RESUMO
OBJECTIVE: The study aimed to investigate the vocal range of oral contraceptive (OC) users aged between 20 and 30 years. STUDY DESIGN: This is a cross-sectional study. METHODS: Forty-eight women aged 20-30 years who used low-dose OCs and 24 age-matched women who did not use oral monophasic contraceptives (w/oOC) were enrolled. Acoustic analysis was performed using the Motor Speech Profile program, Model 4341 (Kay Elemetrics Corp). Data were analyzed using generalized estimating equation. RESULTS: In the w/oOC group, the highest vocal tones in the sentence uttered using exclamatory intonation were similar in the follicular phases of two cycles (F1: 289 ± 46 Hz; F2: 284 ± 61 Hz). In the luteal phase of the first cycle, the vocal tones were lower, whereas in the second cycle they were higher than the tones in both follicular phases (L1: 274 ± 42 Hz; L2: 291 ± 62 Hz) (P = 0.056). In the highest vocal tones of the same sentence uttered using exclamatory intonation, the OC group showed lower tones (284 ± 53 Hz) than the w/oOC group (298 ± 44 Hz) (P = 0.048). In the lowest vocal tones of utterances of joy, the OC group showed higher values (180 ± 39 Hz) than the w/oOC group (169 ± 44 Hz) (P = 0.024). The close proximity of the highest to the lowest values of utterances of joy in the OC group (321 ± 59 Hz and 180 ± 39 Hz), when related to the w/oOC group (338 ± 65 Hz and 169 ± 44 Hz), suggests a reduced vocal modulation. CONCLUSIONS: The present findings demonstrate that the use of low-dose OCs influences the vocal range of women during menacme.

OBJECTIVES: In the female life cycle, hormonal fluctuations may result in impaired verbal efficiency and vocal worsening during the premenstrual phase. Oral contraceptives may interfere with vocal range. Voice, resonance, and articulation variations clarify speech content. To investigate the phonoarticulatory sounds produced by oral contraceptive users aged between 20 and 30 years. STUDY DESIGN: This is a cross-sectional study. METHODS: Our study included four groups of women (n = 66): two groups used low-dose oral contraceptives and two groups did not use any oral contraceptives. Questionnaires and sound records were used. Acoustic analysis was performed using the Computerized Speech Laboratory program, Model 4341 (Kay Elemetrics Corp, Lincoln Park, New Jersey). The statistical analysis of the SPPS database, version 13.0, was performed by means of generalized estimating equation. RESULTS: In the groups that did not use oral contraceptives, sustained vowel tones were more acute in the two phases and cycles of women older than 25 years (w/oOC1, 175 ± 74 to 190 ± 55 Hz; w/oOC2, 194 ± 56 to 210 ± 32 Hz). At the midfollicular phase (Fph) and midluteal phase (Lph) of the two cycles, the speed of the speech was slower in this group (w/oOC1: Fph, 5.3 ± 1.6/s and Lph, 5.4 ± 1.4/s; w/oOC2: Fph, 4.5 ± 1.7/s and Lph, 4.8 ± 1.1/s). In both groups that used oral contraceptives, there was a higher modulation frequency in the sentences when compared with nonusers (OC1, 33 ± 10 Hz; w/oOC1, 28 ± 10 Hz; OC2, 34 ± 10 Hz; w/oOC2, 27 ± 10 Hz). Vocal intensity was closer between the OC1 (62 ± 4 dB), w/oOC1 (61 ± 3 dB), and OC2 (63 ± 4 dB) groups when compared with the w/oOC2 (67 ± 6 dB) group. CONCLUSIONS: We demonstrated hormonal influences on speech articulation of contraceptive users and nonusers.

OBJETIVOS: comparar as características fonoarticulatórias de mulheres no menacme e na pós-menopausa. MÉTODOS: foram verificados parâmetros acústicos em tons de voz, sua estabilidade, modulações de entonações, ritmo e velocidade de fala. Quarenta e cinco mulheres na pós-menopausa há três anos ou mais e sem terapia de reposição hormonal e, quarenta e cinco mulheres no menacme, com ciclos menstruais regulares e sem medicação hormonal responderam um questionário e gravaram produções verbais. As análises acústicas foram realizadas com o programa Motor Speech Profile da Key Elemetrics. Utilizou-se o teste t de Student para resultados com distribuição gaussiana e o teste Mann-Whitney quando houve distribuição assimétrica. RESULTADOS: no grupo pós-menopausa houve maior consistência na lentificação do ritmo e redução de velocidade fonoarticulatória. CONCLUSÕES: o melhor conhecimento nesta área permitirá a elaboração de estratégias para oferecer melhor qualidade de vida para mulheres na pós-menopausa, em especial para aquelas que utilizam a voz profissionalmente.

Human verbal expression requires coordinated interaction among cortical, neuromuscular, and peripheral events. It is affected by hormonal factors and shows different characteristics in reproductive age and postmenopausal women. The present study compared phono-articulatory characteristics between women in reproductive age postmenopausal. Acoustic variations in fundamental frequency, voice sustenance, formants, vocal intensity, and verbal diadochokinesis were measured. Forty-five women in reproductive age with regular menstrual cycles and taking no hormonal contraceptives and 45 postmenopausal women receiving no hormonal replacement therapy for at least 3 years were interviewed, and their verbal productions were tape-recorded. Acoustic analyses were performed using the Kay Elemetrics Motor Speech Profile (Lincoln Park, NJ). Student t test was employed to compare data between the two groups when they presented normal distribution and Mann-Whitney test when they were asymmetrical. Results showed a greater variability in vocal sustenance, less variation in formants, and verbal diadochokinesis in postmenopausal women. There were no significant variations in fundamental frequency and vocal intensity. These results emphasize the need of a multidisciplinary integrated research, when assessing phono-articulatory processes after the menopause. A better understanding in this field will make it possible to elaborate strategies to offer a better life quality for postmenopausal women.

During the female vital cycle verbal processes are influenced by secondary effects of steroid hormones. Verbal expression abilities favor more effective interpersonal communications. Verbal motor fluency is produced by the synchronization among voice, resonance and articulation. The present study compared phono-articulatory characteristics between women in reproductive age and postmenopause. Acoustic variations in vocal intonation, speed of the speech and the pause pattern were measured. Forty-five reproductive age women with regular menstrual cycles and taking no hormonal contraceptives and 45 postmenopause women receiving no hormonal replacement therapy for at least 3 years were interviewed and their verbal productions were recorded. Acoustic analyses were performed using the Kay Elemetrics Motor Speech Profile. Student's t-test was employed to compare data between the two groups when they presented normal distribution, and Mann-Whitney test when they were asymmetrical. Results showed that in the postmenopause group pause pattern was longer, the speed of the speech was slower, there was a vocal deepening without reduction of the vocal extension and there was also less vocal stability. A better understanding in this field will make possible to elaborate strategies to offer a better life quality for postmenopausal women.
