Studies of non-classical styles of singingJohan Sundberg
Recently some investigations have been completed at KTH where the goal was to describe what characterised the voice usage in various non-classical styles of singing, such as "twang", belting, blues, rock, jazz..... Along with fundamental frequency, subglottal pressure and glottal adduction are the main physiological voice control parameters. Subglottal pressure is accessible as the oral pressure during the occlusion for the consonant /p/. Glottal adduction is generally estimated from analysis of the voice source by inverse filtering of the pressure or the flow signal. Some examples will be presented of different vocal styles with regard to their mean pitch range, subglottal pressure range and adduction range and synthesis.
