Diphthing production

change in articulatory posture1. tongue posture2. jaw posture3. lip opening, rounding, unrounding

Phonemic Diphthongs

Distinguish meaning but cant be decreased to monothongs ai, au, ??

Non-phonemic Diphthongs

don't distinguish meaning and can be decreased to /e/ and /o/ monothongsei, ou

consonants description

-place of articulation-manner of production-voicing

monothongs

pure vowels having a single sound quality

diphthongs

have a gradually changing articulation results in 2 resonances /or shift

f1 frequency

Depends on size of aperature and pharyngeal cavity volume.Large aperature and small pharyngeal cavities result in high freq. F1

F2

frequency depends on volume of oral cavity, by tongue advancement More front the tongue higher f2

narrow Transcription

exactly what person said [k]

broad transcription

phonemes not related to how person said them/r/ /k/

progressive vs regressive

progressive- sound segment influences a following soundregressive- sound segment influences preceding sound

Assimilation

one speech sound becomes similar/ identical to a neighboring sound segment

Coarticulation

effect neighboring sounds have on eachother

approximates

consonants with wide passage for airflow

obstruents

complete/ narrow constriction between articulator, hindering expiratory system

distinctive features

phonetic symbols that distinguish phonemes

sound classes

manner of production

morpheme

smallest linguistic unit that convey meaning

allophone

speech sound that is a variant of a phoneme

phoneme

smallest linguistc unit that is able to establish meaning

phonological disorder

impaired system of phonemes and phoneme patterns in spoken language

phonology

study of patterns of speech sounds in a language and pronunciation rules

articulation disorder

difficulty in motor production of speech or inability to produce speech sounds

articulation

motor processes involved in planning sequences of gestures that result in speech

Parameters that affect formant frequencies

-Tongue height-tongue anterior posterior-tense or lax-lip rounding-rhotic non-rhotic-nasality
