Having trouble with speech pronunciation after connecting my iPhone with my BrailleNote

I connected my BrailleNote via bleutooth to my phone, but after disconnecting the BrailleNote, I find that now my phone is not pronouncing some words and numbers correctly. For example: it's messing up the apostrophe pronunciation. Instead of saying the word "isn't" it says something like "isn 'T". Also with numbers, it says battery level ninety instead of saying ninety percent like it usually does. Does anyone know what I might have done to cause this? If I didn't explain it clearly enough, I'll try to do so again. Thank you for any help.
