  6. Sounds Categorization • Manner of articulation closure made by the articulators and the degree of the obstruction of the air stream by those articulators. • Place of articulation Position of the articulators e-g: tongue, lips etc. • Status of glottis Voicing : vocal cords are vibrating Voiceless: vocal cords do not vibrate

  7. Sound Categorization • A good link to understand manner and place of articulation (only sounds in American English). http://www.uiowa.edu/~acadtech/phonetics/english/frameset.html

  8. Phonology • Language dependent subject • Few phonological rules • Examples: • Other topics might involve • Script to phonemic conversion • Stress analysis • Syllabification • Intonation

  9. Applications • Formants modeling • Consonant identification • Vowel identification • Klatt Synthesizer • Searching in multimedia databases • Encoding and Speech transmission • Speech recognition • Speaker identification
