Voice feminisation, taught in stages
Christella VoiceUp is a voice feminisation course designed and delivered by Christella Antoni, a consultant speech and language therapist, with staged lessons and a pitch graph so you can see your voice change over time.
How do I know my practice is working?
Practising a new voice alone is hard to judge. Pitch is only part of it, and without a way to hear and see what changed, it can be difficult to track your progress and know whether your practice is making a difference.
See your voice change. Pitch and questionnaire scores charted across every assessment you take.
Who wrote the course?
The course was designed by Christella Antoni, a consultant speech and language therapist who has specialised in transgender voice for more than thirty years. She recorded every lesson; Speechtools built the app and developed the advanced pitch analysis technology to provide accurate and useful feedback on voice progress. In a short video, Christella explains how people can use the app to feminise their voice. It was created because many people are unable to access specialist speech and language therapy: as Christella said in the app’s press release, “Our app has been designed to provide instant access to tried and tested techniques used daily in my clinic.” Sam Brady, Speechtools’ co-founder, made the same point in the Guardian: too few therapists are trained in transgender voice for everyone who needs one.

Common questions
Is there a subscription?
No. Christella VoiceUp is free to download, and each stage of the course is a one-off in-app purchase rather than a recurring charge.
Can I try it before buying?
Yes. Every stage has a free sample lesson, so you can hear how the teaching works before buying that stage.
What do the three stages cover?
Stage 1 teaches the essential speech and voice techniques to begin changing your voice. Stage 2 lengthens the exercises so you can hold the voice for longer. Stage 3 builds the stamina to keep it going through conversation.
What does the course actually teach?
Fifteen lessons across the three stages, around two hours in total, working on resonance, pitch, intonation and vowel length. Christella models each exercise and then leaves you time to repeat it.
