I investigated solo voice acoustics. Specifically, I scanned singers with MRI, reconstructed
their vocal tract in 3D to simulate numerically their impulse response. I 3D-printed their vocal tract and measured their acoustic impulse response in an anechoic chamber. These were the first full vocal tracts printed in the world . I found the spectral impact of morphological features of the hypopharynx on a singer’s voice. I created a new metrics that determines the voice classification and spectral gaussian curve depending on morphological dimensions.
