Why CAMB.AI

What Makes CAMB.AI Text-to-Speech Different?

CAMB.AI converts written text into natural, human-sounding speech across 150+ languages, covering 99% of the world's speaking population. MARS8 is the first production-grade TTS model family with purpose-built models for distinct use cases, each optimized for a specific balance of latency, fidelity, and deployment requirements. MARS-Pro achieves 0.87 WavLM speaker similarity and 0.71 CMV similarity — a 38% improvement over the nearest competitor, as measured by the MAMBA benchmark.

How It Works

From Text to Speech in Four Steps

Choose Your Model

MARS-Flash for real-time (600ms TTFB), MARS-Pro for production-grade content, MARS-Instruct for emotion-controlled output, or MARS-Nano for on-device (60ms TTFB, 60M parameters).

Integrate via API

Connect to CAMB.AI's TTS API, pass in text, select a target language (150+ available), and optionally provide a voice reference sample for cloning.

Configure Voice and Language

Select from the voice library or clone a custom voice from a short reference sample. Use dictionaries to control pronunciation and accent-specific delivery.

Deploy and Scale

Deploy via cloud API for web and server applications, or package MARS-Nano for on-device integration. Scale across languages without re-recording.

FAQs

Frequently Asked Questions

MARS8 is a family: MARS-Flash is tuned for real-time latency, MARS-Pro for maximum fidelity and speaker similarity, MARS-Instruct for emotion and prosody control, and MARS-Nano for on-device deployment on constrained hardware.

Yes. Provide a short reference sample and CAMB.AI clones the voice, letting you generate unlimited speech in that identity across any supported language while preserving timbre and delivery.

Yes. MARS-Nano is a 60M-parameter model built to run on-device with low latency and no cloud round-trip, making it suitable for IoT, wearables, and privacy-sensitive deployments.

MARS-Pro achieves 0.87 WavLM speaker similarity and 0.71 CMV similarity — a 38% improvement over the nearest competitor, as measured by MAMBA, CAMB.AI's open-sourced TTS evaluation framework.

Yes. Every model in the MARS8 family is available through a single API, so you can pass text, choose a language and voice, and stream generated speech into your product.

Yes. MARS-Instruct exposes fine-grained control over emotion, pace, emphasis, and intonation, so you can direct delivery to match tone and context.
