“…Increase in jitter% shows that voice quality is rough or dysphonic. 23 Sanal et al 24 reported that mean F0 was 137 Hz, jitter% was 16.30, shimmer% was 14.51 and MFT was 5.08 in patients with frontolateral laryngectomy; while these values were mean F0 155 Hz, Jitter% 19.05, Shimmer% 15.45 and MFT 3.3 s in cricohyoidopexy cases and mean F0 147 Hz, Jitter% 15.40, Shimmer% 21.73 and MFT 7.05 s for cordectomy cases. MPT was very low in all partial laryngectomy patients and jitter% and shimmer% values appeared to be much increased.…”

Introduction: To evaluate the effect of surgery type and adjuvant radiotherapy (RT) on voice quality and quality of life in patients with larynx cancer. Methods: 38 patients with larynx cancer (37 males, 1 female; mean age 63.6 ± 9.63 years) were included in this study. The parameters including tumor localization, TNM staging, and type of surgery performed, adjuvant/primary RT intake and recurrence were recorded. All participants filled voice handicap index (VHI-10) and University of Washington Quality of Life Questionnaire version-IV (UWQOL-4). Voice analysis was performed by Xion Endo Strop-DX system. Questionnaire scores and voice parameters were compared between groups. Results: There was a statistically significant low mean values of VHI detected within the group of stripping/cordectomy compared to groups of partial or total laryngectomy. In the group without RT, the mean values of SPLmin, MPT, pain, appearance, swallowing and chewing subgroups of UWQOL scale were higher than the group treated with RT. There was a negative correlation identified between VHI and QOL parameters. Conclusion: In advanced stage larynx cancer, increased surgical manipulation and adjuvant RT requirements decrease QOL. As a result early diagnosis of disease and treatment is very important. As subjective voice quality increases QOL scores rise, indicating the importance of referring patients for voice therapy and psychotherapy after treatment.

“…The jitter refers to the change in the duration of consecutive glottal cycles, while the shimmer reflects the changes in amplitude of consecutive glottal cycles. The study described in (Silva et al (2009)) focused on a comparative evaluation of different methods to estimate the amount of jitter in speech signals with a target on their ability to detect pathological voices. Results showed that there were significant differences in the performance of the various algorithms, the best techniques being not necessarily the most commonly used.…”

The great majority of current voice technology applications rely on acoustic features, such as the widely used MFCC or LP parameters, which characterize the vocal tract response. Nonetheless, the major source of excitation, namely the glottal flow, is expected to convey useful complementary information. The glottal flow is the airflow passing through the vocal folds at the glottis. Unfortunately, glottal flow analysis from speech recordings requires specific and complex processing operations, which explains why it has been generally avoided. This paper gives a comprehensive overview of techniques for glottal source processing. Starting from analysis tools for pitch tracking, detection of glottal closure instant, estimation and modeling of glottal flow, this paper discusses how these tools and techniques might be properly integrated in various voice technology applications.

“…Another study 22 examined the use of a new proposed measurement for frequency perturbation called LocJitt, which provides better accuracy.This measurement was considered more reliable when used either with MDVP or with Praat. The only case in which Jitt exceeds the LocJitt measurement was when relative jitter was used in Praat.…”

Resumo:Este estudo tem como objetivo descrever, a partir de revisão de literatura, a confiabilidade da análise acústica utilizando o Multi Dimensional Voice Program,comparação de suas medidas com outros programas de análise acústica; caracterização de vozes de diferentes grupos; e sua utilização para verificar os efeitos e eficácia de diferentes procedimentos terapêuticos. Realizou-se levantamento bibliográfico que priorizaram estudos dos últimos cinco anos, incluindo-se artigos cujo objetivo estivesse de acordo com o interesse da presente revisão. A pesquisa foi realizada nos bancos de dados das bases Lilacs, BIREME, PubMed, MedLine, Scielo e Google Schoolar, por meio dos descritores acoustic, speech acoustics e voice. As medidas mais utilizadas são frequência fundamental, jitter, shimmer e proporção harmônico-ruído. As medidas de tremor não apresentam boa confiabilidade. As medidas mais consistentes que apresentam alta concordância com outros programas de análise acústica são as relacionadas com a frequência fundamental. Diversos estudos buscam caracterizar diferentes tipos de vozes tais como as de sujeitos sem alterações vocais de ambos os sexos, buscando estabelecer parâmetro de normalidade para diferentes grupos populacionais. Além disso, alguns estudos caracterizam vozes com diferentes distúrbios. A análise acústica é um recurso objetivo e necessário na avaliação de pacientes com distúrbio vocal e, principalmente, na comparação de diversos tipos de tratamento.
