MARS8 Text to Speech AI Models
MARS8 is not the most advanced Text-to-Speech model beating all voice AI benchmarks.
About
You've already heard this AI live while watching your favorite sport. **Introducing MARS8.** Now available to every developer as an API. MARS was built for live content like sports and news, where real-time translation can't afford mistakes. When millions are watching, **live doesn't lie.** Building for real content taught us: "No single model can win every use case." MARS8 ships as a family: → **MARS-Flash:** Lowest TTFB for real-time agents → **MARS-Pro:** Speed + fidelity for dubbing and audiobooks → **MARS-Instruct:** Director-level emotional control. → **MARS-Nano:** High-quality on-device. Language support covers 99% of the world's speaking population. **The results?** MARS8 benchmarks as the world's leading TTS model. **But there's one last thing.** MARS8 launches as the first TTS model on every major cloud: GCP, AWS, you name it. Stop being trapped by the API tax. Now go build something impossible with MARS8.
Key Features
Multi-model Family
Four specialized models (MARS-Flash, MARS-Pro, MARS-Instruct, MARS-Nano) tailored to low-latency streaming, high-fidelity dubbing/audiobooks, fine-grained emotional control, and on-device/edge deployment.
Low Latency / Real-time Performance
MARS-Flash delivers minimal time-to-first-byte for live applications (sports, news, voice agents), enabling real-time streaming voice experiences at scale.
High-Fidelity & Emotional Control
MARS-Pro and MARS-Instruct prioritize naturalness, expressive prosody and director-level control over emotion, timing and style for dubbing, audiobooks, and creative workflows.
On-device & Cloud Portability
MARS-Nano supports high-quality inference on constrained devices; the family runs natively on major clouds (AWS, GCP, etc.) to avoid vendor lock-in and reduce API tax.
Global Language Coverage & Production Benchmarks
Supports languages covering ~99% of the world's speaking population and publishes production-focused benchmarks (quality, speaker similarity, CER) for realistic evaluation.
How to Use MARS8 Text to Speech AI Models
1) Create an account or book a demo on the MARS8 site and obtain your API key. 2) Choose the appropriate model: MARS-Flash for real-time streaming, MARS-Pro for high-fidelity media, MARS-Instruct for fine emotional/control, or MARS-Nano for on-device needs. 3) Call the API with your input text, select language/voice/style parameters (and streaming vs. batch mode), and receive audio output (or audio stream) in your preferred format. 4) Integrate into your app (live broadcast pipeline, dubbing workflow, contact center agent, or embedded device), monitor latency/cost, and iterate voice/style settings for production quality.
