SPEECH SOUNDS

SPEECH SOUNDS

1. SPEECH PRODUCTION MECHANISM

   • ORGAN GROUPS THAT PRODUCE DIFFERENT SPEECH SOUNDS
   • TRACHEA
     • WINDPIPE
   • EPIGLOTTIS
     • DEFLECTS FOOD FROMENTERING THE TRACHEA
     • Small mass
   • VOCAL FOLDS
     • TWO MASSES OF FLESH STRETCH BETWEEN THE FRONT AND BACK OF THE LARYNX
     • Second protection mechanism
     • False vocal folds Third protection
     • THREE PRIMARY STATES
       • BREATING
       • UNVOICED
       • VOICED
     • Attached to the two
       • ARTENOID CARTILGES
         • CONTROL THE SIZE OF GLOTTIS AND MUSCLES WITHIN THE FOLDS
         • LOCATED AT FRONT OF THE ADAM'S APPLE
   • GLOTTIS
     • SLIT-LIKE ORIFICE (SPACE) BETWEEN THE TWO FOLDS
   • SPEECH ORGANS
     • VOCAL TRACT
       • Oral, nasal and pharynx cavities
       • GIVING THE MODULATED AIRFLOW ITS "COLOR"
       • DIFFERENT PARTS IN IT CALLED ARTICULATORS
         • Study: PHONETICS
         • PARYNX
           • DIVIDED IN TWO
             • ONE PART BEINGTHE BACK OF ORAL CAVITY
             • OTHER PART BEING THE BEGINNING OF THE WAY THROUGH THA NASAL CAVITY
         • SOFT PALATE (VELUM)
           • IT'S RAISIN WHEN WE PRODUCE SOUNDS
           • CAN BE TOUCHED BY THE TONGE
           • When the TONGE is in contact with the lowerside of SOFT PALATE
             • VELAR CONSONANTS
         • HARD PALATE
           • "ROOF OF THE MOUTH)
           • When the TONGE is closed to the HARD PALATE
             • PALATAL CONSONANTS
         • ALVEOLAR RIDGE
           • BETWEEN THE TOP OF THE TEETH AND THE HARD PALATE
           • When TONGE touch here
             • VELAR CONSONANTS
         • THE TONGE
           • CAN BE MOVED INTO MANY DIFFERENT PLACES AND SHAPES
           • IS DIVIDED
             • TIP
             • BLADE
             • FRONT
             • BACK
             • ROOT
         • THE TEETH
           • BEHIND THE LIPS
           • When MOUTH is in contact whit the UPPER SIDE OF THE TEETH
             • DENTAL
         • LIPS
           • Pressed together or in contact each other
             • BILABIAL
           • When they are in contactwhit the teeth
             • LABIODENTAL
     • LARYNX
       • Control of
       • MODULATES AIRFLOW AND PROVIDES PERIODIC PUFF-LIKE OR A NOISY AIRFLOW SOURCE
       • System of cartilages muscles and ligaments
     • LUNGS
       • POWER SUPPLY PROVIDE AIRFLOW INHALATION AND EXHALATION

2. PURELY PHONETIC FEATURES

   • DESCRIPTION OF SPEECH SOUNDS
     • SUPRASEGMENTAL FEATURE
       • LOUDNESS
         • Amplitud Vibration
           • greater = louder
           • VOCAL FOLDS
             • Frequency Vibration
               • faster = higher
       • PITCH
     • DURATION
       • Absolute time to articulate a sound
       • Phonetic
     • LENGHT
       • Phonology
       • Relative time to articulate a sound
     • AIR-STREAM MECHANISM
       • Expulsion of the air
         • Egressive pulmonic
         • Egressive glottalic
         • Ingressive glottalic
         • Ingressive velaric
     • TONE OF VOICE
       • Timbre "Color" of voice
         • Paralinguistic feature
