The word "ensuring" can be dissected for pronunciation with the International Phonetic Alphabet (IPA) transcriptions for both British and American English as follows:

• American Pronunciation: /ɛnˈʃʊrɪŋ/
  • Begins with the /ɛn/ sound, where the mouth is slightly open, and the tongue is near the front of the mouth but not touching the roof.
  • Followed by the /ˈʃʊr/ part, with the /ʃ/ sound similar to the 'sh' in "shoe". The /ʊr/ is pronounced with a rounded, pushed-forward lip position and a voiced quality.
  • Ends with the /ɪŋ/ sound, a combination of a short, relaxed 'i' as in 'sit', and the 'ng' sound made by pressing the back of your tongue against the soft palate.
• British Pronunciation: /ɪnˈʃʊərɪŋ/
  • The beginning /ɪn/ sound is more closed than in the American version, with the tongue closer to the roof of the mouth.
  • The /ˈʃʊər/ part is similar, with the /ʃ/ sound for 'sh' and a slightly longer /ʊər/ sound, lacking the 'r' sound pronounced at the end.
  • Concludes with the /ɪŋ/ sound, identical to the American pronunciation.
