According to AppleInsider, “The original version of macOS 10.14.6 was released July 22.

You can do this while typing, or while dictating. You can set the spoken phrase to precede a dictation command to make sure the command only executes when you want it to.
From one of my favourite sites that gives many useful hints, the author of the site has posted a video explains the process for using dictation.

See MacMost - Dictation Commands for a video tutorial.

I have personally found two resources quite useful. The first is ScreencastsOnline which is operated by Don McAllister and offers a subscription model although some videos are free to watch.
Another that is free and has had many useful videos is MacMost. From the site "MacMost is a free website with video tutorials for Apple Mac, iPhone and iPad users. Visit here daily for new tutorials, sign up for the free weekly newsletter, check out some Mac tips, and ask questions in the forum. New to the Mac? Check out the Beginner’s Guide to the Mac."
Of course if you prefer to have assistance in resolving any issues with your computer or need to solve some requirement with your software or hardware, I am able to assist with personal service at reasonable rates. The initial assessment of your requirements is free, unlike many trades that charge exorbitant fees just to arrive at your door.
The problem relates to rendering certain Indian characters which could cause the device to crash.
Apparently some mischievous people have intentionally inserted these characters to cause problems for those unfortunate to have encountered them.
Its always a good idea to keep devices up-to-date, especially relating to security issues.
