Common Pronunciation Traps & Learner Mistakes
The Trap: Single-syllable words like "b2o3" 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 "b2o3" carries the primary contrast or new information in a sentence.
Connected Speech & Natural Conversational Flow
When "b2o3" is followed by a word starting with a vowel, glide the final consonant into the opening vowel (e.g. "b2o3 is" sounds like "b2o3-iz").
In natural sentences, avoid over-stressing "b2o3" unless it conveys the core contrast or focal point of your message.
