             Note
             L    :   Lip

             T    :   Teeth

             TR   :   Teeth – ridge
             HP   :   Hard palate
             SP   :   Soft palate

             U    :   Uvula

             P    :   Pharynx
             Bl   :   Blade, Including the tip
                      of tongue

             F    :   Front of the tongue

             B    :   Back of the tongue
             E    :   Epiglottis
             V    :   Vocal cords
             W    :   Windpipe
             FP   :   Food Passage
             L    :   Larynx
             VOCAL ORGANS

   1. Mouth: lips, teeth, teeth-ridge, palate,
    tongue
   2. Respiratory Organs: nose, pharynx,
    larynx, wind-pipe and lungs
     THE ROOF OF THE MOUTH
   The teeth ridge: behind the teeth which is
    convex to the tongue
   The hard palate: the bony part of the roof
    of the mouth behind the teeth ridge, and
    is concave in shape facing the tongue.
   The soft palate: the remaining fleshy part
    of the roof of the mouth behind the hard
    palate, whose extremity is called the uvula
       THE PHARYNX

Is the cavity situated in the throat
   immediately behind the mouth
   THE EPIGLOTTIS

      Is a sort of tongue
situated just above the larynx
                THE TONGUE
   The back: the part which normally lies opposite
    the soft palate
   The front: the part which normally lies opposite
    the hard palate
   The blade (includes the tip or apex): the part
    which normally lies opposite the teeth-ridge
   The central: includes a small part of the front
    and the back of the tongue
   THE VOCAL CORDS

     Two elastic membranes
situated horizontally in the larynx
  which can be made to assume
         various positions
BASED ON THE FUNCTION SPEECH
  ORGANS CAN BE SUBDIVIDED:
   Initiator: used to set the air into motion
    for the production of speech sounds (the
    main initiator is the lungs)
   Phonator: used to produce speech sound
    called ‘voice’ (refers to the vocal cords in
    the larynx)
   Articulator: used to obstruct the out-going
    air in the production of speech sounds
      KINDS OF ARTICULATORS

   Movable: the lips, the tongue, the uvula,
    and the vocal cords
   Unmovable: the teeth, the teeth-ridge, the
    hard palate
              SOME TERMS

   Articulation: the act of moving two
    articulators toward each other for the
    obstruction of the out going air
   Point of articulation or place of
    obstruction: the point where two
    articulators are touching or almost
    touching each other for the obstruction of
    the out-going air
            PROCESS OF SPEECH
               PRODUCTION
   Speech sounds are basically produced by a
    moving air column, either by the in-going air or
    out-going air.
   Sounds produced by the in-going air are called
    ingressive sounds, while sounds produced by the
    out-going air are called egressive sounds
   Speech sounds used by human beings in
    speaking are mostly the latter type, whereas
    ingressive sounds are rarely used in
    communication.
