WT6000 (Nougat) where is voice recognition

I am developing an application using Xamarin on an WT6000 that is now running Nougat.
It seems that all of the Google voice recognition apis are missing…
How do I utilize speech or voice recognition services on this device?

Is there another app/utility/api that CAN be used on this device to enable voice recognition integration?
Specifically, I am looking to do speech to text to my app.

Thanks in advance!

Converting Base64 String to ZPL in Android

There's a of a chance that this question has been asked in a different way but this is the scenario. Using a webview on Android, we are loading a webpage that has a button that sends a base64 string to our android app for print. I need to figure out a way to convert the Base64 to ZPL and send it to a ZQ630 Printer that we are currently using.

The options I'm considering - converting the base64 to PDF (within Android ) then to ZPL for print. ---side note, I'm curios if the ZQ630 can also print the PDF directly.

Any suggestions will be highly appreciated.

The following are the steps I have been following:
