Sometimes I hear, sometimes not, depends on how much fantasy I unleash or if I use voice "recordings" to prevent me from making mistakes in writing a text in a foreign language. And I practiced fast reading as a kid (e.g. 1 page in 2-5s), and that was for sure without any distinctive voice. Now this helps me to spot a line in code I need to change extremely quickly ;-)
It's like with thinking - when you are a kid, you think in some proto-thoughts that aren't really based on a language (something like assembly language of mind) and the older you are and more languages you know, you tend to think in languages instead, except when you are in a creative flow when things just happen automagically.
