About

Gradium is a voice AI platform for developers and organizations building speech-enabled applications and conversational agents. Its hosted APIs provide streaming text-to-speech, speech-to-text, speech translation, and speech-to-speech, with WebSocket and REST interfaces, real-time turn detection, pronunciation controls, and voice design or cloning features. A browser-based studio lets users try the models and manage voices, while documentation and SDK guides support application development. Use cases include voice agents, customer-service automation, live transcription, multilingual voice experiences, and spoken content generation. Gradium also publishes Phonon, an open-weight text-to-speech model designed for local, offline use in applications and on-device systems. Plans use credits for speech generation, transcription, and translation.

About

Layercode is a cloud-based developer platform that makes it easy to build production-ready, low-latency voice AI agents by handling the real-time infrastructure so you can focus on your agent’s logic; it manages WebSockets, voice activity detection, global edge deployment, and voice model integrations while giving you full control over how your agent thinks, speaks, and responds. It enables natural, fluid voice conversations with sub-second response times and human-like turn-taking, offers observability tools so you can inspect calls, latency, and failures in production, and fits naturally into modern TypeScript and Next.js stacks with simple CLI and SDK support so you can receive text and send text back. With Layercode, you can avoid vendor lock-in by hot-swapping leading voice and transcription model providers, maintain complete flexibility by plugging in your own AI agent backend, and deploy voice agents across web, mobile, and phone interfaces.
