Summary: We want the guides and tools to work for as many people as possible. Our target is WCAG 2.2 Level AA, but the site has not had a full accessibility audit, so we do not claim conformance. Some tools depend on a microphone or on hearing, and we say plainly where that creates limits.
Our target
The target is the Web Content Accessibility Guidelines (WCAG) 2.2, Level AA, published by the W3C. No independent WCAG evaluation or formal screen-reader test has been done yet, so this is a goal, not a claim that every page meets every success criterion.
What we do today
- Pages use a logical heading order and descriptive link text.
- Tool results are shown as text and numbers (note name, hertz, cents, range), not only as meters or colours.
- In the main tools, colour is not the only signal: tuning and match results are also given in words and numbers.
- The main tool layouts were tested at phone widths of 360 to 390 pixels.
- The main tools use standard HTML buttons, menus and labelled form fields, and their result areas are marked as live regions so a screen reader can announce the result.
Tools that work without a microphone
Several tools give you a way around microphone input:
- The Voice Range Test lets you enter your lowest and highest notes by hand.
- The Vocal Range Calculator works entirely from notes you type or select.
- The Vocal Range Chart is drawn on the server with a text title and description, works without JavaScript, and lists every range as text below the chart.
- Written references such as vocal range notes and types of vocal ranges carry the same information as text.
Microphone tools
The Pitch Detector, Note Identifier, Voice Hz Test, Voice Type Test and Pitch Accuracy Test need live sound. They can be hard to use if you cannot produce voice input, cannot grant microphone permission, or use assistive technology that struggles with fast-changing results. The Note Identifier can also read an audio file you choose, which helps if live singing is difficult. Microphone audio stays in your browser; see the privacy policy.
Listening exercises
The Interval Ear Training, Tone Generator and Audio Frequency Test are about hearing sound, so they have no meaningful non-audio version. They are practice exercises, not hearing tests. The Online Metronome shows each beat as a dot as well as playing a click.
Live results and screen readers
Pitch readings change many times per second. Announcing every change would overwhelm a screen reader, so the tools show a stable summary (lowest and highest note, final result or score) when a test finishes. Making live results easier to follow with assistive technology is ongoing work.
Browsers and devices
The tools need a current browser with the Web Audio API, which includes recent versions of Chrome, Edge, Safari and Firefox. Automated tests for the main tools ran in Microsoft Edge on desktop and phone-sized screens. Safari, Firefox and physical Android phones have not yet been formally tested, so if a tool does not work with your browser or assistive technology, please tell us which one you use. The pages themselves are ordinary WordPress pages and work with browser zoom, reader modes and text-size settings.
Known limitations
- Real-time pitch displays, needles and moving traces are visual; the text values next to them carry the information.
- On phones, the vocal range chart scrolls sideways; a hint says so, and the text legend below lists every range.
- Keyboard and screen-reader behaviour has not been formally tested in every tool.
- Browser permission prompts are controlled by your browser, not by us.
- Ads and the ad consent message are provided by Journey by Mediavine, a third party; their accessibility is outside our direct control, but please report problems with them to us.
This list is not complete. Measurement limits that affect everyone are described in accuracy and limitations, and how tools are checked is in our testing methodology.
Report a barrier or ask for another format
Email contact@voicerangetest.com or use the contact page. It helps to include the page URL, what you were trying to do, what went wrong, and your browser, device or assistive technology if you are happy to share it. You don’t need to tell us about a disability. If you can’t reach information you need, tell us and we will try to provide it another way, for example as plain text by email.
Barriers that block a tool’s core function or a page’s main content are fixed first. Other improvements planned: clearer focus outlines, better labels on older controls, and less motion where it isn’t needed.
Changes to this statement
We update this statement when tools change, when a barrier is fixed or when we complete an audit. Related questions may be answered in the FAQ, and ad cookies and consent are explained in the cookies policy.
