Would you integrate the function"Look up in dictionary" and "Start speaking text" together? That would be more useful to a lot of users like me.

This review is for a previous version of the add-on (0.5). 

Hi aquaibm! How about installing another one of my add-on, DictionaryFox too? That is what I use when I want to look up dictionary.
Also, if you want "Summarize" in your context menu too, there is SummaryFox.
