Asl phonology, classes of speech sounds, and feature specifications anthony verzosa

  1. 1. WESTERN MINDANAO STATE UNIVERSITY COLLEGE OF LIBERAL ARTS English Phonology and Art of Speaking ESL 225 Anthony Diaz Verzosa DISCUSSANT

  3. 3. American Sign Language (ASL) Phonology Sign languages such as the American Sign Language (ASL) are characterized by phonological processes analogous to, yet dissimilar from those of oral languages. The phonology of sign language can be further understood in broad categories called parameters. Parameters are distinguishing features or noticeable characteristics used for creating signs with meaning in ASL.

  5. 5. The Parameters in ASL Phonology 1. Location/Placement 2. Movement (Repetition/Direction) 3. Palm Orientation 4. Handshape 5. Facial Expression
  6. 6. Location This refers to the physical parameters of bodily locations where the signs are produced Examples are the signs for “mother” and “father”/ signs for “apple” and “onion”
  7. 7. Movement This refers to the changing of the location of the hand within the set of physical parameters during sign production. Examples are the signs “school” in comparison to “paper”.
  8. 8. Movement Repetition This is where we get what we call in sign language “noun-verb pairs”. Examples are the signs for “sit” and “chair” / signs for “fly” and “airplane” Direction This refers to the course of movements within a sign. Examples are the signs for “paper” and the verb “to clean”.
  9. 9. Palm Orientation This refers to the direction in which the hand is turned to produce a sign. Palm Orientation is the direction of your palm which may include palm up, palm down, palm right, palm left, palm outward, and palm inward.
  10. 10. • Examples: “children” ------ palm down “things” -------palm up “balance’ ----- palms down and simultaneously moving from top to bottom “maybe”------palms down and simultaneously moving from top to bottom
  11. 11. Handshape Handshape refers physically to the shape of the hand producing the sign. You can describe the shape very specifically, like all 4 fingers are straight and close together and the thumb is across the hand or you can describe it by comparing the shape to a known ASL shape.
  12. 12. • Examples are the signs for “mother” and the verb “to imbibe” / signs for “school” and “impossible”
  13. 13. Facial Expression A facial expression is one or more emotions or potions of the muscles beneath the skin of the face. The movements convey emotional state of an individual two observers. Facial expressions are a form of none verbal communication. These are non-manual signals. For example, if you sign the word “quiet” and add an exaggerated or intense facial expression, you are telling the audience to be “very quiet”.
  14. 14. CONCLUSION The phonology in American Sign Language can be broken down to section and segments similar to spoken language. The phonemes in sign language are categorically represented through a feature called parameters. The individual parameters in sign language bear no meaning but blending and changing one parameter with another parameter can change the meaning of one morpheme or a word or form a new one; a principle that is closely similar to that presented in spoken language.
  15. 15. Natural Classes of Speech Sounds In phonology, a natural class is a set of phonemes in a language that share certain distinctive features. A natural class is a group of sounds described by a small number of distinctive features All members of a natural class have the same effect on other sounds that occur in their environment. Natural classes can be defined by (+) and (–) feature values
  16. 16. For a group of sounds to constitute a natural class, they must all share one or more features and there should be no other sounds in the language that have this feature or combination of features
  17. 17. Example: the phonemes [p, t, k,] can be grouped together as a natural class by showing the binary distribution of the features. voiceless stops in the English language
  18. 18. If one feature is altered, the natural class is changed. voiced stops in Standard English
  19. 19. The third table shows that when one more feature is altered, yet a different natural class is yielded. Now that the feature [continuant] has been altered from [-] to [+], we must add all the sounds in English that fit this description. Voiced Fricatives
  20. 20. • Often the case is that, the fewer features used to describe a natural class, the larger the class. • However, by adding features, we reduce the possible candidates for a natural class.
  21. 21. [-syll] = [p, b, t, d, k, g, ʔ, f, v, s, z, ʃ, ʒ, tʃ, dʒ, x, ɣ, ɢ, h, ɹ, l, n, m, ŋ, j] [-syll, +voice] = [b, d, g, v, z, ʒ, dʒ, ɣ, ɢ] [-syll, +voice +continuant] = [v, z, ʒ, ɣ]
  22. 22. Feature Specification for American English Consonants and Vowels Through the following charts, one may be able to easily identify the members of each class of phonemes by selecting all the segments marked + or – for a single feature.
