Voice interventions for transgender individuals can address several speech and voice parameters - fundamental frequency, resonance, intonation, rhythm, and intensity. In this study, we focus on fundamental voice frequency and build on existing research to test one technique that has been shown in a preliminary study to effectively adjust fundamental voice frequency in line with clients' goals.
More specifically, we employed an adaptation of melodic intonation therapy (MIT) to assess whether it can raise trans women's average fundamental frequency to a significant degree. Eleven trans women participated in two one-to-one therapy sessions, four weeks apart.
Results pointed to a statistically significant rise in both their singing and speaking fundamental frequencies following the adapted MIT therapy sessions. Participants were also successful in imitating upward fundamental frequency contours when singing and in producing them independently in the speech modality.
Longitudinal studies are warranted to determine whether the observed positive results translate into long-term benefits.
针对跨性别个体的语音干预可以解决几个语音和声音参数——基频、共振、语调、节奏和强度。在这项研究中，我们专注于基本的语音频率，并在现有研究的基础上进行测试，以验证一种在初步研究中已证明可有效调整基本语音频率以符合客户目标的技术。
更具体地说，我们采用了旋律语调疗法（MIT）的改编版，以评估它是否可以显著提高跨性别女性的平均基频。11 名跨性别女性参加了两次一对一的治疗课程，间隔四周。
结果表明，在接受改编后的 MIT 治疗课程后，她们的唱歌和说话的基频都有了统计学上的显著提高。参与者在唱歌时也成功地模仿了向上的基频轮廓，并在言语模式中独立产生了这些轮廓。
需要进行纵向研究，以确定观察到的积极结果是否转化为长期收益。
