Common Pronunciation Traps & Learner Mistakes
The Trap: Pronouncing a hard, aspirated [tʰ] in casual conversation can sound overly formal in North America.
How Native Speakers Say It: In American English, a single "t" between vowels quickly taps against the alveolar ridge like a soft "d" ([ɾ]). In British English, maintain a crisp aspirated [tʰ].
Connected Speech & Natural Conversational Flow
When followed by a vowel, insert a subtle glide (/w/ or /j/) to connect into the subsequent word without an abrupt glottal stop.
Maintain the stress-timed rhythm of English: compress unstressed syllables rapidly so the beat of "infinitive" aligns naturally with adjacent words.
