What is the sound corresponding to the letter quot;tquot; in this word?

1. What is the sound corresponding to the letter "t" in this word?

a. This sound is an alveolar flap (or tap) and the IPA character is [ɾ], although sometimes the character [d] is used because the phoneme /d/ is pronounced the same way in words like ladder.

b. This sound is a voiceless alveolar stop and the IPA character is [t], even though the vocal cords are vibrating, as they are with the sound [d].

c. This sound is a voiced aspirated alveolar stop, for which the IPA character is [ɗ].

d. This sound is an unreleased voiceless alveolar stop and the IPA character is [t̪]. There is no voicing.

2. The letter "t" can correspond to several different sounds, as illustrated by the pronunciation of the phrase "at her," as in the ordinary casual-speech pronunciation in American English of "I was looking at her." This is the same sound that is found in water. In both cases, and in all cases where this sound is encountered, it immediately precedes an unstressed syllable (see also: butter, batter, data, gotta, petal, and countless other words). The sounds that are characteristically represented by the letter "t" (either double or single) also include an aspirated voiceless stop, which occurs as the first sound of a stressed syllable as in talk and attain, as well as an unreleased alveolar stop or glottal stop just before a syllabic alveolar nasal, as in button, kitten, Latin and countless other words.

In the English writing system these different sounds are all typically represented by the letter "t" rather than by other letters that might better signal the differences between them because they [ Select ] [a."get represented by different letters only in languages with syllabaries", b."don't all occur in British English", c."are all allophones of the phoneme/t/"] and alphabetic writing systems [ Select ]  [a. "are designed to have letters represent phonemes", b. "don't have enough characters available to represent all the sounds", c. "are only used for languages that don't have lots of allophones for most phonemes"]            .
