The audio here is generated speech. A recorded human voice for this lesson is on the way.
The two sounds
G and K are made at the back of the mouth: the back of your tongue rises and touches the soft part of the roof of your mouth, then lets go. G is voiced, with a buzz; K is voiceless, with a puff of air. Say "guh" and "kuh" with a hand on your throat and feel the buzz come and go.
Spelling hides K in several places. "C" before a, o and u sounds like K: cat, cold, cup. "CK" at the end of a word is K: back, clock. And some letters are silent: the K in "knee", "know" and "knife" is not pronounced at all.
Hear the difference
Tap each word. Then test your ear.
At the end of a word, the vowel before G is longer: "bag" stretches, "back" is short.
Say it out loud
Tap a sentence to hear it. Say it after the voice.
"Know" has a silent K. The sound starts with N.
Practice · 3 min
Say each sentence after the model. Pay attention to the start of every word with C, K or G. In the last sentence, make sure "know" starts with N and "cake" and "can't" both have a clear K.
Say it today
Use it once in a real conversation before tomorrow. Out loud counts, even to yourself.
