Optimizing AI Behavior Under Uncertainty with the OUCH Heuristic

Instead of chasing marginal accuracy gains, developers can significantly improve user satisfaction by optimizing system behaviors—acting, stopping, or confirming—based on the relative 'cost' of different error types.

A Linguistic Framework for Diagnosing Voice AI Failures

Voice AI failures are not isolated bugs but systemic issues in a joint communication activity. By mapping interactions across sound, word, interaction, and mental model layers, developers can diagnose why agents fail to maintain context and user trust.

Architecting Real-Time Voice Agents with Frontier Intelligence

To achieve low-latency voice interaction with high-intelligence models, use a cascaded architecture that optimizes perception, planning, and control layers independently, employing speculative transcription, background tool-calling, and audio prefix caching.

5 Voice Agent Failure Modes You'll Hit in Production

Voice agents fail in production when they treat conversations as open-ended text rather than structured data. Success requires prioritizing sub-300ms latency, field-level unit testing, and strict normalization between LLM outputs and speech synthesis.

Reliability and Safety in Production Voice Agents

Voice agents are scaling rapidly, but with a ~10% error rate, their centralized nature creates massive blast radii. Success requires a rigorous loop of manual evaluation, cross-call pattern analysis, and continuous red teaming.

Artful Expression in Enterprise Design at ElevenLabs

Nev Flynn, Head of Design at ElevenLabs, explains how integrating specialist roles like WebGL experts and sound designers allows the company to maintain a creative, artful edge even as they scale into enterprise markets.

Superpose: Using Generative AI for Real-Life Portrait Guidance

Superpose is an iOS camera app that uses generative AI to suggest poses for portrait photography, focusing on capturing authentic moments rather than creating synthetic AI imagery.

Engineering a Voice-First AI Companion

Voice-first AI requires moving away from text-based assumptions like stable context and slow turns. Success depends on low-latency pipelines, intelligent model routing based on emotional stakes, and treating memory as a dynamic retrieval system rather than a static transcript.

Scaling AI: Moving from Lab Prototypes to Reliable Production

Moving from prototype to production requires shifting focus from 'can it be done' to building the manufacturing, infrastructure, and operational reliability needed for real-world performance.

Why Current Voice Agents Are Just Walkie-Talkies

Most modern voice agents are 'half-duplex,' meaning they cannot listen and speak simultaneously. Achieving true 'full-duplex' interaction requires moving beyond turn-taking architectures toward multi-stream models that prioritize both natural conversation flow and reasoning intelligence.

Voice Agents: Beyond Speech-to-Speech

Voice agents don't have to talk back to be useful. By leveraging speech-to-action and event-to-speech, developers can build agents that drive software interfaces, fill forms, and interact with existing application logic rather than just engaging in conversation.

Building Universal Speech-to-Speech AI Agents

Google DeepMind is shifting from cascaded speech pipelines to natively multimodal, end-to-end speech-to-speech models that balance conversational latency, reasoning intelligence, and multimodal input/output.

Securing Agentic CLIs: Lessons from PostHog's Wizard

To safely ship agentic tools that execute code, separate deterministic enforcement from probabilistic judgment. Treat your own supply chain as a potential attack vector and assume that while individual components may be innocent, their composition can create vulnerabilities.
