About Gradium
Gradium: Expressive Real-Time Text-To-Speech
Gradium develops audio language models designed to deliver natural, expressive, and ultra-low latency voice interactions at scale. The platform provides a full suite of voice AI models, including text-to-speech, speech-to-text, and voice cloning, to power AI agents and perform various voice tasks.
Key Features
Text-to-Speech (TTS): Offers seamless real-time streaming with natural, expressive speech, mastering complex pronunciations and providing high-precision word-level timestamps for perfect text-audio synchronization.
Speech-to-Text (STT): Delivers high accuracy with controllable latency, robust performance in noisy environments, and semantic voice activity detection for smart turn-taking.
Voice Cloning: Enables instant voice cloning from just 10 seconds of audio, alongside Pro Voice Clones for fine-tuned models with high speaker similarity.
Native Multilingual Fluency: Supports English, French, Spanish, German, and Portuguese with consistent pronunciation, prosody, and seamless mid-sentence code-switching without latency.
Developer Infrastructure: Features WebSocket APIs designed for streaming, Python and Rust SDKs, and integrations with major agent frameworks like Livekit and Pipecat.
Security and Compliance: Provides private cloud options for on-premise deployments and enterprise plans featuring zero data retention.
Use Cases
Gradium is built to power AI agents and real-time applications where low latency is a strict requirement, enabling bidirectional, real-time communication and high-concurrency voice tasks.
