| Term | Definition |
| Name 5 uses for phonetics and phonology | speech therapy, medical research (speech pathology, neurolinguistics, physiology), acoustics & signal processing, speech technology (speech synthesis, automatic speech recognition) |
| Define Phonetics | the study of human speech sounds |
| Phone | unit of single identified speech sound |
| articulatory phonetics | speech organs and their use |
| acoustic phonetics | sound waves |
| auditory phonetics | hearing and processing in the brain |
| define phonology | the study of speech sounds in a language system |
| phoneme | unit of speech that distinguishes meaning in a language system |
| phonetic differences | phonologically irrelevant, if they have no effect on meaning |
| phoneme in the speaker's mind | abstract representation, until it is realized physically by one or more allophones |
| allophones have: | sensitivity to phonological context, variation in production |
| minimal pair | difference in phoneme meaning due to one different segment: bit-beat, pain-gain, hit-hip |
| name 2 minimal pairs | chair-hair, floor-door |
| phonological contrast means: | there is a language relevant phoneme |
| phones that don't contrast | allophones of the same phoneme |
| distribution of allophones | explain comlementary vs. free variation |
| complimentary distribution | allophones occur according to certain phonetic rules, such as (p(h) always occurs at the syllable onset and when followed by a vowel, and (p) occurs everywhere else |
| free variation | allophones that can occur everywhere without having their meaning changed, a matter of personal preference |
| biunique | you can always tell which phonemes and allophones belong to each other from the phonological environment |
