Amazon Says It Has Over 10k Employees Working on Alexa, Echo

Amazon has still sold millions of these devices and thus has inordinate amounts of data. When you're talking about training sets that are, say, 1 trillion large vs 10 trillion, does it really make that much of a difference? It's diminishing returns. 10X the data size comes nowhere close to a 10X difference in quality at that scale.

I neither work on Alexa nor on Google Assistant. But based on my experience, going from 99% accuracy to 99.9% would require much more data than 0.9%. Same with adding each subsequent "9".

And the perceived quality difference between 99% accuracy and 99.99% accuracy is much much bigger.

In my experience, like with high availability, each additional 9 requires between double to 10x the resources to achieve.
