The Last 5% Problem: Why Founders Can't Trust the AI Voice They Ship

Event Live Stream Link : go.foundercoho.com/livestream-8-11 📝 Event Description AI voice models are getting scary good, but sounding human in a 30-second demo is only half the story. We don't ship code straight from a raw LLM without tests, harnesses, and safety guardrails. Yet voice has no equivalent layer today, so the audio you ship sounds perfect in review—and then mangles a customer's name, a drug, a tracking number, or a date on the one line that matters most, and a deal quietly dies. At this live FounderCoHo session, we skip the high-level hype for an honest, tactical tour of the "Last 5% Problem" in voice AI. We’ll explore where these failures cluster across English, Chinese, French, and Spanish, why standard benchmarks miss them completely, and the routing-and-evaluation layer voice production is still missing, closing with a live demo. Whether you are building voice agents, AI customer service, or multimodal LLM products, you will leave with a clear playbook on how to test, red-team, and trust the AI voice you ship. 🎙️ Featured Speaker: • SOOHYUN BAE — Founder & CEO, Podonos [YC W22 / Georgia Tech ML PhD] Soohyun is the Founder & CEO of Podonos, an automated performance and analysis platform for AI voice models powered by AI and 150,000+ global evaluators.
