I know that 'i.e.' is an abbreviation of 'that is'. But, my question is about pronouncing it perhaps,
- in normal speech,
- reading from a piece of text containing the abbreviation, etc.
In the US, most people (I have interacted with) pronounce 'i.e.' by uttering the two letters 'I' and 'E'. So, it would sound like 'eye ee'.
However, I have heard very few Americans say 'that is' instead of 'eye ee'. I have observed this when I saw them read a piece of text like a news article. It's like they replaced 'i.e.' with 'that is' in the text and then, read it.
How common is the latter pronunciation in the US? How is 'i.e.' said in the rest of the English-speaking world?
