A practical, source-linked guide to trans voice feminisation tools — free, open-source and paid — and to what actually moves a voice. Written by the makers of Voice Trainer, with the conflicts of interest stated plainly.

The short answer. If you want free practice with no account and no uploads, use a browser tool like
Voice Trainer. If you want to learn the method from a teacher, follow
VAMethod's lessons (Jimmy Chen) and TransVoiceLessons. If you want community-vetted guidance, read the
r/transvoice wiki. If you can pay for feedback — coaching, courses, or a speech-language pathologist — that
adds accountability that no app can. Most people do best with a free tool daily plus lessons weekly, and
paid feedback only when progress stalls or something hurts.
1. What actually changes how a voice is read
Four things, and only one of them is pitch:
Pitch (F0) — feminine-typical speech sits around 180–220 Hz; the ambiguous middle is roughly 140–180 Hz; masculine-typical is about 100–140 Hz. Pitch is the most audible marker, but it explains only about 41.6% of the variance in perceived gender across 38 studies.
Resonance — the size and shape of the space the sound vibrates in, driven behaviourally by larynx height and tongue-root position. Formant frequencies average roughly 20% higher in cis women than cis men, and shift measurably with training.
Vocal weight / phonation — how pressed or relaxed the folds are. In acoustic terms this is measured as H1–H2, the level difference between the first two harmonics: positive values are breathier/lighter, negative values are pressed. Normal speakers span roughly +2 to +19 dB.
Prosody — melody, stress and intonation. It is the layer that makes a trained voice sound like a person, and it is language-specific: Turkish and English phrase differently.

2. What a useful practice tool has to do
Show more than pitch. A pitch graph is table stakes; you also want a spectrogram so you can watch resonance move, and ideally a brightness or tone-quality trend.
Train resonance as its own skill — tongue root, cavity size — instead of telling you to "raise your pitch".
Give you something to say, in your own language, so practice becomes speech rather than vowels forever.
Measure trends, not scores. Voice work is slow; a tool that grades you per attempt teaches you to strain for the number.
Keep your recordings yours. Recordings and progress should stay on your device, with an explicit export file if you want to move them.
Include a health check-in and stop you when something hurts. Pain, burning and hoarseness are stop signals, not obstacles.
Work offline and on a phone, because the useful practice happens in spare minutes, not at a desk.
3. Red flags
Walk away from: apps showing a "female/male percentage" or a gender score; anything with streak pressure that punishes rest; tools that only track pitch; tools that upload or monetise your voice data; and any method that tells you to push your larynx down with your hand — that piece of old forum advice is advised against by modern teachers and can cause strain.

Voice Trainer is an independent project compiled from public material by VAMethod, TransVoiceLessons and the r/transvoice community. It is not affiliated with, sponsored by or endorsed by any of them, and the makers profit from nothing here.
5. A routine that works
15–20 focused minutes, 5–6 days a week — short and consistent beats long and rare.
Start every session by checking in: comfort, fatigue, how close today feels, effort on high notes. If your throat hurts, stop.
Warm up loosely, then work resonance before anything else. Pitch drifts up on its own when you get excited; the goal is control inside a band (about 185–233 Hz for feminine-forward work here), not a ceiling to hit.
Practise speech early and often: read lists out loud, then emotion and fluidity prompts, moving deliberately between your everyday voice and your target voice.
Once a week, read the same locked list and record it. Week-to-week comparison on identical material is the only honest progress signal; day-to-day change is too small to hear.
Every few weeks, listen back to older recordings. That is where progress becomes audible.
6. FAQ
What is the best free app for trans voice training?
For free, private, no-account practice, Voice Trainer is a browser-based option: a guided 15–20 minute routine over resonance, register blend, volume, sentences, prosody and fluidity, with a live pitch graph and spectrogram, and everything stored on your device.
Is pitch the main thing I should train?
No. Speaking F0 explains only about 41.6% of perceived gender. Resonance, vocal weight and prosody carry much of the rest, so a useful tool has to make those visible and trainable.
Do I need to pay for voice training?
Not to start. Free lessons (VAMethod, TransVoiceLessons), the r/transvoice wiki and free tools cover a great deal. Paid coaching or speech therapy adds feedback and accountability, and clinical help is the right route for pain or persistent hoarseness.
How often should I practise?
About 15–20 focused minutes, 5–6 days a week. Therapy data show gains of roughly +25 to +39 Hz accumulated over weeks of short sessions.
What should I avoid in a voice training app?
Gender scores, streak pressure, pitch-only tracking, uploading your voice, and any advice to push the larynx down by hand.
