What is t - voicing?
striking characteristic of American pronunciation occurs in words like water , better, waiting, 49ers quarterback to non-American and English people it sounds like a /d/ rather
than a /t/ phonetically it is not a plosive
Two different manners of articulation
alveolar tap (e.g. water, better) retroflex flap (e.g. dirty, party)

Occurs: inter-vocalically in a word (pretty , water ) word-finally before a vowel (put it , light up
) foot-internally after the nasal as a nasalized

A tap/flap has a different acoustic quality than a , therefore it is an oversimplification to call it .
What are the differences in quality? analysis in praat Used words:

Initial - dinner
release is marked by high intensity of higher formants
fifth formant at 4500-4900 Hz has highest intensity
the lower formants are comparatively weak

Voiced tap - pottery
in all frequency ranges relatively low intensity
highest intensity in first formant voice bar at ~ 440 HZ
higher formants hardly visible

Voiced tap - simplicity

clearly visible, as intense as 1st formant release
tap quality is similar to quality of initial similar contexts?
