Considering the audio stream upload & processing & network jitter/lag, the speed at which text results come back is simply incredible. I don't remember the exact timing, but it was a roundtrip of 40-100?ms which is... crazy/magic.
I made a small experiment with this same Chrome text to speech engine which triggered a google image search and showed in near real time image results for the spoken words. The slowest part of that Rube Goldberg was the google images search + loading the images. [1]
I also.... "secretly" believe that very fast speech recognition is one of "the" secrets to building a smarter / better digital voice assistant. It's one of the key components (with a ton of groundbreaking NLP and/or the right regexes) that might allow closing the "strange feeling" you get when talking to the robot... voice... and... it... answers....... not ... exactly when...... you were expecting it.... to.
I'm super mega busy these days but also super mega interested in this. Reach out? :-)
