Find out audio files are similar or not

[Deepna Sorathiya]

Hi 

I have two audio files.

I need to find out

1.  audio files are similar or not. 

2. speech is similar or not(exact words are matching)

I figured out whether the same person is speaking or not using Librosa. Not sure about comparing speech with exact same words. Can we use any Librosa class or method to compare speech with exact same words.

Thank you
