Building Voice Agents with Luke Harries of ElevenLabs

Get ready, AI Tinkerers.

We’re going deep into voice agents, personal workflows, and AI-first product building with Luke Harris, Head of Growth at ElevenLabs — and a true hands-on builder.

In this episode of One-Shot, Luke unpacks how he built the most popular WhatsApp MTP server, how ElevenLabs is redefining voice AI, and why smart shortcuts (literally) matter more than big architectures.

“You don’t need a 100-person team to build something great. You need a real problem and a fast feedback loop.” — Luke Harris

We break down:

1. How Luke built the #1 WhatsApp MTP server using Apple Shortcuts
2. Why consumer AI still has massive white space
3. How ElevenLabs’ Scribe delivers near-human transcription and diarization
4. Designing low-latency, emotionally expressive voice agents
5. Why personal projects open more doors than strategy decks
6. Growth opportunities in education, sales intelligence, and AI-first product development

Three takeaways you’ll use immediately:

1. Voice Is Underrated Infrastructure
Speech is the original interface. Luke shows how ElevenLabs is productizing that interface with developer-friendly APIs and real performance.

2. Automate Where It Hurts
Whether it’s an iPhone shortcut or a backend script, build where the friction is personal — that’s where great agents start.

3. Start Scrappy, Scale Smart
Luke didn’t wait for approval. He built projects that solved his own problems — and those became the seeds of viral growth.

“If I can shortcut a task that used to take 10 minutes to 30 seconds, I ship it. That’s the game.”
— Luke Harris

This one’s a must-watch if you care about voice, speed, and the future of human-AI interaction.
