Common Pronunciation Traps & Learner Mistakes

⚠️ Single-Syllable Vocal Energy & Vowel Articulation

The Trap: Single-syllable words like "km²" carry primary acoustic prominence in isolation, but can be swallowed in rapid connected speech.

How Native Speakers Say It: Sustain vowel clarity without rushing into the trailing consonant. Elevate pitch slightly when "km²" carries the primary contrast or new information in a sentence.

Connected Speech & Natural Conversational Flow

🔗 Consonant-Vowel Linking (Liaison)

When "km²" is followed by a word starting with a vowel, glide the final consonant into the opening vowel (e.g. "km² is" sounds like "km²-iz").

⏱️ Stress-Timed Rhythm

In natural sentences, avoid over-stressing "km²" unless it conveys the core contrast or focal point of your message.
