Objective Understanding transgender voice is in nascent stages. This study describes voice characteristics in treatment‐seeking trans women by comparing two validated questionnaires—Voice Handicap Index‐10 (VHI‐10) and Transsexual Voice Questionnaire (TVQ MtF )—and reports incidence of abnormal stroboscopy findings and acoustic characteristics. Methods Retrospective review of transgender patients presenting to tertiary‐care laryngology center between February 2018–February 2019. Mean VHI‐10, TVQ, and Singing VHI‐10 (SVHI‐10) scores; audio‐perceptual grade; acoustic measures; and stroboscopy findings were analyzed. VHI‐10 and SVHI‐10 vs TVQ MtF were compared. Results Sixty‐one trans female patients (mean age: 32 ± 11 years) were analyzed. Mean duration since start of transition was 41.5 ± 61 months. Sixty‐nine percent presented full‐time female in all contexts. Pathologic stroboscopy findings were found in 5%. Mean questionnaire scores were 16 ± 10 (VHI‐10), 19 ± 13 (SVHI‐10), and 81 ± 22 (TVQ MtF ). Correlation between VHI‐10 and SVHI‐10 versus TVQ MtF was weak, R = 0.47 ( P = .053) and R = 0.35 ( P = .17), respectively. Mean audio‐perceptual grade was 0.27 ± 0.15. Mean Cepstral Spectral Index of Dysphonia (CSID, sustained vowel) was 8.5 ± 21.9. Mean Cepstral Peak Prominence (CPP) Fo and CPP Fo SD in rainbow passage were 157.3 ± 16 and 59.4 ± 15.9, respectively. Conclusion Trans women report perceived voice handicap in speaking and singing, which appears separate from gender‐related voice/communication concerns. This study is the first to report stroboscopy findings in transgender individuals, with 5% being abnormal. Stroboscopy is encouraged before initiating voice intervention in transgender patients. Preliminary evaluation suggests weak correlation between VHI‐10 or SVHI‐10 and TVQ MtF but requires further investigation. TVQ MtF may provide information which more specifically reflects voice concerns of trans women as compared to VHI‐10 and SVHI‐10. Level of Evidence 4 Laryngoscope , 131:1071–1077, 2021
