Overview

Fish Audio spans text-to-speech, voice cloning, speech-to-text, and voice agents. Its named uses include video voiceovers, audiobook narration, character voices, and conversational chatbots, so it can serve both content workflows and audio-enabled products. That breadth is useful when a team needs several audio capabilities together, but may be unnecessary for a single narrowly defined task.

The voice library contains more than 2,000,000 voices, and generated audio can be delivered in WAV, PCM, MP3, or Opus. A large catalog creates choice, though the practical benefit depends on finding voices that fit the intended production.

Key features

Expressive synthesis: TTS offers emotion and expression controls, real-time generation, and adjustments for speed, volume, and model parameters. Automatic support for eight languages with native accents makes it relevant to multilingual projects; the Free Tier's 500-character per-generation cap, however, limits longer passages.
Cloning and voice capacity: Voice cloning is available, with professional voice slots scaling from one on Plus to five on Pro and Max. Free users get three public voice slots, while Pro and Max include unlimited voice slots; those differences matter to creators managing multiple voices or teams maintaining a larger catalog.
Developer interfaces: The API supports generation, cloning, and transcription through REST and WebSocket streaming, with official Python and TypeScript SDKs. Connections with Vapi, Twilio, Retell, and workflow automation tools make it a candidate for voice-agent stacks, while the available interfaces give developers more than a web-only path.
Deployment and data controls: Enterprise deployments can run in VPC, on-premises, air-gapped, or sovereign-cloud environments. Default data residency is in the United States; self-hosted deployments run inside the customer's infrastructure. Enterprise contracts can enable Zero Data Retention, and qualifying healthcare workloads can use HIPAA-aligned configurations and BAAs. These options address deployment constraints, but enterprise support and compliance terms sit behind custom pricing.

Pricing

Fish Audio is freemium. Its pricing note says paid plans start at $15/mo, while the plan prices below are stated with annual billing amounts; compare the billing term and quota against expected use before committing. Monthly minutes do not roll over, so uneven workloads can waste part of a paid allowance.

Free Tier — 0.00 USD per free: Includes 8,000 credits monthly, up to 7 minutes of generation, up to 500 characters per generation, three public voice slots, and standard generation speed. It is for personal, non-commercial use, making it a way to try the service rather than a commercial production tier.
Plus — 11.00 USD per month (billed $132 billed annually): Provides 250,000 monthly credits, up to 200 minutes of generation, up to 15,000 characters per generation, unlimited public and 10 private voice slots, and one professional voice slot. It suits an individual creator moving beyond the free caps, but the stated allowance is still modest for sustained high-volume generation.
Pro — 75.00 USD per month (billed $900 billed annually): Raises the allowance to 2,000,000 credits and up to 1,620 minutes monthly, with up to 30,000 characters per generation, three included team seats, unlimited voice slots, and five professional voice slots. A seven-day money-back guarantee is included. This is the more relevant tier for collaborative or heavier workloads, though unused minutes still expire.
Max — 749.00 USD per month (billed $8988 billed annually): Includes 25,000,000 monthly credits, up to 6,250 minutes, 10 team seats, and 15 professional voice slots. It targets teams with substantial generation and seat needs; smaller projects may not use enough of the monthly allowance to justify the tier.
Enterprise — custom pricing: Offers volume pricing, pay-as-you-go organization controls, Zero Data Retention, on-premises deployment, and SOC 2 compliance. Enterprise support includes 24/7 production support, a technical account manager, and a stated 99% uptime SLA. Fish Audio says its SOC 2 Type II audit is underway, so buyers should distinguish that status from the enterprise compliance offering.

Platforms

Fish Audio supports API, Linux, macOS, self-hosted, web, and Windows use. The combination gives teams a hosted interface alongside API and self-managed deployment paths, rather than requiring every workflow to run through a single client.

Who it's for

Fish Audio is a good fit for creators producing narration or character voices, and for developers building speech, transcription, or conversational audio features. Teams that need private infrastructure or controlled data handling can consider its enterprise deployment choices. It is a weaker fit for commercial users who need a no-cost tier, or for workloads with highly variable monthly demand that would leave paid minutes unused.

Pros and cons

Pro: Synthesis, cloning, transcription, and voice-agent tools share one service, which can reduce the need to assemble separate audio products for related workflows.
Pro: REST, streaming, and official Python and TypeScript SDKs provide several routes for integrating generation and transcription into software.
Pro: Enterprise self-hosting and multiple private deployment environments give organizations options beyond standard hosted use.
Con: Free use is limited to personal, non-commercial projects, with only seven minutes of generation and 500 characters per request.
Con: Monthly minutes do not carry forward, which makes the paid quotas less forgiving for seasonal or irregular production.
Con: Plus and higher plan prices are paired with annual billing totals, so the commitment is consequential even when the headline price is monthly.

Alternatives

Choose Voice Cloning Software or AI Voice Cloning Software when comparing products specifically for cloning. For a broader comparison of generation tools, see AI Voice Generators; for synthesis-focused options, see Text-to-Speech Software.

Kits AI is another freemium API and web option, with a free tier that includes 15 conversion minutes but no voice slots or download minutes; its free-plan details make it worth considering for conversion-focused needs. VoiceStudio is a free alternative with API, desktop, web, and self-hosted platform support. CosyVoice offers free, Apache-2.0-licensed source code and models for teams prepared to self-manage them. Voicebox is another free-plan option spanning mobile, desktop, API, and self-hosted platforms. GPT-SoVITS is a free option with API, web, desktop, and self-hosted support. CereProc is a paid alternative with a 12.99 GBP per month cloud plan that includes 1,000,000 characters. Respeecher is paid, offers a free trial, and has API and web access; its starter pack costs 5.00 USD per once. OpenVoiceChanger is a free option with API, web, Windows, Linux, and self-hosted support.

Verdict

Choose Fish Audio if you need expressive voice generation alongside cloning, transcription, or voice-agent development, especially when API integration or enterprise deployment options matter. Its broad toolset and multiple interfaces are the main reasons to choose it; look elsewhere if commercial work must start at no cost or if non-rollover minutes would make your usage unpredictable.
