Common Pronunciation Traps & Learner Mistakes

How Native Speakers Say It: Sustain vowel clarity without rushing into the trailing consonant. Elevate pitch slightly when "ca2" carries the primary contrast or new information in a sentence.
Connected Speech & Natural Conversational Flow
When "ca2" is followed by a word starting with a vowel, glide the final consonant into the opening vowel (e.g. "ca2 is" sounds like "ca2-iz").
In natural sentences, avoid over-stressing "ca2" unless it conveys the core contrast or focal point of your message.
