North African pronunciation of English - please help!?

Question

Which English consonants and vowels do people from Morocco and Algeria have difficulties pronouncing.
i.e.,
in the Far East L and R is confused.

I am trying to write a Berber character in a dialogue and am not sure which letters to substitute.

I have taught English as a foreign Language to other nationalities, there are always problems. I have no experience of north africans. This problem works the other way from English speakers not being able to pronounce words in Magrib Arabic.
I say this because Arabic pronounciation is not universal as many may think.

I was able to locate some information from "Teaching English Pronounciation" pub Longman. It was specifics I wanted.
My daughter learnt Arabic in Egypt she noticed big differences between regions and from Classical Arabic.

Answer 1

I am Egyptian and here is my guess:
1-The difference between e and i as in pit and pet. We don't have these two vowels in Arabic.
2- The difference between ball and bowl. Again , we don't have them in Arabic.
3- Some people will have difficulties pronouncing , or rather differentiating between p and b because we don't have p we only have b and when we talk we mix the two consonants.
3- "If you speak American English " then they will have problems differentiating the o and the u , as in cop and cup.
4- "If you speak British English"then they will have problems differntiating sounds like these "pot" and "put".

Are u interested in some grammatical difficulties ?
The present simple and the present continuous. We only have one tense for both.
The present perfect and the past continuous.Again we have one tense for both.

Are u interested in some difficult vocabulary ?
Bookstore, library and bookshop , they all have one meaning in Arabic "maktaba"
office and desk :one meaning in Arabic "maktab"

I have lots of these, and if u r interested , e-mail me on [e-mail]

Answer 2

actually i cant be sure 100% about moroccans and algerians cause i didnt meet any of them before, but we (arabs) can pronounce all english letters, and many of us speak fluent english that u cant tell they r arabs, not like indians, chinese...etc, cause they speak very good english but with a totally different accent.
the opposite is true, many arabic letters cant be pronounced by non-arabs, its a scientific fact, scientists studied those letters and found out that they are "impossible to be pronounced by non-arabs. such as
Ø®
Ø°
ص
ض
Ø·
ظ
ع
غ
ق
i know u will see those like drawing :) but i have no equivilants for them in english.
but i think moroccans and algerians can pronounce all english letters as well as we do, cause many of them speak fluent english too.

Answer 3

I once had a co-worker from Nigeria. My name is James, but the way he said it, it sounded like "Gems", so I'm guessing the long "A" sound is difficult for them.

Answer 4

I didn't know they speak English much less pronounce
it.

Answer 5

you dont know english?
