I have never used voice acting before but when I tried using some audio files to test it out it was semi-confusing. I see that there is a speech folder under audio in AGS and a speech folder in the project folder. I have also experimented with the auto number audio feature. What I want to know is what do I do once I have all the audio files for different lines and all dialog lines are numbered?
Did you read the manual entry on voice speech?
It's in
Other Features -> Music and sound -> Voice speech
You basically name the files according to the number and character and put them inside your game's speech folder (outside the editor). You should select "rebuild file(s)" before testing it, but that's pretty much it.
Thanks a lot! In AGS it says to search the manual for voice speech, but somehow this page in the manual didn't come up :/
