In the seventh version of their Standards of Care, WPATH recognizes that, as each person is unique, so is the person's gender identity. The goal of speech-language therapists/ pathologists is to help transgender people develop voice and communication that reflects their unique sense of gender. When outer expression is congruent with an inner sense of self, transgender people may find increased comfort, confidence, and improved function in everyday life. Transgender voice and communication is a relatively new area of practice within speech-language pathology/therapy and this document is intended to support clinicians and researchers working in this field. It begins with a review of the evidence-based literature in transgender voice and communication. The paper then discusses these clinical topics: trans-specific voice-and-communication assessment, voice feminization protocols and voice feminizing surgeries. There is also a section on speech and voice masculinization-an area that has received little previous attention. As minimal standards have yet to be established in this field the paper concludes with recommendations for good clinical care.

“…[82] assessed the effects of a unique pitch-raising surgical technique designated “upper displacement of the anterior commissure” (UDAC) and compared the results with those obtained through cricothyroid approximation (CTA). The authors used 20 excised human larynges to determine vocal fold length, F 0 , and videokymography parameters preoperatively, post-CTA, and post-UDAC.…”

Experiments on human and on animal excised specimens as well as in vivo animal preparations are so far the most realistic approaches to simulate the in vivo process of human phonation. These experiments do not have the disadvantage of limited space within the neck and enable studies of the actual organ necessary for phonation, i.e., the larynx. The studies additionally allow the analysis of flow, vocal fold dynamics, and resulting acoustics in relation to well-defined laryngeal alterations. Purpose of Review This paper provides an overview of the applications and usefulness of excised (human/animal) specimen and in vivo animal experiments in voice research. These experiments have enabled visualization and analysis of dehydration effects, vocal fold scarring, bifurcation and chaotic vibrations, three-dimensional vibrations, aerodynamic effects, and mucosal wave propagation along the medial surface. Quantitative data will be shown to give an overview of measured laryngeal parameter values. As yet, a full understanding of all existing interactions in voice production has not been achieved, and thus, where possible, we try to indicate areas needing further study. Recent Findings A further motivation behind this review is to highlight recent findings and technologies related to the study of vocal fold dynamics and its applications. For example, studies of interactions between vocal tract airflow and generation of acoustics have recently shown that airflow superior to the glottis is governed by not only vocal fold dynamics but also by subglottal and supraglottal structures. In addition, promising new methods to investigate kinematics and dynamics have been reported recently, including dynamic optical coherence tomography, X-ray stroboscopy and three-dimensional reconstruction with laser projection systems. Finally, we touch on the relevance of vocal fold dynamics to clinical laryngology and to clinically-oriented research.
