Voice agents are more than speech in, speech out. Luke Farrell has recently talked to @kraenhansen.dk about perceived latency, turn-taking, interruption handling, and the tradeoff between speed and expressiveness. Watch their conversation ⬇️ clstk.com/4v3o7iK

How Voice Agents Handle Latency, Turn-Taking, and Safety With Kræn Hansen

Kræn Hansen (ElevenLabs) talks voice-agent UX, from turn-taking and safety to layered SDK design for React and React Native.

I've always enjoyed pair programming as a way to spend time with my colleagues and collaborators, while building something useful. As assisted software engineering is moving up the chain of abstraction, I'm wondering if "Pair Planning" is going to be a thing?

11k people are using the ElevenLabs MCP server in Claude. It connects to your ElevenLabs account and lets you generate speech, sound effects, and music directly in Claude. All the friction of generating audio with ElevenLabs is gone.

If your data and language model live on the device, why should the app need a network round trip to interact with them? @psyche.social & @kraenhansen.dk talk about: 🔹 local-first software 🔹 mobile security practices like certificate pinning 🔹 voice AI and real engineering stories Listen now 🎧

I'm wondering if we shouldn't start formalizing a move of the review process "up the chain"? Reviewing code is largely decoupled from the plan which generated it and incorporating architectural feedback on a PR largely generated feels more like passing messages between prisoners 😬

Tune in to the latest episode of React Universe on Air where @psyche.social‬ and I have a jolly conversation about a mixed bag of topics dear to my heart 💙 #local-first, #ai powered toys for my kids, #hacking my bank, #stoicism and #parenting to name a few 😂

@elevenlabs.io just announced raising $500M at an $11B valuation to transform how people interact with technology 🎉 Valuation doubling since I signed my contract ... coincidence? I think not 🤔 This place has so much talent and so much potential and I'm really happy to be a part of the journey!

Captive thumbnail signaling the $11.000.000.000 valuation.
