Apple Machine Learning Journal:

In addition to the speaker vectors, we also store on the phone the “Hey Siri” portion of their corresponding utterance waveforms. When improved transforms are deployed via an over-the-air update, each user profile can then be rebuilt using the stored audio.

The most Apple-like way to continuously improve that I can think of. More interesting, though, is this bit later on:

The network is trained using the speech vector as an input and the corresponding 1-hot vector for each speaker as a target.

To date, ‘personalized Hey Siri’ has meant “the system is trained to recognize only one voice.” That quote, though, sounds like they’re working on multiple-user support; which, with the HomePod, they really should be.

I have always been fascinated by the emergent properties of mathematics: simple rules create complex structures. When you get down to it, this is how all of our modern technology works. Variations is based on that concept and was composed for performance through an application written for the iOS® operating system.
At the core of the application are cellular automata based on Conway’s Game of Life (1970), which is a grid where each square is either ‘on’ or ‘off’ and follows a strict set of rules. A square that is off (‘dead’) can become alive (be ‘born’) if it has the right number of living neighbors. A square that is alive can die if it has too few (loneliness) or too many (starvation) living neighbors. The rules are simple, yet they can create astonishingly complex patterns; there is an entire field of mathematics devoted to studying these patterns, Automata Theory.
Variations allows these patterns to play out both visually and aurally. Tap the screen to allow the grid to move through another cycle of living and dying, or just listen to the music created by a single frozen moment. No two people will ever hear the same set of sounds: the starting point for the patterns, as well as their evolution, are uniquely generated every time the Variations application is run.
