Struggling to build real-time voice agents because latency, multilingual support, and complex integrations slow your progress?
Gradium is a unified voice AI platform for developers that delivers ultra-low-latency text-to-speech, accurate speech-to-text (with code-switching and custom vocabulary), real-time speech-to-speech translation, and instant voice cloningโall through a single API. With on-device TTS options, bidirectional WebSocket streaming, and scalable deployment (cloud, dedicated, self-hosted, or on-prem), you can move from prototypes to production fast.
Stop Wasting Time on Voice Agent Latency
Experience low-latency streaming and high-quality voices that keep conversations natural, even under load, so users get instant responses.
Unified Translation, Transcription & Cloning
Translate and transcribe in real time, switch languages on the fly, and clone expressive voices from short samplesโwithout hopping between tools.
Go to Production with Flexible Deployments
Use Gradium in the cloud, on dedicated hardware, or offline on devices; connect via Python or Rust SDKs and major agent frameworks like LiveKit, Pipecat, and Gradbot to ship voice-enabled apps fast.

I'm building a mobile game with live NPC dialogue, and Gradium's ultra-low-latency streaming lets me push voice in sync with on-screen actions. The STT handles code-switching chats, and the on-device TTS keeps things playable offline during demos. The Bidirectional WebSocket API flows cleanly into my game loop, and setup became surprisingly straightforward after I wrapped the audio callbacks. When I hear responsive NPCs, I know I made the right choice.

What I liked
What could be better
I launched a pilot to replace our legacy TTS/STT in the support center. The standout is the Bidirectional WebSocket API, which feeds streaming audio straight into our agent UI with minimal latency. Translation and code-switching keep conversations natural across languages. Transcripts are solid, and on-device synthesis helps when agents go offline, though a few industry terms trip the model sometimes.
