Consonants
American English Sounds/t̬/The /t/ in tap or sat is a voiceless sound. Many Americans, however, use a voiced sound like a quick /d/ for the /t/ in words like latter, party, and little. The t in these words, shown in this dictionary as /t̬/, sounds like the d in ladder, hardy, and middle. This sound usually occurs between vowels (especially before an unstressed vowel), between r and a vowel, or before a syllabic /l/. /t˺/This symbol means that many speakers pronounce a glottal stop in place of or together with /t/. A glottal stop is the sound in the middle of the expression uh oh. For example, in the words button /ˈbʌt˺n/ andfootball /ˈfʊt˺bɔl/ the t does not sound the same as in the word ton /tʌn/; it sounds like a short period of silence. The glottal stop usually occurs before a syllabic /n/ or a consonant that begins the next syllable. /t/ and /d/These symbols mean that these consonants may be either pronounced or left out. For example, the t inrestless /ˈrɛstlɪs/ and the d in grandfather /ˈgrændˌfɑðɚ/ are usually dropped in normal connected speech, even though it is considered more correct in slow, careful speech to pronounce the t and d in these words. /nʃ/Many speakers pronounce the sequence /nʃ/ as /ntʃ/. For example, attention /əˈtɛnʃən/, conscious /ˈkɑnʃəs/ may also be pronounced as /əˈtɛntʃən/, /ˈkɑntʃəs/. Only the pronunciation with /nʃ/ is shown.
