Brief summary

In alpha versions, grammar errors are spoken when NVDA is configured to report errors using one or more of the available options, i.e. (speech, sounds and/or braille).

Steps to reproduce

2. Type a sentence with grammar errors, and press Enter.
3. Press up arrow to read the invalid sentence.
