Recording of the human voice, made by a
little-known Frenchman. The 10-second recording of a singer
crooning the folk song “Au Clair de la Lune” was recorded in
1860. The spectrography shows also the same song but recorded in
1931. |

Since 1996 patients with advanced laryngeal or
hypopharyngeal cancer eligible for total laryngectomie have been
treated with organ preservation with paclitaxel/cisplatin
induction chemotherapy and CT-based 3D radiotherapy. The aim of
this study was to further analyse the functional outcome
concerning the swallowing and the voice function of these
patients. |

Vocal cord paralysis is a complex
and multifactorial condition. In this study we present 23
patient with vagus nerve lesions that affect only the recurrent
laryngeal nerve and two patient with a vagus nerve lesions above
the level of the pharyngeal nerve branch.The unilateral abductor
paralysis of these patients occurs as a result of lesions caused
by following reasons. |

Vocal quality was analyzed in 20 subjects who
underwent total laryngectomy with insertion of voice prosthesis
(TL with VP) and in 10 subjects who underwent supracricoid
laryngectomy (SCL). Acoustic analysis was carried out using
Lingwaves and Praat, for sustained vowels and conversation to
obtain the fundamental frequency (F0) and jitter parameters.
Perceptual evaluations and self-assessment of voice impact on
the quality of life were also performed. Results showed
statistically significant differences between TL + VP and SCL
individuals for the mean F0 during conversation, for Roughness,
Grade of voice quality, and self-assessment of speech, with
worst results in the SCL group. |

Расстройства голоса при парезах гортани связаны
не только с нарушением подвижности голосовой складки, но и с
поражением рецепторов гортани, при котором затрудняется или
делается невозможным регулирование голосовой функции. Только
неповрежденные рецепторы обеспечивают правильное
функционирование обратной связи для контроля над голосом. |

Гипотонусная дисфония (ГД) относится к
функциональным нарушениям голоса и составляет группу наиболее
часто встречающихся заболеваний в фониатрической практике.
Особое место занимает стойкая ГД. Стойкие гипотонусные
расстройства голосового аппарата снижают работоспособность
практически здоровых лиц, а для некоторых создают угрозу
профессиональной непригодности. Поэтому лечение и профилактика
этих заболеваний имеет социальное значение. |

All surgical procedures for treatment of snoring
and obstructive sleep apnoea modify the anatomical structure of
the upper airways and the resonance characteristics of the vocal
tract; this can lead to a modification in voice quality. Purpose
of this study was to evaluate the possible modifications of the
fundamental frequency (F0) and of the frequency and amplitude of
the first (F1) and second (F2) formants of the 5 Italian vowels
after different surgical procedures for snoring, to verify if
and how these operations can influence voice quality. |

The Dysphonia Severity Index (DSI) is designed
as an objective and quantitative correlate of voice quality. It
is based on a multivariate analysis of an extended database of
more than 1000 normal and pathologic voices for the multi-center
study trial initiated by the Belgian Study Group on Voice
Disorders (Van de Heyning, et al., 1996). Per patient, more than
45 voice characteristics and measurements were collected.
Additionally, the voice quality as perceived by the clinician
and expressed by means of the grade of hoarseness was obtained
for all subjects (G from the GRBAS scale: normal, light,
moderate or severe: Hirano, 1981). The Dysphonia Severity Index
was then constructed by a multivariate statistical approach that
calculated a combination of weights variables such that the
different types of voices according to the perceived voice
quality (G) were optimally identified. |

The phonetogram as the result of a two
dimensional measurement of the range of the fundamental
frequency (F0) for pitch, displayed against the range of the
sound pressure level (SPL) for loudness, shows the dynamic
capacities of a voice at a glance. In a coordinate system,
musical pitch or fundamental frequency (Hz) is displayed on the
abscissa, SPL (dB(A)) for loudness on the ordinate. ... |
