## Fish Audio

Fish Audio, originally known as Fish Speech, is a voice-AI platform for turning text into natural speech. It combines text-to-speech, voice cloning and speech-to-text with emotional control, so you can tag a line as [whispering], [excited] or [sobbing] and get delivery that matches the script rather than flat narration. The voice library is enormous, with community-uploaded voices numbering in the millions across a wide range of languages.

Cloning is fast and forgiving: a short sample is enough to build a usable voice model, and it can then speak in many languages while keeping the original timbre. Fish Audio publishes powerful APIs for real-time streaming, cloning and transcription, and positions itself for enterprise work such as conversational agents, dubbing and audiobook production.

The company also keeps an open-source arm, releasing the Fish Speech model line for self-hosting, while the hosted platform adds a browser studio, avatar and image/video model integrations, and paid tiers for higher volume. Free starting tiers make it easy to evaluate before committing.

**Pricing & Plans:** Freemium: free sign-up with monthly generations, plus paid subscriptions for higher volume, commercial use and API access; enterprise pricing on request.

- **Expressive Text to Speech:** Type or paste a script and generate natural narration, with inline emotion and delivery tags such as [whispering], [angry] or [laughing].
- **Instant Voice Cloning:** Create a usable voice clone from a short audio sample and reuse it across scripts and languages.
- **Huge Voice Library:** Browse and use a large catalog of community voices covering many languages and character styles.
- **Speech to Text:** Transcribe audio with multilingual support and emotion or speaker cues for downstream editing.
- **Real-time Voice APIs:** Low-latency streaming endpoints let developers build conversational agents, dubbing pipelines and audio apps.

**Strengths:** Natural, emotionally controllable output that handles nuance well; Voice cloning works from a very short sample; Very large shared voice library plus open-source model lineage; Robust APIs for real-time streaming and developer integration

**Limitations:** Free tier is limited and top-quality usage pushes you toward paid plans; Voice cloning raises consent and impersonation risks that teams must manage; Some features and model names change quickly, so docs can lag the product

## OnAPI

OnAPI is a multi-model AI API gateway built for developers and product teams who would rather integrate once than manage a dozen vendor accounts. Instead of wiring up separate SDKs, keys, rate limits, and billing relationships for every model family, you point your code at a single base URL, authenticate with one key, and select the model you want per request. Because the interface follows common OpenAI-style conventions, existing clients and libraries can often be repointed with minimal changes.

The platform spans multiple modalities. On the text side it covers major chat and reasoning models for assistants, summarization, extraction, and code generation. Beyond language, it also brokers image generation, video generation, and audio/music style endpoints, so a single integration can serve a product that needs several kinds of output. That consolidation is the core value proposition: fewer credentials to rotate, one place to track usage, and the ability to swap a model when a better or cheaper option appears.

OnAPI describes a dual-channel routing approach, where everyday or high-volume requests can be sent through a value tier to control cost, while latency- or reliability-critical workloads can be routed through an official tier. Exact pricing and per-model rates are published on the provider's own site and can change, so check current documentation before committing to a budget. As with any independent aggregator, keep a fallback provider and verify data-handling and uptime terms for production systems.

**Pricing & Plans:** Paid, usage-based API pricing. The vendor describes value and official channel tiers with different cost and stability characteristics; exact per-model rates are listed on the OnAPI website and are subject to change, so confirm current numbers there.

- **Unified, OpenAI-compatible endpoint:** Call many different models through one base URL and one API key, so existing OpenAI-style clients and SDKs usually need only minor changes.
- **Multi-modal coverage:** Access text and reasoning models alongside image, video, and audio/music generation endpoints from the same integration.
- **Dual-channel routing:** Route routine traffic through a value tier to reduce spend, and move critical workloads to an official tier when stability matters more than cost.
- **Single-account billing and keys:** Manage credentials and usage in one place instead of juggling separate accounts, quotas, and invoices across vendors.
- **Broad model catalog:** Work with well-known families such as GPT, Claude, and Gemini plus popular image and video generators, and switch models without rebuilding your stack.

**Strengths:** One key and endpoint replace multiple vendor integrations; Covers text, image, video, and audio modalities in one place; Channel tiers let you trade cost against stability per workload; OpenAI-compatible interface keeps migration effort low

**Limitations:** As an independent aggregator, uptime and data-handling depend on a third party; Pricing and available models can change and should be verified on the site; During our check the site returned a server error, so live availability should be confirmed before relying on it
