What is MtF voice feminization?

MtF Voice feminization is voice therapy for the feminization of the voice. Through repeated training, MtF voice therapy brings the voice, speech and communicative behaviour in line with the gender identity of the patient. The main objective of your MtF voice feminization voice therapy is that you learn how to develop a feminine sound by mastering certain important aspects: ‘head’ resonance, lively articulation and a feminine pattern of intonation. Learning these different aspects ensures that your basic frequency, or tone, rises in a healthy manner. Non-verbal communication is important as well: your posture, behaviour and facial expressions.

“My specific focus as a speech therapist is to help you achieve control of your voice with crucial aspects such as breathing, resonance, intonation and the combination of these aspects with a natural, non-verbal communication as a woman.” – Speech therapist Katrien Eerdekens

Hormone treatment leads to very little change in voice in MtF patients. As a transwoman, you have two options for voice feminization: speech therapy and surgery.

MtF Voice feminization: speech therapy or surgery?

As the first step of the MtF voice feminization process, we advise speech therapy. During these sessions, we offer professional guidance via MtF voice therapy to work on all aspects of voice feminization in a healthy manner. MtF voice feminization does not stop after the speech therapy sessions. You need to practice, and practice a lot. You can do this wherever you wish.

We would like to point out, however, that the professional guidance of a speech therapist during your MtF voice feminization process is very important. Practicing without such guidance can cause irritation to your vocal cords and lead to nodules or edema. MtF voice therapy will provide sufficiently good results for many transwomen. If this proves not to be the case for you, you will also need MtF voice feminization surgery for a higher pitch. Nevertheless, research has shown that MtF voice therapy both before and after voice feminization surgery is very important in order to obtain the best results. The better and more feminine your voice is before voice surgery, the better the voice will sound after the operation. In our experience, ten half-hour sessions and daily homework can already yield fine results.

“Based on my knowledge and insights as a speech/voice therapist, I am convinced that my patients have to work to achieve a healthy voice and not just an ‘acceptable feminine voice in a higher register’. That is why in some cases it is necessary to combine intensive MtF voice therapy with voice surgery.” – Speech therapist Katrien Eerdekens

Is it compulsory to first do a voice assessment before you start therapy?

Yes, because the voice therapist needs to measure your voice to see what aspects should be worked upon during therapy. The therapy emphasizes the personal and individual needs of the patient.

How many sessions of voice therapy do I need ?

This is difficult to predict. It depends on the outcome of the voice assessment and how much you practice everyday.

Can I do Voice Feminization Training online?

If you live too far away from a suitable Voice Feminization therapist, or from our clinic, we have a solution for you. Katrien Eerdekens, our voice therapist, provides online voice feminization training through Skype! You can find more information over here: https://www.2passclinic.com/voice/online-mtf-voice-feminization-training/

Will hormones (HRT) have an effect on my voice (MtF)?

No. Hormones will not affect your voice. Your voice will not become higher through hormones once you’ve gone through male puberty. The effect can not be reversed.

However, with voice feminization training you can learn how to reach a higher pitch as well as work on your resonance, and many other things which you can read more about here: https://www.2passclinic.com/voice/mtf-voice-feminization-training/

Is online voice feminization therapy and follow-up via skype effective?

Several of our patients from abroad are already following this program successfully, as you can hear in these before-and-after voice therapy sections!

Why should I follow Voice Feminization Training? Can’t I practice on my own with online videos?

A lot of instruction videos on Youtube are good, but keep in mind that these people can only speak from their own experience. It might not work the same for you, and there is a risk you’re going to start using your voice the wrong way because no one is there to guide you and correct you. This is why many people pinch their voice without realizing, which just makes the voice sound high-pitched in an artificial way. So using your voice wrong would not only be unhealthy for your voice (tension, pain, hoarseness), but the sound you produce will not sound natural.

Aside of that, voice therapy is a lot more than just voice exercises. It’s also about finding your identity, about accepting what your voice can and can’t do, and about learning to gesticulate in a feminine way. 80% Of our communication is body language. Your voice therapist is also your coach.

How often should I practice when following voice feminization training?

You should practice at least 30 minutes every day if you want to get good results. Going to a voice therapist is one thing, but practise is what is going to determine whether you succeed in getting the results you might hope to attain. It’s all up to what you do with the tools you are given! Read more about voice feminization training.
