Christella VoiceUp: MTF Voice

Christella Antoni is a Consultant Speech & Language Therapist with over 20 years of experience and is the UK's leading expert in transgender voice modification. Christella VoiceUp teaches you how to feminize your voice, beginning with a FREE sample lesson and a FREE pitch analysis to track your progress. With just 10 minutes of daily practice, VoiceUp helps you develop a more feminine resonance, pitch, intonation, and vowel length. The complete course contains over 2 hours of voice therapy training in three stages—beginners, intermediate, and advanced—each available as in-app purchases. Each stage includes five lessons covering resonance, pitch, intonation, and vowel length, with the final lesson of each stage integrating these skills for steady control of your feminized voice. All exercises are demonstrated by Christella and based on her proven treatment model, gradually increasing length and complexity to ensure secure skill acquisition.

VoiceUp also features a free sample, a pitch analysis graph to visualize progress, and a structured path that fits a busy routine—typically 10 minutes a day. The app supports transgender individuals seeking a clinician-guided approach outside traditional therapy. The staged format, clear explanations, and consistent voice models help users track changes and build confidence as they work toward a feminized, natural voice. Users and clinicians note its accessibility, effectiveness, and usefulness as a supplement to face-to-face therapy.
