Ken would like to use voice to text without using the internet. Leo says that there are plenty of programs that can do it, but Leo likes Dragon Naturally Speaking. He could even use it on the Winbook TW802 tablet, which is $139 on Amazon right now.
When he upgrades to Windows 10, Cortana will do dictation, but Leo doesn't know if she'll do it online. Dragon can do this offline no problem, though.
