Fizziq//Vowels//Discover the different ways in which we pronounce vowels//In the Instruments tab select the Sound spectrum. The spectrum let you analyse the frequencies of pure sounds that make up a complex sound//Sing the vowel -i- for several seconds and record the spectrum//Analyze the graph. What do you see? How many peaks appear on the graph? Can you find a mathematical relationship between the peak frequencies?//The lowest frequency peak is the fundamental frequency, the other peaks are the harmonics. What is the fundamental frequency and how many harmonics do you find?//Sing the vowel -o- and record the sound spectrum. What do you see? How many harmonics do you find? What is the difference with the -i-?//Repeat this experiment for the other vowels. Can you imagine vowel groups that seem to create the same types of harmonics?//These are the cavities in your mouth that create more or less harmonics. Why do some vowels produce more harmonics than others?//Try singing the sound of a growling dog. What do you see?//Summarize your results in your notebook with text and photos
