The quality of the voice we create is very dependent on your natural speech quality. If you have a progressive condition, you should record before your voice is affected. Nonetheless, if your voice is just a little breathy or hoarse, it will probably still be possible to make a useful synthetic voice. The more trouble you have speaking, the more difficult it will be for you to record all the sentences that are needed, and the more difficult it will be for our software to find all the speech sounds it needs to make a useful synthetic voice. If you cannot repeat short sentences without pausing or slurring, you may find the recording process to be too taxing for you and the resulting synthetic voice may not be very usable.
I am starting to have trouble speaking; can I still make a personal voice?
