Describe the bug

JAWS default settings will narrate punctuations.

So, when JAWS narrate bot message, the "Bot said: Hello, World!" will be narrated as "bot said colon hello world".

It is better to remove the colon in en-US.json.

Steps to reproduce

1. Run JAWS
2. Type "echo Hello, World!" to the MockBot

Expected behavior

It should say "bot said hello world". Instead, it said "bot said colon hello world".
