Fourier Analysis Of Voice
To determine the Fourier spectrum of various steady-state spoken and sung vocal (vowel) sounds.
PC 486 with Rapid Systems FFT and Dual Trace Oscilloscope, microphone and amplifier for input.
The amplified microphone signal is input into the PC 486 based FFT and the wave shape and spectrum are displayed on a dual trace digital oscilloscope screen. Vocal formants for different sung vowel sounds can also be seen.
