    Una propuesta de texto fonológicamente equilibrado: El ratón Arturo, la adaptación al español de Arthur the Rat
    (Universidad Complutense de Madrid (España). Ediciones Complutense, 2024-05-07) Casado Mancebo, Mario; Polo Cano, Nuria; Teira Serrano, Celia
    Para recabar datos lingüísticos se suelen usar textos fonéticamente (fonológicamente) equilibrados. Una búsqueda de este tipo de textos en español descubre pocos textos con estas características. El objetivo del presente trabajo es proponer un texto nuevo, El ratón Arturo, a partir de la adaptación de un texto original en inglés. La principal motivación para confeccionar un texto nuevo es que los que existen, y de verdad están compuestos según la distribución de fonemas de esta lengua, son demasiado cortos. La lectura de los existentes es inferior a los dos minutos, lo que dificulta calcular medidas estadísticamente fiables para un análisis vocal. La ventaja de usar este texto frente a los existentes en español es que es más largo, supera los dos minutos, y presenta un menor número de repeticiones de palabras que los que ya existen. Además, está compuesto por palabras frecuentes y oraciones sencillas. Por lo que, a pesar de la longitud mayor, no es un texto difícil de leer o de procesar porque su complejidad es similar a la de los textos anteriores. Además, puede servir para recoger datos de población adulta e infantil. Cumple con los dos requisitos de este tipo de textos: presenta al menos una ocurrencia de cada uno de los fonemas del español y estos reproducen la frecuencia de distribución de esta lengua. Además, se han recogido ejemplos de los grupos consonánticos y las codas más frecuentes. Asimismo, se ha confeccionado con palabras simples y derivadas, con acento contrastivo, con oraciones con presencia/ausencia de consonantes nasales y con oraciones con diversas modalidades oracionales. Las características específicas con las que se ha construido permiten que pueda ser utilizado tanto en la investigación fonética como para evaluar problemas motores del habla, como disartrias y apraxias, y problemas de la función vocal.

    Menopausal Voice-Related Work Limitation Scale (MenoVWL): development and validation
    (Elsevier, 2022-11-30) Filipa M.B., Lã; Mateos Ramírez, Ana; Ardura Martínez, Diego; Barro Fiuza, Mauro; Polo Cano, Nuria
    Objectives Menopause has been reported to affect the voice of female professional voice users (FPVUs). The present study aims at the development and validation of a scale to measure self-perceived menopausal voice-related limitation to work in FPVUs, henceforth the Menopausal Voice-Related Work Limitation Scale (MenoVWL). Methods Items were drawn from previous studies on impacts of sex steroid hormones on voice, available validated scales, and in-depth interviews with post-menopausal FPVUs. A preliminary version with 16 items was evaluated by a panel of 15 voice experts. The resulting revised version was filled in online, together with questions on current endocrinological reproductive status and related symptoms, history of amenorrhea, professional occupation, and demographic information. Responses concerning only professional voice users were selected and inclusive and exclusive criteria were applied for correct allocation of participants into pre- and post-menopausal stages within a restrict age range;192 responses were subject to factorial analysis for MenoVWL validation. Cronbach's alpha measured internal reliability. The scale was tested by comparing MenoVWL scores between pre- and post-menopausal FPVUs (98 and 94, respectively). Results Thirteen items were retained from the expert panel evaluation. Items presented a high Content Validity Index (.94 out of 1) and high Item Acceptance Ratio (86.25 %). Both exploratory and confirmatory factorial analysis rendered one dimension scale with an excellent internal consistency (Cronbach's alpha = .9). The results of a Mann-Whitney test showed a higher MenoVWL score for post- as compared to pre-menopausal FPVUs (Z = - 2.818; P = .005). Conclusions MenoVWL is a comprehensive and validated scale with a known factor structure. It constitutes a health care and safety outcome self-perceived measure of value to the early detection of voice-related limitations to work in FPVUs during menopause.

    Fundamental frequency variations across the menstrual cycle and the use of an oral contraceptive pill use
    (American Speech-Language-Hearing Association (ASHA), 2020-04-27) Filipa M.B., Lã; Polo Cano, Nuria
    Purpose Concentrations of sex steroid hormones—estrogens, progesterone, and testosterone—have been associated with premenstrual and menstrual vocal symptoms. However, the extent to which these symptoms may be reflected on acoustical features of the voice is still debated. This study investigates variations in fundamental frequency (fo) and related parameters in connected speech across phases of the menstrual cycle and during the use of a combined oral contraceptive pill (OCP). Method Electrolaryngographic recordings were made, and blood samples were collected at three different phases of the menstrual cycle—menstrual, follicular, and luteal—for placebo and OCP use. These two conditions were blindly and randomly allocated in the study. Speaking fo (SFF), SFF standard deviation, SFF rate of change, SFF slope, maximum and minimum fo, and fo range were extracted for nine healthy females while reading a phrase from the Rainbow Passage. Concentrations of sex hormones were analyzed in serum. Nonparametric statistical tests were carried out to assess differences between phases and conditions. Results SFF, its standard deviation, and maximum fo were significantly different between phases of the menstrual cycle for placebo use only. Menstrual phase showed the lowest values. Maximum and minimum fo were significantly different between placebo and OCP use for menstrual and follicular phases, respectively. Conclusions Fluctuations in sex steroid hormones across the menstrual cycle alter fo in speech more than a particular hormonal concentration. OCP use seems to have a stabilizing effect on the voice relative to fo and related parameters in speech.
