“Could you confirm your name, please?”

“Could you confirm the purpose of your call?”

2/ Figures

Numbers can be misunderstood. Example: thirty / thirteen. Don't hesitate to ask the person you are speaking to to repeat or even give an order of magnitude.

3/ Spelled words

Similarly, spelled names are often misunderstood. Here are some examples of the most common confusions when an English speaker spells out letters on the telephone.

The vowels A / E / I

  • A → /eɪ/ → “é”
  • E → /iː/ → “i”
  • I → /aɪ/ → “aï”

When an English speaker says “e”, Some people can understand and write down «i».

Another common confusion : G / J

  • G → /dʒiː/ → “dji”
  • J → /dʒeɪ/ → “djeï”

Useful expressions to clarify :

  • “Did you say A as in Alpha?”
  • “Could you spell that using a word for each letter?”
