Esperanto is usually considered to be between 5-7 times quicker to learn than most national languages.
Esperanto is completely phonetic.
A single, unique letter represents every sound whenever it occurs.
There are no exceptions, silent letters, phonemes, or variations due to position.
The emphasis is always on the second-last syllable, which makes correct oral reading possible from the first lesson.
The advantage of this is that all students get the chance to organize their ideas, to select appropriate words and tone, and express their ideas and feelings, in their new language.
