The correct spelling of the phrase "one the control" is actually "on the control." The sound represented by the "e" in "one" is different from the sound in "on." The phonetic transcription for "one" is /wʌn/ while the transcription for "on" is /ɒn/. The difference lies in the vowel sound, with "one" pronounced with a shorter "u" sound and "on" pronounced with a longer "o" sound. It is important to pay attention to phonetic sounds when spelling words to ensure accuracy.
