"I am not getting any sound and the speaker icon is grayed out when I open the Italian phrase book."
This problem is caused by mismatched rights for the sound database file. Luckily, there is an easy solution to this problem!
If you have a program like File Explorer you can find the file
/opt/Qtopia/bdicty/voice/SndItaPhr.pdb and change the permissions, to - read by owner, read by group, read by others.
If you do not have such a program installed, please start the embedded console and write there:
chmod 755 SndItaPhr.pdb
