Yes. Unlike most other BlackBerry applications, Vlingo is always ready to listen, no matter what screen you're on. You don't have to click on the Vlingo icon or bring up the Vlingo home screen in order to speak.
You can press the side button and speak from your phone's idle (home) screen, from an email screen, your calendar, or any other screen. Vlingo will interpret what you said and bring up the appropriate screen for you.
If you have Vlingo Plus with Vlingo Everywhere and you speak text while another application's screen is active, you need to know two things:
Your spoken text will be displayed in a Vlingo Everywhere dialog box. When you click Paste, your text will be inserted wherever your cursor was. There are a few exceptions where the BlackBerry doesn't support this. This is a limitation of the BlackBerry platform and not something that Vlingo can control.
If you want to speak a Vlingo command while another application screen is active, speak 'Vlingo' as the first word. For example, "Vlingo call Bob".
