## 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

## PlusB

PlusB describes itself as a forward-deployed engineering firm rather than a self-serve app. Its pitch is that regulated and data-sensitive organisations should not have to send their data to a third-party model provider; instead, PlusB trains, optimizes, and loads models into the customer's own cloud VPC, private cluster, or edge devices. The company advertises sub-50ms inference latency targets, aggressive token-cost optimisation, and zero data retention, meaning nothing persists after a query is executed.

The deployment catalogue is organised around six systems: real-time voice AI that can replace legacy IVRs; autonomous agents that query databases and trigger workflows; document OCR for invoices, medical charts, handwritten logs, and contracts; domain-tuned translation; private chat that answers only from a customer knowledge base; and governance tooling that applies safety gating, content filtering, and compliance logging before any query touches core systems.

The engagement model is a three-step loop — audit and scope the data landscape and compliance requirements, build and deploy the models into the target environment, then monitor and maintain them with continuous safety checks and model upgrades. PlusB highlights education, healthcare, agriculture, and enterprise as target industries, and it also publishes independent research on small language models and compute-efficient architectures with open weights on Hugging Face.

**Pricing & Plans:** Paid engagement. PlusB does not publish public list pricing; deployments are scoped per client based on infrastructure, model choice, and compliance requirements. Prospective customers are routed to a "Talk to an Engineer" / "Start a Deployment" contact flow rather than a self-serve plan page.

- **Private LLM deployment:** Models are trained, optimized, and loaded directly into your cloud VPC, private cluster, or on-premise hardware so inference never leaves your environment.
- **Zero data retention:** The company states that queries do not persist after execution, which suits workloads in regulated and privacy-sensitive sectors.
- **Six production systems:** Voice AI, autonomous agents, document OCR, domain translation, private chat, and AI governance are offered as deployable, maintained components.
- **Voice AI and IVR replacement:** Real-time phone agents targeting sub-100ms conversational latency for replacing legacy touch-tone IVR flows.
- **Ongoing monitoring and upgrades:** Engineering teams run continuous performance monitoring, safety checks, and seamless model upgrades after go-live.

**Strengths:** Deployment-first model keeps sensitive data inside the customer's own infrastructure; Covers a broad production surface — voice, OCR, agents, translation, chat, and governance — under one engineering team; Explicit zero-data-retention stance is attractive for healthcare, education, and other regulated buyers; Open research and published model weights on Hugging Face build technical credibility

**Limitations:** No self-serve signup or transparent public pricing, so evaluation requires a sales/engineering conversation; Custom on-premise and VPC deployments imply longer lead times and higher effort than plugging into a hosted API; Independent benchmarks for the advertised latency and cost claims are not published on the marketing site
