Dear Djelfa members ...
using a dictionary is very crucial in the process of learning a l a n guage ...in our case - English- we have a wide range of dictionaries such as : Oxford , webster,Cambridge and Longman..but what is the best one ?

A pronunciation dictionary is a specialized type of dictionary that does not contain definitions or example sentences. It only contains phonetic transcriptions and recordings which tell you how to pronounce words correctly.
A pronunciation dictionary has the following advantages over a general dictionary:

• More words. A pronunciation dictionary can list pronunciations for more words than a general dictionary. It can include first names, last names, geographical names, company names, trademarks, etc.
• Word forms. It can give the pronunciations for inflected forms of words — e.g. starts, started, starting — not only for the main form like start. This is especially helpful for beginner learners, who can learn that e.g. goes ends in /z/, not /s/.
• More pronunciation variants. A pronunciation dictionary can list more ways to pronounce the same word. Specifically, it can explain how to pronounce a word in a sentence. For instance, and is pronounced /ænd/, but “and all” may be pronounced /ənˈɔ:l/.
• More precise transcriptions. It can use additional symbols to give more detailed information on pronunciation.
• More authority. One can expect that a pronunciation dictionary will contain fewer errors in transcriptions than a general dictionary.
• The most important pronunciation dictionaries are : Longman and Cambridge
