Private voice training
Work with pitch, resonance and ease in a studio that belongs to you. Record a short check-in, see what your voice is doing, and follow a practice plan built from your own measurements. Analysis stays on your instance, with no telemetry and no ads. Self-host it today, or join the waitlist for hosted access.
How it works
Harmonious is not a course you follow blindly. It listens to where your voice is now, then gives you something specific to practise.
All five steps happen inside your own instance.
Twenty to thirty seconds of comfortable speech — read the passage or talk naturally. A check-in is a snapshot, not a performance.
Pitch, resonance, loudness and voice quality are measured on your machine or your own server. Audio is not sent to us.
Your measurements are turned into a practice plan by fixed rules. The same reading produces the same plan, so you can see why each exercise was chosen.
Trends across check-ins show direction, not a scoreboard. Export a PDF report to keep for yourself or bring to a session.
Identity-aware targets, including transmasculine and non-binary custom targets, so the direction is yours to set.
Pricing
A license is for one person. Paid licenses are bought through a crypto checkout. Hosted access is not on sale yet; the waitlist is free.

One person, your own installation. The full app with analysis, practice plans and PDF reports.
Self-hosted license. Does not include hosted storage.
Supporter
$39one-time
Everything in self-hosted, with a longer runway of updates and support that puts free licenses in other hands.
One-time. One person. Self-hosted. Arranged manually during launch so the checkout charges the right amount.
Hosted access
Waitlist
A hosted account on a server we run, with the same studio and reports. Not on sale yet, and no payment is taken to join.
Free to join. No payment is taken now.
Good to know. $20 is a self-hosted license for one person: 12 months of updates and support. It is not a subscription, and it does not include hosted storage or updates beyond 12 months.
Sliding scale. Free licenses are available for people who need one. Write to support@harmonious.science to ask.
Privacy & security
Your voice is sensitive. Harmonious keeps the default close to you, and says plainly where a hosted server changes that.
No analytics, tracking pixels, advertising or third-party embeds. Nothing is reported back to us when you practise.
Audio and results live on the instance you use: your machine for a self-hosted install, or the server for a hosted account. They are not sent to a Harmonious cloud.
On a hosted instance, the operator controls the server and can access stored data. Accounts are separated by the app; it is not end-to-end encryption.
License verification happens on your instance without a call home. You can work without a network connection.
Payments are visible on-chain and irreversible. Amount and timing can be seen by anyone. We never collect card details.
Harmonious supports practice. It does not diagnose, treat or prevent any condition, and it is not a substitute for a clinician or speech professional.
It records a 20–30 second voice check-in, measures pitch, resonance, loudness and voice quality on your own instance, then turns the results into practice and progress reports.
$20 covers one person on a self-hosted install, with 12 months of updates and email or community support. $39 extends updates to 2 years, adds priority support and funds free licenses. Neither includes hosted storage or lifetime updates.
Payment processors can decline this kind of product, and card data is another thing to protect. Crypto avoids both. The trade-off is that payments are public on-chain and cannot be reversed.
Completed crypto payments cannot be reversed, so we cannot refund them to your wallet. If a license does not work, write to support@harmonious.science and we will help.
A computer you control, a modern browser and a microphone. The app runs on your computer and opens in the browser; setup instructions come with the license.
Each install has its own local accounts. Recordings, check-ins and practice history live in that instance’s data folder — on your machine if self-hosted, on the operator’s server if hosted. On a hosted server the operator can access stored data.
No. It is a training tool, not a medical device. It does not diagnose or treat any condition, and it is not a substitute for a clinician or speech professional.
No promise. Passing is not something software can guarantee, and Harmonious does not claim to. It gives you measurements and practice; how your voice changes is individual.
