- The agreement between a transducer and a microphone in the analysis of a synthesized vowel—Using a laboratory model as a preliminary experimentPublication . Pestana, Pedro; Byrne, Allison; Alegria, Rita; Araújo, André; Melo, Celso; Brasil, Christina César Praça; Manso, Maria Conceição; Guerreiro Martins Araújo, Pedro AndréThe objective of this study was to assess the agreement between the acoustic parameters of synthesized vowels, as measured by a piezoelectric transducer and a microphone. The central hypothesis posited that there would be a substantial degree of concordance between the acoustic parameters obtained by these two methods. A laboratory experiment was conducted using synthesized vowels. Acoustic parameters were recorded simultaneously using a microphone and a piezoelectric transducer. Vowels were synthesized using Madde software, with variations in fundamental frequency (fo) and amplitude level. Acoustic signals were captured by a Shure MX153 T microphone and a Shadow SH712 piezoelectric transducer. Signals were recorded using a Behringer FCA1616 audio interface and analyzed using Sopran and VOXplot software. Bland–Altman plots were used for statistical comparison of acoustic parameters. The degree of agreement between the microphone and the transducer varied according to acoustic parameters. Excellent agreement was observed for jitter, mean fo, fo standard deviation, and fo range. Good agreement was found for tilt, equivalent continuous sound level, harmonics-to-noise ratio from Dejonckere, high frequency noise, minimum fo, and maximum fo. Moderate agreement was observed for slope, amplitude difference H1–H2, shimmer, harmonics-to-noise ratio, smoothed cepstral peak prominence, and period standard deviation. While there was moderate to high agreement between the two methods for several acoustic parameters, discrepancies were noted. The microphone exhibited a tendency to record slightly higher values for the majority of the parameters; however, the transducer did demonstrate heightened sensitivity for certain parameters. The findings indicate that neither method can be universally interchanged with the other, and the selection of a method should be contingent on the particular requirements of the analysis.
- Evaluation of the ability to sing easily: Adaptation and validation to the European Portuguese languagePublication . Pestana, Pedro Melo; Freitas, Susana Vaz; Alegria, Rita; Manso, Maria ConceiçãoA number of voice assessment tools are currently in use in both clinical and research settings. The Evaluation of the Ability to Sing Easily offers a comprehensive self-assessment tool designed for singers. EASE captures subtle changes in vocal health by inquiring about the subject's current experience. This makes Evaluation of the Ability to Sing Easily a valuable tool for the early identification of vocal issues and the monitoring of a singer's overall vocal health. Objective: This study aimed to adapt and validate the Evaluation of the Ability to Sing Easily for European Portuguese and assess its psychometric properties. Methodology: A five-step cross-cultural adaptation process was followed, including forward translation, backward translation, committee review, pilot testing, and finalization. The Evaluation of the Ability to Sing Easily for European Portuguese was then administered to 120 singers (Fado and Choir) to evaluate internal consistency and known-groups validity. Results: The pilot test identified and resolved ambiguities in seven Evaluation of the Ability to Sing Easily for European Portuguese items. Internal consistency was high, with Cronbach's alpha exceeding 0.80 for the Evaluation of the Ability to Sing Easily scale and sub-scales in both Fado and Choir singers. Fado singers reported higher vocal fatigue scores, while Choir singers reported higher Pathologic Risk Indicators scores. A weak negative correlation between singing load and PRI scores was observed in Choir singers. Conclusion: The Evaluation of the Ability to Sing Easily for European Portuguese demonstrates good internal consistency and cultural relevance for Portuguese singers. Known-groups validity suggests potential differences in vocal function between Fado and Choir singers. Further research is needed to explore external validity, test-retest reliability, and applicability to other singing styles.
- A intervenção do terapeuta da fala em meio aquáticoPublication . Neves, Rafaela; Peixoto, Ana; Alegria, RitaA Terapia da Fala em meio aquático é uma prática recentemente realizada nos Estados Unidos da América e em alguns países da Europa, sendo que na atualidade estão a ser realizados os primeiros estudos sobre esta temática. É com base nas propriedades físicas e sensoriais da água, que estes profissionais atuam sobre aspetos físicos (voz; motricidade orofacial), bem como psicossociais (comunicação).
