word syllable program help

[sauronamaterasu13]

i am working on a program where the user inputs word/s and my program is supposed to spit out the number of syllables the word/s has (ex: input-simplicity output-4) everything seems to work fine except when i enter in something like this, "fluttershy is awesome like that."
ive tried that input without the period but it keeps giving me 10 syllables for some reason when the expected output is 9

so can some1 help me fix that error
