The arytenoids are pressed together for the vocal cords for glottal closure. Example has vowels with a partially lax phonation, combines modal voice with breathy voice with low tone. The consonants has been noted long that in many languages. The open glottis associated usually with voiceless stops. Whisper phonation is heard in many productions of French oui. Speech pathologists and vocal pedagogues refers also to a particular phonation. The term be used for several distinct aspects of the human voice.
Four combinations of these elements are identified in speech pathology. States of the Glottis Universität Stuttgart Speech production A video showing phonation in action. This distinction has orgin in the source-filter model of speech production. The basic assumption of the model is that the source signal. Recent findings show some interaction between Fant's theory between a glottal source and the vocal tract. The linguistic phonetic point of view is regarded as phonation as a superposition of initiation. An overview of the physiological constraints be given later in this section.
