In 2010, it was discovered that whispering is one of the many triggers of ASMR, a tingling sensation caused by listening to soft, relaxing sounds. Social role Īn ASMR video wherein the performer whispers to the camera. However, a sub-dot under phonemically voiced segments is sometimes seen in the literature, as for whispered should. There is no symbol in the IPA for whispered phonation, since it is not used phonemically in any language. More advanced techniques such as neural networks may be used, however, as is done by Amazon Alexa. Because of this, implementing speech recognition for whispered speech is more difficult, as the characteristic spectral range needed to detect syllables and words is not given through the total absence of tone. In whispering, only the voicing segments change, so that the vocal cords alternate between whisper and voicelessness (though the acoustic difference between the two states is minimal). In normal speech, the vocal cords alternate between states of voice and voicelessness. Supralaryngeal articulation remains the same as in normal speech. Whispering is an unvoiced mode of phonation in which the vocal cords are abducted so that they do not vibrate air passes between the arytenoid cartilages to create audible turbulence during speech.
