comparing two audio frequncies

[na1992]

Hello there

I am working on getting words from a speaker and compare the signals. what are the most comparable quantities in such cases , i tried with amplitude but not much difference. i thought of analyzing each letter freqeuncy but im not sure exactly how?

any insight?

Hi na,

there are a lot of (scientific) papers on speech recognition. Did you read any of them?

Wikipedia explains that topic too…

Did you search for ready-to-use LabVIEW examples? There are examples used to "remotely" control LabVIEW…
