In some cases, they risked their lives to make their contributions recognized by the world. From Columbusâ discovery of the Americas to Hillaryâs quest up Mount Everest, the names of these great pioneers will remain important for centuries to come as the most famous explorers of all time.
The unvoiced French consonant sounds are CH, F, K, P, S, and T. All unvoiced consonants have a voiced equivalent; i.e., the pairs are pronounced in the same place in the mouth/throat but the first is unvoiced while the second is voiced: CH - J. F - V. K - G.
Some consonant sounds are voiced and some are voiceless. A voiceless sound is one that just uses air to make the sound and not the voice. You can tell if a sound is voiced or not by putting your hand gently on your throat. When you say a sound, if you can feel a vibration it is a voiced sound. Voicing is important because sometimes it's the only difference in the pronunciation of two very different words, such as 'bet' and 'pet'. Bet /bet/ - the /b/ sound is voiced. Pet /pet/ - the /p/ sound is voiceless. Sorry, you can't see the video for this topic :-(. However, you can download it to play on your computer.
