A family of Microsoft word processing software products for creating web, email, and print documents.
Thanks @Rohn007 for pointing this out - I have just e-mailed Emily Tran to let her know. She is the person from Microsoft working to fix this.
When we were last in contact she hadn't been able to see the 'hello' problem in action. This might be why.
I think most of us would like to continue using the dictate function - it just needs a bit of perseverance to get there, and collaboration with Microsoft to help them.
Onwards and upwards!
A fix has been deployed to 100% of Dictation users - please let us know if you still see the issue.
