The <span class="pho">t</span> sound may be the most complex in American English consonant pronunciations — and certainly one of the most frequently used. In American English, at least four variations, or *allophones*, of <span class="pho">t</span> exist:
> * 正常音 <span class="pho">t</span> - 只有 <span class="pho">t</span> 处于重音音节开头的时候才被正常读出，比如，*take* <span class="pho alt">teɪk</span><span class="speak-word-inline" data-audio-us-male="/audios/us/take-us-male.mp3" data-audio-us-female="/audios/us/take-us-female.mp3"></span>；
> * Standard <span class="pho">t</span> - This is the typical pronunciation, only used when <span class="pho">t</span> begins a stressed syllable, as in *take* <span class="pho alt">teɪk</span><span class="speak-word-inline" data-audio-us-male="/audios/us/take-us-male.mp3" data-audio-us-female="/audios/us/take-us-female.mp3"></span>.
> * 正常音 <span class="pho">t</span> - 通常是 <span class="pho">t</span> 处于重音音节开头的时候才会被正常读出，比如，*take* <span class="pho alt">teɪk</span><span class="speak-word-inline" data-audio-us-male="/audios/us/take-us-male.mp3" data-audio-us-female="/audios/us/take-us-female.mp3"></span>；
> * Standard <span class="pho">t</span> - This is the typical pronunciation, when <span class="pho">t</span> begins a stressed syllable, as in *take* <span class="pho alt">teɪk</span><span class="speak-word-inline" data-audio-us-male="/audios/us/take-us-male.mp3" data-audio-us-female="/audios/us/take-us-female.mp3"></span>.
> * 弹舌音 <span class="pho">t̬</span> - 夹在两个元音中间的 <span class="pho">t</span> 会变成接近 <span class="pho">d</span> 的弹舌音 <span class="pho">t̬</span>，比如，*water* <span class="pho alt">ˈwɑːt̬ɚ</span><span class="speak-word-inline" data-audio-us-male="/audios/us/water-us-male.mp3" data-audio-us-female="/audios/us/water-us-female.mp3"></span>；
> * Flaping <span class="pho">t̬</span>: When <span class="pho">t</span> is situated between two vowels, it tends to be flaping <span class="pho">t̬</span>, sounding like <span class="pho">d</span>, as in water <span class="pho alt">ˈwɑːt̬ɚ</span><span class="speak-word-inline" data-audio-us-male="/audios/us/water-us-male.mp3" data-audio-us-female="/audios/us/water-us-female.mp3"></span>.
> * 喉塞音 <span class="pho">ʔ</span> - <span class="pho">m/n/l</span> 之前的 <span class="pho">t</span> 有可能变成喉塞音 <span class="pho">ʔ</span>，比如，*utmost* <span class="pho alt">ˈəʔˌmoʊst</span><span class="speak-word-inline" data-audio-us-male="/audios/us/utmost-us-male.mp3" data-audio-us-female="/audios/us/utmost-us-female.mp3"></span>, *fitness* <span class="pho alt">ˈfɪʔnəs</span><span class="speak-word-inline" data-audio-us-male="/audios/us/fitness-us-male.mp3" data-audio-us-female="/audios/us/fitness-us-female.mp3"></span>, *witness* <span class="pho alt">ˈwɪʔnəs</span><span class="speak-word-inline" data-audio-us-male="/audios/us/witness-us-male.mp3" data-audio-us-female="/audios/us/witness-us-female.mp3"></span>, 或 *fruitless* <span class="pho alt">ˈfruːtləs</span><span class="speak-word-inline" data-audio-us-male="/audios/us/fruitless-us-male.mp3" data-audio-us-female="/audios/us/fruitless-us-female.mp3"></span>。如果你不知道喉塞音是什么样的，听听 *Uh-Oh!* <span class="speak-word-inline" data-audio-us-female="/audios/us/Uh-Oh.mp3"></span>—— <span class="pho alt">ʌʔoʊ</span>……
