The purpose of this study was to prospectively examine changes in gender-related voice domain of pitch measured by fundamental frequency, function-related domains of vocal quality, range, and habitual pitch level and the self-perceptions of transmasculine people during their first year of testosterone treatment.
Seven trans men received 2 voice assessments at baseline and 1 assessment at 3, 6, 9, and 12 months after starting treatment.
Vocal quality measures varied between and within participants but were generally within normal limits throughout the year. Mean fundamental frequency (MF0) during reading decreased, although to variable extents and rates. Phonation frequency range shifted down the scale, although it increased in some participants and decreased in others. Considering MF0 and phonation frequency range together in a measure of habitual pitch level revealed that the majority of participants spoke using an MF0 that was low within their range compared with cisgender norms. Although the trans men generally self-reported voice masculinization, it was not correlated with MF0, frequency range, or habitual pitch level at any time point or with MF0 note change from baseline to 1 year of testosterone treatment, but correlations should be interpreted with caution due to the heterogeneous responses of the 7 participants.
In trans men, consideration of voice deepening in the context of objective and subjective measures of voice can reveal unique profiles and inform patient care.
本研究旨在前瞻性地考察在接受睾酮治疗的第一年，通过基频测量的与性别相关的音高嗓音领域、与功能相关的嗓音质量、音域和习惯性音高水准领域的变化，以及跨性别男性的自我认知。
七名跨性别男性在基线时接受了两次嗓音评估，并在开始治疗后的3、6、9和12个月各接受一次评估。
嗓音质量测量在参与者之间和参与者自身存在差异，但总体上全年都在正常范围内。阅读时的平均基频（MF0）下降，尽管程度和速率各不相同。发声频率范围向下移动，尽管在一些参与者中增加而在另一些参与者中减少。将MF0和发声频率范围综合起来衡量习惯性音高水准发现，与顺性别规范相比，大多数参与者说话时使用的MF0在其范围内较低。尽管跨性别男性总体上自我报告嗓音男性化，但在任何时间点，它与MF0、频率范围或习惯性音高水准均无相关性，也与从基线到睾酮治疗1年的MF0变化无关，但由于7名参与者的反应存在异质性，对相关性的解释应谨慎。
对于跨性别男性，在客观和主观嗓音测量的背景下考虑嗓音变深，可以揭示独特的特征并为患者护理提供信息。
