how to say my name

If a linguist would try to say my name, it would be easy for them, they would pronounce it like this [dɛnis]. often, when my name is read off a roster some people tend to pronounce it like [dɛnIs], which is completely wrong, this is a males name (denis). now if i were to show a non-linguist how to pronounce my name, i would tell them to put their tongue on their upper teeth and say "de" like you would for the word den. next, with their tongue in the same place, i would tell them to let out a nasal sound like "nnnn". finally they should say the letter "e" followed by an "ssss" sound. it would also be easy for them to understand how to say my name if they were to put the word "den" and "niece" together.
