User reviews

Too much repetition, not enough instruction

I grant I’m likely a difficult student, having tried about half a dozen online and in person voice therapists with absolutely no progress, but this was another strikeout. For, say, intonation or vowel lengthening, even in the first lesson, the instructor just has you repeat what she’s saying with no real guidance as to how one varies intonation or lengthens vowels. Pitch and resonance had slightly more instruction, but not nearly enough.

Christella VoiceUp Review

I would have liked a booklet/book explaining much more about each of three parts, especially for the price. I can’t remember if any transcripts are available for each part. The teaching takes a gradual progression to improve voice change. Practice is essential. Thank you Christella.
I have received an update which says they will see if this could be done in the next update. I hope this is possible, as I will be grateful.

Nothing but a recording app

Complete waste of time and money. There is NO instructions on how to modify your voice. The app has you read sentences and tells you what percentage male va female your voice is. It does NOT instruct you in any way on HOW to change your voice. There is no demo to see what it offers. You pay $19.99 and get absolutely nothing.

Hi, sorry to hear you think that but the app does deliver Christella's proven therapy and guidance on how to feminise your voice. It also allows you to record, analyse and monitor your voice journey - provided for free. Each of the 3 stages has a free sample to show you what is contained.

Wonderful App!

I’ve found this app extremely helpful compared to other resources I’ve used. Having gone to speech therapy as a child, this is much more like the type of practice that has helped me before.

I still supplement this with other trustworthy resources I’ve found elsewhere, but this is the best, most affordable, most helpful, and most available option for getting a speech therapy experience short of actually seeing a therapist for appointments.

I also like how it gives you a place to store your progress recordings. I had previously just emailed myself clips and stored them in email, but this allows me to scroll through and see/hear my different outcomes and progress over time which is super helpful!

Thank you so much for making it! I hope it helps others like it’s helped me!
