I think you can also say: parler à haute voix
yes, that is correct
We say Parler a voix hautE et non a voix haut!
Why is the t in tout silent here? I would have expected it to be pronounced since it's followed by haut
The "h" in "haut" is aspirated - there is no elision.
Good to know, thanks
That means "heavily". Not applicable.
Elle parle à haute voix is marked as incorrect. Argggh!
That exact sentence is now accepted. 13Nov14
