Common Pronunciation Traps & Learner Mistakes

⚠️ Intervocalic Tap / Flap [ɾ] in American English

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

🔗 Consonant-Vowel Linking (Liaison)

When "undecidability" is followed by a word starting with a vowel, glide the final consonant into the opening vowel (e.g. "undecidability is" sounds like "undecidability-iz").

⏱️ Stress-Timed Rhythm

Maintain the stress-timed rhythm of English: compress unstressed syllables rapidly so the beat of "undecidability" aligns naturally with adjacent words.

📐 Morphological Stress Rule (-ity)

Shifts primary stress to the antepenultimate syllable (two syllables back).
