Voice source differences between falsetto and modal registers in counter tenors, tenors and baritones.
Vocal registers are generally assumed to be associated with the voice source, i.e. the pulsating transglottal airflow. The waveform of this airflow was analysed by inverse filtering in professional singers, four counter tenors, five tenors, and four baritones singing the syllable [pae:] in soft, middle, and loud voice in modal and falsetto/counter tenor register. Subglottal pressure, estimated ...
متن کاملProfessional opera tenors' vocal tract configurations in registers.
OBJECTIVE Tenor singers may reach their top pitch range either by shifting from modal to falsetto register or by using their so-called 'voix mixte'. MATERIAL AND METHODS In this study, dynamic real-time MRI of 8 frames per second was used to analyze the vocal tract profile in 10 professional opera tenors, who sang an ascending scale from C4 (262 Hz) to A4 (440 Hz) on the vowel /a/. The scale ...
متن کاملOn Büchi One-Counter Automata
Equivalence of deterministic pushdown automata is a famous problem in theoretical computer science whose decidability has been shown by Sénizergues. Our first result shows that decidability no longer holds when moving from finite words to infinite words. This solves an open problem that has recently been raised by Löding. In fact, we show that already the equivalence problem for deterministic B...
متن کاملOn Parameterized One-Counter Automata
We consider the model-checking problem for freeze LTL on one-counter automata (OCAs). Freeze LTL extends LTL with the freeze quantifier, which allows one to store different counter values of a run in registers so that they can be compared with one another. As the model-checking problem is undecidable in general, we focus on the flat fragment of freeze LTL, in which the usage of the freeze quant...
متن کاملOn Groups and Counter Automata
We study finitely generated groups whose word problems are accepted by counter automata. We show that a group has word problem accepted by a blind n-counter automaton in the sense of Greibach if and only if it is virtually free abelian of rank n; this result, which answers a question of Gilman, is in a very precise sense an abelian analogue of the Muller-Schupp theorem. More generally, if G is ...
