By means of a laringostroboskopi-chesky research (see Stroboskopiya) asynchrony, small amplitude, frequent and moderate rate of fluctuations of phonatory bands (their full smykaniye, formation of an oval or triangular crack between them), disappearance of so-called stroboscopic comfort is found. Quite often during creation of conditions for absolute synchronization of frequency of pulse light and fluctuations of phonatory bands their reductions or twitchings on certain sites are visible. Time of the maximum duration of phonation is sharply reduced.

In an initial stage of a phonasthenia its diagnosis is quite difficult. Carefully collected anamnesis, repeated surveys, consultations of the neuropathologist or psychiatrist are of great importance. At expressed F., followed by a detonirovaniye, a tremolirovaniye (so-called swing) of a sound, change of a timbre of a voice, diagnosis comes easy. In this case the diagnosis is specified at a laringostro-boskopicheoky research.
