today I’ve read an article about google releasing some end-user TPUs for comparably cheap money.
I never worked with TPU’s myself (or TensorFlow, for that matter), but if I recall correctly both DeepSpeech and Mimic II use TensorFlow for their machine learning models. These two systems require a lot of computational power to run at acceptable speed, and this is the main reason that keeps Mycroft from working without the need of cloud servers for TTS and / or STT.
With TPUs available for end users (even with a raspberry pi per USB, see the link above), could this development help to get us closer to a voice assistant that works well without cloud computing? Maybe not even this first generation of end-user TPUs, but some later product? Maybe someone who understands a bit more of the matter could give us some insights here
