Unformatted text preview: Vowels vs Consonants Once we have identified all human speech sounds, we want to characterize them in an unambiguous way. Basic classification: Vowels, Consonants (& Glides) Vowels vs Consonants Once we have identified all human speech sounds, we want to characterize them in an unambiguous way. Basic classification: Vowels, Consonants (& Glides)- Vowels : produced without a real obstruction of the air stream- Consonants : produced with an obstruction of the air stream Vowels vs Consonants Once we have identified all human speech sounds, we want to characterize them in an unambiguous way. Basic classification: Vowels, Consonants (& Glides)- Vowels : produced without a real obstruction of the air stream highly sonorous- Consonants : produced with an obstruction of the air stream not as sonorous as consonants Vowels vs Consonants Once we have identified all human speech sounds, we want to characterize them in an unambiguous way. Basic classification: Vowels, Consonants (& Glides)- Vowels : produced without a real obstruction of the air stream highly sonorous represent syllabic nuclei- Consonants : produced with an obstruction of the air stream not as sonorous as consonants do not pattern as syllabic nuclei (with a few exceptions) Vowels vs Consonants Once we have identified all human speech sounds, we want to characterize them in an unambiguous way. Basic classification: Vowels, Consonants (& Glides)- Vowels : produced without a real obstruction of the air stream highly sonorous represent syllabic nuclei Glides vowel-like in articulation distributed like consonants- Consonants : produced with a obstruction of the air stream not as sonorous as consonants do not pattern as syllabic nuclei (with a few exceptions) Consonants Once we have identified all human speech sounds, we want to characterize them in an unambiguous way. Speech sounds can be described in terms of how they are articulated. These ARTICULATORY DESCRIPTIONS should be completely unambiguous. Therefore, several criteria are used in them. 1) Voicing (vibration of the vocal folds) (a) Vocal folds far apart voiceless speech sounds (b) Vocal folds close together air stream causes vibration voiced speech sounds Consonants 2) Place of articulation (where in the vocal tract the articulators make contact or become close together) Articulator-tongue-lips:-teeth: -alveolar ridge: -palate:-velum:-glottis: Consonants 2) Place of articulation (where in the vocal tract the articulators make contact or become close together) Articulator-tongue-lips: bilabial / labiodental-teeth: -alveolar ridge: -palate:-velum:-glottis: Consonants 2) Place of articulation (where in the vocal tract the articulators make contact or become close together) Articulator-tongue-lips: bilabial / labiodental-teeth: labiodental / interdental-alveolar ridge: -palate:-velum:-glottis: Consonants 2) Place of articulation (where in the vocal tract the articulators make contact or become close together) Articulator-tongue-lips:...
