Inside Alexa Plus: Amazon's Blake Nussey on Voice AI, Far Field Tech and Building for Australia

Blake Nussey leads at Amazon on Alexa, and he joins Georgie for a deep dive into Alexa Plus, now live in Australia. They cover the shift from rigid voice commands to a true personal assistant powered by over 70 models, and why Amazon built a model agnostic architecture to trade off speed against reasoning depth.

The conversation gets personal fast: a customer who broke her leg and called for help through Alexa, Blake's Alexa run wind down routine, and why "don't lead the witness" has become his and Georgie's go to line for settling arguments with a neutral AI referee. They dig into what it actually took to make Alexa understand Australian English (avo, servo and all), the far field listening tech that lets Alexa hear you across a noisy room, and how privacy and trust are engineered in, down to a hardware mute button.

They also talk accessibility (Alexa's role for vision impaired and elderly users), kids and voice AI, and Blake's prediction for when voice hits 50% of how we interact with tech. Plus a rapid fire round covering Tesla FSD, Brazilian Jiu-Jitsu, flat whites, and Jimmethy the raccoon.
