Some animals are specially trained to repeat human phrases, others just make sounds that people interpret as speech.
In this video a rooster seems to say "Cristo Viene" (Christ is coming).
Taking the spectrogram of that rooster to analyze the formant position of the vowels I can't find any matches (I was using a formant position UCLA's chart from here ), because the pitch of the animal is obviously different to formant position of human male or females.
Does anybody knows the way to find the formants position at different pitches? (I put the spectrogram of the rooster above)
