How to stream text from LLMs using jambonz

What is LLM Streaming? In the world of Voice AI, providing a responsive, low-latency conversational experience is the holy grail. One technique that is used to minimize latency is end-to-end streaming of text and/or audio to the user.

Text-to-speech latency: the jambonz leaderboard

The emergence of AI and Large Language Models (LLMs) onto the tech landscape promises to reshape everything: how we work, how we play, and how we engage with others.

Some initial thoughts on OpenAI's Realtime API

OpenAI's Conversational interface excels - despite deficiencies in underlying Whisper speech recognition. I spent the past weekend adding support for OpenAI's Realtime API to jambonz.

FAQs

Is Jambonz Right for My Team?

Still have questions? Let’s talk it through.

Talk to an Expert

Yes. Jambonz is fully deployable anywhere—your cloud, your client’s infrastructure, or hybrid. Perfect for regulated industries and global deployments where latency or sovereignty matters.

No. Jambonz is a full-featured voice/AI orchestration platform that connects to any SIP network and plugs into any AI layer (STT, TTS, LLM). It gives you control of your call logic, media, and routing—not just a chatbot interface.

Jambonz uses flat-rate commercial licenses based on concurrent call capacity—not per-minute or per-feature fees. There are no add-on fees for services like call recording, bidrectional streaming, etc. That means predictable costs even as your usage grows 10x.

We’ve got you. Jambonz was built by telecom veterans and comes with deep observability, dev-friendly APIs, and production-ready defaults. You focus on AI workflows—we handle the voice backend.

Those platforms are SaaS-only, usage-metered, and locked into their own tech stack. You can’t self-host, swap in your preferred AI, or run in-country. Jambonz gives you full control over deployment, infrastructure, and vendor choices—so you can build voice AI that’s cost-effective, compliant, and completely yours.

We may be lean, but we’re built for reliability. Our team spans the globe and is able to offer 24x7 support. Jambonz is backed by FirstFive8 Inc.—a veteran telecom team that’s supported mission-critical infrastructure for some of the biggest platforms out there -- like Cognigy, and Amelia. Our enterprise support includes SLAs, guided onboarding, and direct access to experts who’ve seen (and solved) it all.

Yes. We offer a free, self-hosted proof-of-concept trial so your team can test real-world use cases before going live.
