Lovable of Voice Agents
What it does
Building a voice agent is fast. Making it good takes forever. Voiceblox shortens the loop: describe what you want → AI generates the flow → test live in the browser → refine in plain language → deploy with one click. - Generate agents from a prompt - Edit visually on a canvas - Test with your mic — no deployment step - Fix responses by clicking what went wrong - Deploy directly from the app 30+ providers across LLMs, STT, TTS. Would love your feedback!

- IBI built a sub-500ms latency voice agent from scratchMar 2026 · ntik.me · ▲570
I built a voice agent from scratch that averages ~400ms end-to-end latency (phone stop → first syllable). That’s with full STT → LLM → TTS in the loop, clean barge-ins, and no precomputed responses. What moved the needle: Voice is a turn-taking problem, not a transcription problem. VAD alone fails; you need semantic end-of-turn detection. The system reduces to one loop: speaking vs listening. The two transitions - cancel instantly on barge-in, respond instantly on end-of-turn - define the experience. STT → LLM → TTS must stream. Sequential pipelines are dead on arrival for natural…
