Formant Analysis Using Wideband Spectographic Representation

By Brandon Henman

Topic Background

Audio Files

Custom-recorded, 16kHz sampling rate

Me saying "a" :Media:Vowels_voiced_a.wav ("ay")

Me saying "e" :Media:Vowels_voiced_e.wav ("ee")

Me saying "i" :Media:Vowels_voiced_i.wav ("eye")

Me saying "o" :Media:Vowels_voiced_o.wav ("oh")

Me saying "u" :Media:Vowels_voiced_u.wav ("yoo")


Methodology

Time Domain Representation of Signals:SpeechSignals.png

Matlab Code

Spectogram Results
