## 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

## Speko

The core idea is that no single speech model wins everywhere. Speko's benchmark shows six different models taking the top spot across 18 languages, and notes that a large share of models are only ever measured in English, leaving their ranking in other languages unknown. Instead of committing to one vendor, Speko routes each stage of a voice pipeline — STT, LLM and TTS — to whichever model performs best for the language your users actually speak, with measured selection and failover before the response starts.

Two commercial shapes are offered. On Speko infrastructure you pay a single bundled rate of $0.09 per minute covering all three legs. Alternatively, managed routing adds 5% on top of a provider's published rate and lets you use your own provider keys, in which case the provider bills you directly. The router is hosted at router.speko.dev with typed contracts and public OpenAPI and AsyncAPI documentation.

The platform layer targets teams that need working phone agents, not just model access. You can map a call step by step, connect calendars, CRMs, your own APIs and documentation into any step, buy a phone number, test drafts against simulated callers including adversarial ones, and score every live call against checks you write in plain language. Native integrations exist for LiveKit and Pipecat, and an MCP server exposes Speko to Claude, ChatGPT, Grok, Cursor and Claude Code. Speko states it is backed by Y Combinator and that new accounts receive $10 in credit.

**Pricing & Plans:** Two models. On Speko infrastructure, a flat $0.09 per minute bundles STT, LLM and TTS; calls bill from answer to hang-up and unanswered calls cost nothing. With managed routing, you pay the selected provider's published rate plus 5%. $10 in signup credit applies to every account. Phone numbers cost $1 setup and $2 per month for most numbers, and calls on Speko numbers add the carrier charge plus 20%.

- **Language-aware model routing:** STT, LLM and TTS are selected per language based on an independent benchmark covering 89 models across 18 languages, with pre-response failover.
- **Voice agent platform:** Design a call step by step, plug calendars, CRMs, your APIs and docs into any step, then run it with inbound, outbound and call-list support.
- **Simulated caller testing:** Draft agents are tested against simulated callers, including red-team scenarios that try to break the flow, before they go live.
- **Plain-language call scoring:** Every live call is scored against checks you write in everyday language, for example reading back a date or never quoting a price.
- **Framework and MCP integrations:** Native Gateway services for LiveKit and Pipecat, plus an MCP server for Claude, ChatGPT, Grok, Cursor and Claude Code.

**Strengths:** Independent, language-by-language benchmark rather than a single accuracy claim; Provider-neutral routing with the option to bring your own keys; Clear, simple pricing: $0.09 per minute bundled or 5% on routed provider spend; Agent platform includes phone numbers, evaluation and live call monitoring

**Limitations:** Public preview with no SLA and email-only support outside enterprise; The benchmark and model catalogue move quickly, so routing decisions need periodic review; Telephony costs sit on top of the per-minute rate, and international routes can exceed the US minimum
