How we Communicate Voiceless Breathy or murmur Whisper Voiced Creaky

So what is Sound ... and then by articulation, responsible for further shaping the eventual speech sound this airstream is modified at later stages. First by a process that is responsible for voice/voicelessness called phonation, ...

Vocal Tract and Function

Vocal tract and function Lungs are source of air stream essential to speech Diaphragm pushes the air through the windpipe and into the mouth the muscles of the rib cage do the same The vocal cords housed in the larynx or voice box vibrates so provide our voice The oral cavity contains the parts of the mouth that enable us to speak

Types of phonation Glottis is opened Don’t vibrate Whisper phonation Glottis is opened Don’t vibrate Narrow vocal fold opening Tensed and rigid Unvoiced

Voiceless phonation Minimal obstruction Air passes directly to the glottis Vocal folds opened Noiseless flow

Voiced phonation Air causes to vibrate Full opening and closing of vocal folds Vocal folds are close together Obstruction

Creaky phonation Low frequency irregular air burst Only a small portion of vocal folds open and close Vocal folds are lax Tightly approximated

Breathy phonation Folds are tensed Not fully approximated Complete closure doesn’t occur Noise and air brust Vocal folds partly opened
