Note about length for speakers whose language doesn't make a difference between short and long vowels:
In English, vowels may be short or long. The phonetic symbols followed by colon (:) are long vowels.
Short vowels are very short, and long vowels usually take more than double the time to pronounce. All the English vowels sound different, but if you pronounce them with a foreign accent some of them may be confused; respecting the short-long difference will help natives to understand you. If you practise reading using ®Motion Phonics make sure your motions are short or long to match the length of vowels, that will help you to master the time difference until it comes naturally to you
