Shift+F5 - Speak selected text to file - plays slow

[koshka]

Hi,

I'm using TextAloud 3.0.111. Using voice IVONA Salli22.

I highlighted some text, selected - Speak - Speak selected text to file ( Shift+F5 )
which created an mp3 file - Welcome to TextAloud 3.mp3

When I play this file back using say Audacity or VLC, the speech is slightly than if
I play within TextAloud using the button "Selected Text" !!!!!!!

The small highlighted section played within TextAloud takes about 9.5 seconds
but the mp3 file takes about 13 seconds.

Any suggestions.
Thanks
