Connected Speech & Natural Conversational Flow
When followed by a vowel, insert a subtle glide (/w/ or /j/) to connect into the subsequent word without an abrupt glottal stop.
In natural sentences, avoid over-stressing "four stroke" unless it conveys the core contrast or focal point of your message.
