Syllable Architecture & Stress Distribution
FAST
Tense long vowel with sustained acoustic resonance.

Reduced vowel sound, relaxed jaw, and minimal vocal effort.
Primary emphasis falls on the first syllable ("FAST"). Raise your pitch and sustain the vowel length on this syllable while relaxing the surrounding syllables.
Common Pronunciation Traps & Learner Mistakes
The Trap: Avoid pronouncing every vowel with full acoustic weight. Non-native speakers often over-enunciate unstressed vowels.
How Native Speakers Say It: Only give full vowel clarity to the primary stressed syllable. Relax all unstressed vowels into a neutral, low-energy schwa (⁄ə⁄).
Connected Speech & Natural Conversational Flow
When "fastball" is followed by a word starting with a vowel, glide the final consonant into the opening vowel (e.g. "fastball is" sounds like "fastball-iz").
In natural sentences, avoid over-stressing "fastball" unless it conveys the core contrast or focal point of your message.
