Speech to text - Cloud service only?

I'm glad to see those with early access to Speech-to-text enjoying the new feature. I signed up, but I figure it will still be awhile before my request is reviewed.

My question for those who have it — and Adobe devs, if you're listening — is, will the Speech-to-text feature be available on a computer without internet access, or is this a Cloud service?

My job requires me to work in a non-networked environment. So, after my computer gets updated by an admin by connecting to the internet to get the lastest Cloud updates, control of my workstation is given back to me without any internet access.

I desperately need a Speech-to-text solution that does not require the internet, so I'm hoping someone can kindly shed some light on this. Thanks in advance.
