Whispered Speech A Presentation by Susanne Filges, Agata Mroczkowska and Annette Radon

Phonation Modes "normal" voice breathy voice ("bedroom voice") creaky voice (dislike) whisper

What does whispering mean in general? sounds "soft" less amplitude no difference in meaning between a whispered and a "normal" sound a speech variant across all languages no special IPA symbol for whispered sounds

How to Find Out the Distinction Method of Analysis two non-words "sha" and "shu", spoken in "normal voice" and whispered mode recorded with cool edit converted into spectrograms by Praat

Sha normal

sha whispered

shu normal

shu whispered

Pulses there are no blue lines in whispered voice, only in "normal" speech

Intensity The yellow line shows that the intensity in normal speech is higher than in whispered speech

Spectrogram same relation between dark and light shades in normal and whispered speech

Formants more "red dots" in normal speech formants at a lower frequency only in normal speech more acoustic energy in normal speech

Pitch total absence of pitch in whispered speech no fundamental frequency in whispered speech

Major Difference missing of pitch means no vibration of the vocal folds

An easier way to get this result would have been touching your throat while whispering!
