One of the greatest hurdles in the transition of transgender persons is that voice, speech and communication are not congruent with the desired gender. Since hormone treatment does not affect the voice in male-to-female transgender persons (trans women), speech therapy is the treatment of choice to develop a more feminine communication. Speech therapy must focus on aspects of communication that play an important role in listener perceptions of the speakers gender. Results of a systematic review and meta-analysis showed that those aspects are primarily fundamental frequency of the voice and resonance. However, effectiveness studies of speech interventions in transwomen are extremely limited and show methodological limitations. The purpose of this project is to investigate the short-term and longterm impact of speech exercises for pitch and resonance on (a) acoustic voice characteristics, (b) listener perceptions of femininity using a visual analogue scale and binary gender identification (male versus female voice), and (c) self-perception and psychosocial functioning in trans women using a randomized sham-controlled trial and cross-over design.
Laryngeal disorders after childhood cardiac surgery is a complication well described in the literature. However, the long term progression of the affected children has never been studied (all the studies stopped before 2 years of follow up).
Objectives: Transoral Laser Microsurgery (TLM) is widely used in for treating T1/T2 glottic cancers. Hyaluronic acid (HA) is a safe and commonly-used injectable in vocal cord augmentation. We report on the results of our single-blinded, randomized-controlled trial (RCT) investigating the impact of intra-operative HA injection on voice outcomes in early glottic cancer. Methods: Patients with T1/T2 glottic cancers were randomized to the treatment group (n=14) receiving HA injection to the unaffected cord during TLM; or the control group, receiving no injection (n=16). All patients had a Voice Handicap Index-10 (VHI-10) questionnaire and a Maximum Phonation Time (MPT) measurement preoperatively and at 3, 12 and 24 months post-operatively. Mean change in VHI-10 and MPT, between pre-operative and post-operative time points, and between the time points, were compared. Survival estimates were also calculated.
Scientific literature supports that teachers are at greater risk for voice disorders than the general population. In the classroom, the teacher's voice represents the main communication tool. Optimal voice use is indispensable to ensure effective teaching and preserve the teacher's vocal health. This project investigates how virtual reality (VR) facilitates the learning of effective vocal skills and their application in real-world contexts. Based on acoustic analyses and self-assessment scales, the investigators compare 100 future teachers randomly assigned in two groups. The experimental group (n=50) receives a voice training by VR simulations and voice information. The control group (n=50) only receives voice information.
The current project is designed as phase 1 study conducted to improve/enhance normal voice. Fifteen Thirty non-treatment seeking individuals, with no identifiable vocal pathology on laryngeal examination, will be randomized to one of two groups; 1) Voice therapy delivery without App (control/standard of care), 2) Voice therapy delivery with app (experimental). Participants in both groups will attend weekly voice therapy sessions (for 6 weeks) with the PI and Co- I (Joseph Stemple). Control group participants will be provided with an audio file of the exercises, and an exercise log sheet to track progress. Experimental group participants will use the smartphone app, which allows participants to record home practice sessions in real time and upload sessions to the app server for the clinician to access and track. Three-wave surveys will be conducted at the baseline, four weeks and 6 weeks after the intervention. Other data sources include study administration, exercise logs, app data, and clinical assessment.
Current semi-occluded vocal tract therapies limit the type of vocalizations that can be produced to single vowels, which does not promote learning of the healthy voice behavior in connected speech or generalization to conversation. However, recent preliminary results using a semi-occluded mask indicate that the use of certain mask port diameters may allow for natural speech production while increasing supraglottal pressure and impedance, and thereby result in elicitation of voice with increased efficiency. In addition, the use of a semi-occluded mask provides the possibility for a better transition from phonating single phonemes in therapy to training the target therapy techniques in connected speech.
Two voice therapy methods are compared. Activity noise levels and vocal load of teachers during teaching in primary school classrooms are evaluated. Acoustic and Workshop Interventions are implemented in order to reduce noise level during lesson.
Voice disorders in teachers have a significant impact on communication, quality of life, and economic costs to the healthcare system. We need to advance the prevention of voice disorders in teachers by testing an online telepractice model with synchronous (in real-time) and asynchronous (stored and accessed later) methods. The current study will investigate the effectiveness of the theoretically-driven Global Voice Prevention Model (GVPM) delivered by two methods; 1) online telepractice (synchronous and asynchronous) and 2) traditional, in-person for vocally healthy physical education and vocal music student teachers. Effectiveness of the model will be assessed by voice-related measures captured daily on a smartphone app during student teaching, matching the asynchronous aspects of the telepractice model and representing the effects of vocal loading from teaching.
This study investigates in patients whose primary complaint is either neck pain and/or a voice disorder , if there are any correlations between subjective neck and voice symptoms according to Neck Disability Index (NDI) and Voice Handicap Index (VHI). NDI and VHI questionnaire results for voice disordered patients will be retrieved from the data base of the Department of Phoniatrics and Speech Pathology, University Hospital Zurich. Neck pain patient questionnaire data will be retrieved from an ongoing study. The agreement between subjective neck handicap (NDI) and voice handicap (VHI) will be statistically analysed.
