Serving Voice AI at Scale — Arjun Desai (Cartesia) & Rohit Talluri (AWS)
Building voice AI that scales for enterprises
In the rapidly evolving landscape of artificial intelligence, voice technologies represent one of the most promising yet challenging frontiers for business implementation. A recent technical discussion between Arjun Desai of Cartesia and Rohit Talluri of AWS revealed critical insights into how enterprises can effectively deploy voice AI at scale. Their conversation cuts through the hype to address the practical realities organizations face when implementing voice assistants and conversational AI beyond simple consumer applications.
Key Points
-
Voice AI adoption requires addressing core infrastructure challenges including latency management, system reliability, and seamless user experiences that traditional ML platforms aren't designed to handle effectively.
-
Successful enterprise voice implementation demands specialized architecture with components like real-time streaming capabilities, advanced language understanding, and context management systems working in concert.
-
The technology stack for production voice AI differs significantly from experimental environments, requiring robust monitoring, testing frameworks, and deployment strategies that can support millions of concurrent users.
-
Voice applications present unique scaling challenges across multiple dimensions including user volume, conversation complexity, domain knowledge breadth, and multi-modal integration requirements.
-
The partnership model between AWS and specialized vendors like Cartesia provides enterprises with both fundamental infrastructure and domain-specific optimization needed for effective deployment.
Expert Analysis
The most compelling insight from this discussion is how voice AI fundamentally changes the infrastructure requirements for machine learning deployments. Unlike conventional ML models that can operate with acceptable batch processing latency, voice applications demand near-instantaneous responsiveness while maintaining context across complex, multi-turn conversations.
This matters tremendously for enterprises because it explains why many initial voice AI initiatives fail to gain traction. Organizations that attempt to retrofit existing ML infrastructure for voice applications often encounter insurmountable performance issues. Voice AI requires purpose-built architectures with streaming-first design principles—not just at the model level, but throughout the entire technology stack. Companies that recognize this fundamental difference are positioning themselves to capitalize on voice as a truly transformative interface rather than merely implementing another customer service channel.
Beyond the Discussion: Real-World Implications
What the discussion didn't fully explore is how voice AI deployment strategies differ across industries. Financial services organizations, for example, face stringent compliance requirements that necessitate comprehensive logging and verification systems. A major U.S. bank recently implemented voice authentication that reduced fraud by

Apr 29, 2026Andrej Karpathy – Outsource your thinking, but you can’t outsource your understanding
https://www.youtube.com/watch?v=96jN2OCOfLs Here's what Andrej Karpathy just figured out that everyone else is still dancing around: we're not in an era of "better models." We're in a different era of computing altogether. And the difference between understanding that and not understanding it is the difference between being a vibe coder and being an agentic engineer. Last October, Karpathy had a realization. AI didn't stop being ChatGPT-adjacent. It fundamentally shifted. Agentic coherent workflows started to actually work. And he's spent the last three months living in side projects, VB coding, exploring what's actually possible. What he found is a framework that explains...

A summary of key takeaways from Andrej Karpathy's conversation with Dwarkesh Patel In a wide-ranging conversation with Dwarkesh Patel, Andrej Karpathy — former head of AI at Tesla, founding member of OpenAI, and creator of some of the most popular AI educational content on the internet — shared his views on where AI is headed, what's still broken, and why he's now pouring his energy into education. Here are the key takeaways. "It's the Decade of Agents, Not the Year of Agents" Karpathy's now-famous quote is a direct pushback on industry hype. Early agents like Claude Code and Codex are...
