About

The most comprehensive open-source voice AI platform. 24+ models, 100+ voices, all in one place.

Our Mission

TTS.ai was built on a simple belief: <strong>the best AI voice technology should be accessible to everyone</strong>. While proprietary services charge premium prices for basic text-to-speech, the open-source community has created models that match or exceed commercial quality.

We bring together the best open-source voice AI models into a single, easy-to-use platform. No vendor lock-in. No data harvesting. Just powerful voice technology at fair prices.

What We Offer

Text to Speech

24+ models including Kokoro, Chatterbox, Bark, and more. From fast lightweight synthesis to studio-quality output.

Speech to Text

Powered by Whisper, Faster-Whisper, and SenseVoice. Transcribe audio in 100+ languages with timestamps and speaker detection.

Voice Cloning

Clone any voice from a 5-second sample. Chatterbox, GPT-SoVITS, CosyVoice 2, and more. Create custom voices for your projects.

Audio Processing

Enhance audio, remove vocals, split stems, remove echo/reverb, detect key/BPM, and convert formats. All powered by AI.

Voice Chat

Real-time voice conversations with AI. Choose your model and voice for an interactive chat experience.

Developer API

OpenAI-compatible REST API. Python SDK, code examples, and comprehensive documentation. Build voice features into your apps.

Open Source First

Every model on TTS.ai is open-source, licensed under MIT or Apache 2.0. We believe in transparency and community-driven innovation.

Infrastructure

TTS.ai runs on dedicated GPU servers with NVIDIA Tesla P40 GPUs (96GB VRAM total). Our infrastructure is designed for low latency and high throughput:

  • Dedicated GPU clusters for inference - no shared resources
  • Dynamic GPU allocation based on model VRAM requirements
  • 5-queue priority system for optimal throughput
  • Models pre-loaded in VRAM for instant inference
  • CDN-backed audio delivery for fast downloads

Privacy & Security

  • <strong>No data training:</strong> We never use your audio or text to train models
  • <strong>Auto-deletion:</strong> Generated audio is automatically deleted after 24 hours
  • <strong>Encryption:</strong> All data is encrypted in transit (TLS 1.2+) and at rest
  • <strong>No tracking:</strong> We don
  • <strong>GDPR compliant:</strong> Request your data or deletion at any time

About TTS.ai FAQ

TTS.ai was built by an independent team of developers passionate about making AI voice technology accessible to everyone. We curate and serve the best open-source models from the community rather than training proprietary ones.

Our infrastructure runs on dedicated servers with NVIDIA Tesla P40 GPUs providing 96GB of VRAM. The web frontend and GPU inference servers are hosted in secure data centers with low-latency connectivity.

We minimize data storage. Text inputs are processed in real-time and not permanently stored. All uploaded and generated audio files are automatically deleted within 24 hours. We never use your data to train AI models.

TTS.ai serves a growing community of developers, content creators, and businesses worldwide. Our platform handles thousands of voice generation requests daily across 24+ AI models.

We strive for high availability with our dedicated GPU infrastructure and 5-queue priority system. While we do not offer a formal SLA for free-tier users, paid plans benefit from priority processing and higher reliability.

Yes. Every model on TTS.ai is open-source, licensed under MIT or Apache 2.0. We actively support the open-source voice AI community and contribute optimizations and integrations back to the ecosystem.

Our roadmap includes adding new state-of-the-art models as they are released, expanding language support, improving real-time voice chat capabilities, and building more audio processing tools. We continuously integrate the latest open-source voice AI advances.

We are always interested in talented developers passionate about voice AI and open-source technology. If you are interested in contributing, please reach out via our contact page.

Yes, we welcome partnerships with developers, businesses, and organizations looking to integrate voice AI into their products. Contact us to discuss API integration, volume pricing, or custom model deployment.

We conduct regular security reviews of our infrastructure. All data is encrypted in transit with TLS 1.2+, passwords are hashed with industry-standard algorithms, and API keys use one-way hashing. Server access is restricted to authorized personnel via SSH keys.

TTS.ai is GDPR compliant and follows data minimization principles. We do not store personal audio data beyond 24 hours, do not use customer data for training, and provide full data access, correction, and deletion rights upon request.

We continuously monitor the open-source voice AI landscape and add new models as they become available and prove their quality. Major model updates typically happen monthly, with minor optimizations deployed on an ongoing basis.
