Fish Audio Pricing: Plans, Credits, API Rates, and Commercial Use

Fish Audio offers an AI voice generation, voice cloning, and audio foundation model platform designed for content creators, game developers, localization studios, and software engineers. Navigating Fish Audio pricing requires understanding two entirely separate cost architectures: a credit-based monthly subscription for the browser Web App, and a pay-as-you-go top-up model for the Developer API.

Evaluating Fish Audio requires analyzing monthly credit conversion rates, commercial licensing boundaries, voice slot allocations, and API concurrency thresholds to avoid unexpected billing spikes or intellectual property exposure.

Buying Path: Web App Subscriptions vs Developer API

Fish Audio divides its commercial offerings into two distinct tracks tailored to different operational workflows:

1. The Web App Creator Track (Subscriptions): Engineered for content creators, video producers, narrators, and audio designers generating speech directly through the browser. Users pay a recurring monthly or annual fee that grants a pool of generation credits, character-per-request allowances, private voice cloning slots, and commercial use rights.
2. The Developer API Track (Pay-As-You-Go): Engineered for engineering teams embedding real-time text-to-speech (TTS), speech-to-text (ASR), and generative voice design into mobile apps, interactive agents, gaming engines, and automated pipelines. Developers fund a prepaid balance and pay strictly for consumed bytes, audio hours, or generation calls, without needing an active web app subscription.

Understanding whether your workload lives in an editorial studio or inside software code is the critical first decision. Attempting to run programmatic backend workloads through consumer web app subscriptions causes rate-limiting friction, while using raw API calls for interactive script narration forces developers to build their own editing timeline.

Web App Plan Ladder and Included Entitlements

The Fish Audio Web App offers four self-serve tiers alongside customized enterprise agreements. Monthly plans provide flexibility, while annual billing delivers substantial savings (typically equivalent to two to three months free).

1. Free ($0 / month)

The Free plan is strictly an evaluation tier for testing voice naturalness, latency, and language fidelity. It provides 8,000 monthly credits (yielding approximately 7 minutes of generated speech) with a tight limit of 500 characters per individual generation. Free users can access community voices and test basic voice creation with 3 public voice slots. However, all generated audio is restricted to personal, non-commercial use. Audio generated on the Free tier cannot be monetized, used in sponsored content, or published for business purposes.

2. Plus ($9.99 / month or $8 / month billed annually)

Plus is the entry-level commercial tier for independent creators, podcasters, and solo educators. Billed at $9.99 monthly or $96 annually, it grants 250,000 monthly credits—equivalent to roughly 200 minutes (over 3 hours) of high-quality speech generation. The per-request limit expands dramatically to 15,000 characters, allowing long-form chapter generation without stitching tiny fragments. Crucially, Plus introduces private voice cloning slots and full commercial rights, permitting monetized YouTube videos, audiobooks, and commercial advertising.

3. Pro ($39.99 / month or $32 / month billed annually)

Pro is engineered for professional production teams, marketing agencies, and recurring media operations. At $39.99 monthly or $384 annually, the credit allowance scales to 2,000,000 monthly credits (approximately 1,620 minutes or 27 hours of audio). The per-request ceiling doubles to 30,000 characters. Pro introduces shared team workspaces, bundling 3 team member seats so multiple producers can share credit pools, audio histories, and branded custom voice clones under a single organization.

4. Max ($199.99 / month or $160 / month billed annually)

Max serves high-volume content studios, localization houses, and publishing operations producing continuous audio content. At $199.99 monthly or $1,920 annually, it provides 25,000,000 monthly credits (roughly 6,250 minutes or over 104 hours of generated speech) and includes 10 team seats. Max accounts receive prioritized server rendering during peak platform traffic and dedicated priority customer support.

5. Enterprise (Custom Contract)

Enterprise packages address large media conglomerates and regulated organizations requiring custom infrastructure. It provides custom credit pools, dedicated GPU clusters for guaranteed sub-second voice streaming, custom zero-data-retention agreements, on-premise model weight deployments, custom voice actor licensing agreements, and SAML-based single sign-on.

Web App Subscription Matrix

The following table details the pricing, credit allocations, audio output estimates, and feature entitlements across the Web App tiers:

Credit Conversion Math: How Credits Turn into Audio

Understanding Fish Audio credit consumption prevents unexpected mid-month exhaustion:

• Generation Consumption Rate: Standard TTS generation typically consumes approximately 600 to 625 credits per 1 minute of synthesized audio (roughly 10 credits per second of output).
• Credit Expiration: Monthly subscription credits reset on each billing cycle and do not roll over. A Pro subscriber who uses 1,000,000 of their 2,000,000 credits forfeits the remainder when the next billing cycle begins.
• Credit Add-on Packs: Subscribers who exhaust their monthly allotment before the renewal date can purchase top-up credit packs directly through the dashboard without changing their underlying subscription tier.

Developer API Pricing and Concurrency Architecture

Fish Audio’s Developer API operates on a transparent, meter-based consumption model completely divorced from the web subscription tiers. Developers deposit funds into a prepaid wallet and are billed strictly for consumed units.

API Unit Costs

• Text-to-Speech (TTS) Model s2.1-pro / s2-pro: Billed at $15.00 per 1,000,000 UTF-8 bytes. In standard English and alphanumeric text, 1 byte roughly equals 1 character, translating to approximately $0.015 per 1,000 characters (or $0.09 per minute of speech assuming ~150 words per minute).
• Text-to-Speech (TTS) Model s1 (Legacy / Efficient): Billed at $10.00 per 1,000,000 UTF-8 bytes (~$0.010 per 1,000 characters), trading micro-inflection nuances for a 33% cost reduction.
• Speech-to-Text (ASR Transcription): Billed at $0.36 per audio hour ($0.006 per audio minute), providing competitive automated speech recognition and alignment.
• Generative Voice Design: Billed at $0.01 per successful generation call, enabling programmatic creation of unique artificial vocal timbres from descriptive text prompts.

Concurrency Tiers and Rate Limits

API throughput is directly tied to a developer’s cumulative top-up balance, preventing service abuse while providing seamless scaling for funded applications:

Voice Cloning, Rights, and Commercial Boundaries

Voice cloning introduces critical legal, ethical, and operational boundaries that directly impact subscription selection:

1. Public vs Private Voice Slots: On the Free plan, created voices occupy public slots, meaning community members can discover and utilize the synthetic voice profile. Paid plans (Plus and above) provide private slots where proprietary voice samples remain strictly confidential to your account or team.
2. Speaker Consent Verification: Fish Audio requires explicit affirmative consent for voice cloning. Uploading voice samples of identifiable individuals without legal documentation violates platform terms. Enterprise agreements require auditable consent trails.
3. Commercial Output Verification: Because Free tier audio is legally restricted to personal experimentation, businesses using synthetic audio in YouTube partner channels, broadcast commercials, corporate training, or customer-facing software must maintain an active Plus, Pro, Max, or API account to prove legal commercial indemnification.

Practical Budget Decision Guide

Use the following framework to align your operational requirements with the most economical Fish Audio purchasing route:

Summary Recommendation

Solo video creators should subscribe to Plus on an annual plan ($8/month) to secure full commercial clearance and private voice slots. Multi-producer studios should choose Pro ($39.99/month) to benefit from 3 shared seats and 27 hours of generation time. Engineering organizations building apps or automated agents should bypass web subscriptions entirely and fund the Developer API to access usage-based pricing with expandable concurrency.
