How can I save Consecutive Sounds From an Audio Recording into Individual Variables or Array?

Good day I have to analyze vowels and consonants from about 100 different .wav recordings of different people speaking, and compare each vowel and consonant from the first .wav file to the second etc. I have a plan to isolate each sound (where the amplitude of the file is below 0.1, there is no speaking, only noise) whilst filtering out the silences, and place each sound ("a" then "e" respectively etc.) into its own variable labelled a; e; i etc. in order to compare the vowels and consonants individually to the other recordings. I have begun writing if loops but this seems to not work at all, since I have 720000 data points for each file. Please can you help me work out how to do this without taking five hours for each file, for a total of 5*100 hours? I am hoping there is a known function or algorithm which sorts audio sounds consecutively into an array or individual varibles. Thank you so much
