the board. For Murf to be worth the premium, you have to value the editor and stock library enough to pay for them.

Voice cloning

Fish Audio:

• 15-second sample
• Cross-lingual: record in English, output in 30+ languages
• Inline emotion tags
• S2 is what powers the cloning — published #1 quality

Murf:

• Available on higher tiers, limited
• Not the product's focus
• Quality trails dedicated cloning tools

If voice cloning is on your requirements list at all, Fish Audio wins this category.

API

Fish Audio:

• OpenAI-compatible
• ~$15 per 1M characters
• Streaming, WebSocket, self-hostable
• 200-400ms first-byte latency

Murf:

• REST API on Business+ tiers
• ~$100 per 1M characters
• Designed for batch generation, not live agents
• Higher latency

For any product integration, Fish Audio is the better API.

The honest take

Fish Audio and Murf rarely show up in the same buying decision once you understand what each is for. If you came here Googling "Murf alternatives" because the editor isn't a fit or the price is too high — Fish Audio's probably the answer. If you came here because you write marketing scripts and Fish Audio's API-first product feels overkill — Murf's probably the answer.

For most readers of this site (solo creators, podcasters, indie developers, content teams), Fish Audio is the right pick.
