What is Vowel Dependence in Spectral Tilt Analysis about?

This study investigates the spectral tilt of vowels using audio signals and electroglottography (EGG) in a Swedish corpus of 5277 sentences. It finds that while audio spectral tilt shows vowel dependence, EGG spectral tilt does not, with EGG values becoming steeper as sound pressure increases. The research highlights the differences in how these two methods capture vocal characteristics, suggesting implications for voice synthesis and analysis.
