What Harmonious does
Harmonious is a voice-training studio for trans and non-binary people who want to work on how their voice sounds and feels. It measures a short recording, shows the results in plain language, and turns them into practice you can do between check-ins.
Practise
Goal-based exercises, reading passages and a practice log that follows your own targets rather than a single “ideal” voice.
Review
Progress charts that show what changed over time, and PDF reports on Hosted. Use any name that feels like yours; no legal name is required.
Private by default
Hosted recordings and results live on this server, not in an advertising or analytics cloud. There is no telemetry and no built-in AI chat. The operator of this server can access stored data; account separation is enforced by the application, not end-to-end encryption. Read the privacy policy.
