1. Go to Options  in the toolbar.
2. Go to Language and Speech.
3. Under Languages, tap the voice you are using.
4. Tap Pronunciation of the language of the voice being used. 

Now, you will create a new pronunciation. As an example, we’ll show you how to create a pronunciation exception for “Sacramento.” Right now, the Josh voice pronounces it like “SAY cruh men toe.” Instead, we want the first ‘a’ to sound like the ‘a’ in ‘apple.’

1. First, select the + in the top right corner of Edit Pronunciation. This opens the new pronunciation configuration.
2. In the top Original Text row, type the word’s spelling. Make sure to capitalize it in the same way it will be written in the app. 
3. In Pronunciation, type how you want Proloquo4Text to pronounce the word. Select Speak to preview your pronunciation. You may need to try a few different pronunciations to get it to sound right.
4. For example, if I type “sa cra men to,” the first ‘a’ sounds like "uh." If I try to fix this by typing "sack ra men to," the second 'a' now sounds a bit like the 'a' in "ray." If I try a third time with "sack ruh men to," it sounds correct.

For more control, you can enter special phonetic codes that tell the voice exactly how to pronounce the word. If you want to use these, toggle Uses Phonetics to ON. You must leave a space between every sound’s code. We recommend that only experienced users try this option.

If I wanted to do this for ‘Sacramento,’ here’s what I would type: s {1 k r @ m E2 n t @U
