The startup's own stack for Africa and Middle East is now handling more than 17,000 calls per day.

Originally published on prodinit.com Key Takeaways Sub-300ms end-to-end latency is the human-conversation threshold for voice AI. The latency budget breaks into four layers: STT (80–120ms), LLM first-token (150–250ms), TTS first-chunk (60–100ms), and network transport (20–60ms). Missing target in any one layer pushes the total over 500ms. WebRTC with ICE Trickle is the correct transport for brows…

Introduction YouTube has become one of the largest sources of knowledge on the internet. From AI research discussions and startup podcasts to technical tutorials and industry analysis, creators upload hours of valuable content every single day. However, consuming all of this information manually is nearly impossible, especially for users subscribed to dozens or even hundreds of channels. To solve…

A walkthrough of building a voice AI backend — through three TTS providers, a chunking problem, Redis caching, distributed locks, and a thundering herd. The Idea I wanted to read long articles without staring at a screen. The concept was simple: paste an article, get back an MP3. Building it turned out to be an education in the real-world constraints of TTS APIs — character limits, latency, cost,…

Why Voice AI for Local Businesses Is Harder Than a Chatbot I used to think a voice AI agent was basically a chatbot with audio. User speaks. AI understands. AI replies. That was the simple version in my head. But after working on RingBooker , an AI receptionist for salons, spas, med spas, and beauty clinics, I started to see voice AI very differently. A chatbot can be useful even when it feels a …

TL;DR: We built this because we kept hitting the same frustrations. You've got only two choices today. One, you pay a platform fee to any of the 300+ voice AI companies for a comfy UI. Or you build directly on Dograh, Pipecat or LiveKit, where every prompt tweak means a code change and a redeployment. For anyone shipping for clients or any production use case, that's a constant bottleneck. We wan…

The Problem The Mem0 internship assignment was simple on the surface: build a voice-controlled local AI agent. But "voice-controlled" is where things get interesting. Mem0's core thesis is persistent memory for AI agents — agents that remember context across sessions. For that to work, the interaction layer has to be fast, natural, and frictionless. Voice is the most natural interface humans have…

I manage enterprise Voice AI deployments and recently wrote a detailed breakdown of this decision: https://www.voiceaipm.com/2026/04/webrtc-vs-sip-which-protocol-for-your.html The short version of what I've found in production: If users call from a real phone number (mobile/landline): you need SIP. No way around it - the PSTN speaks SIP. If the voice interface lives in a browser (click-to-call, w…

A warehouse picking operation is the process of collecting items from storage locations to fulfil customer orders. It is one of the most labour-intensive activities in logistics, accounting for up to 55% of total warehouse operating costs. For each order, an operator receives a list of items to collect from their storage locations. They walk to […] The post How ElevenLabs Voice AI Is Replacing Sc…
