Khmer - Section B: Dependent Vowels · Day 18B: Learn ាិឹីឺ
Hello! In Section B, we will begin learning the vowels, or “sra”. The Khmer alphabet has 2 types of vowels: dependent vowels (the main type of vowel; these are attached to the consonant the sound follows), and independent vowels (which are drawn independently from other characters). Today we’ll learn the first five dependent vowels. Here they are. [ា This letter uses the "A” key.] [ិ This letter uses the "I" key.] [ី This letter uses the "W" key.] [ឹ This letter uses the "Shift" -> "I” key.] [ឺ This letter uses the "Shift" -> "W” key.] Note that the consonant ba (ប) has some special behavior: when you add vowel “ា” to consonant “ប”, it turns into “បា”. Check the message at the top of your home screen (the "lessons" page) if you have general questions or need help. Have a great lesson!

Error colors
The acceleration and deceleration lets you see where you speed up and slow down during the typing test.
Bad case is when the case is incorrect. You typed '. the' instead of '. The'.
Bad ordering is when you typed a letter too early. For example, you typed huose instead of house. The U came too early.
Doublet is when you typed a character twice. For example homee or commmunity.

WPM calculation
WPM means Words Per Minute. It is a measure of the output speed on a keyboard. Here's how it works:
- start a timer and start typing for exactly 1 minute
- count how many characters you just typed including spaces and punctuation
- divide that value by 5 (the WPM system considers a word is 5 keystrokes)
- the result is your Words Per Minute speed
