Accessibility Statement

VoiceRangeTest.com is committed to making its tools and educational content accessible to the widest possible range of users, including people with disabilities.

This statement explains our current accessibility status, the known limitations of our tools for certain users, what we have implemented to support accessibility, and how to contact us if you encounter a barrier.

Our Commitment

We believe that anyone curious about the science of voice, pitch, frequency, or music deserves access to tools and information that help them explore it — regardless of disability, device, or technical setup.

VoiceRangeTest.com aims to conform to the Web Content Accessibility Guidelines (WCAG) 2.1 at Level AA — the internationally recognised standard for web accessibility published by the World Wide Web Consortium (W3C). These guidelines define how to make web content more accessible to people with visual, auditory, motor, cognitive, and speech-related disabilities.

Accessibility is an ongoing commitment, not a one-time declaration. When barriers are identified — through our own review or through user feedback — we work to address them.

Current Accessibility Status

VoiceRangeTest.com is partially conformant with WCAG 2.1 Level AA. Partially conformant means that some parts of the website do not yet fully meet the standard. Known gaps are disclosed in the Limitations section below.

What we have implemented

Keyboard navigation. Core site navigation — menus, links, and page structure — is accessible via keyboard. Users who cannot use a mouse can navigate between sections using the Tab key and activate links with Enter.

Text readability. Body text is set at a minimum of 16px with sufficient line spacing to support readability for users with dyslexia or low vision. Heading levels (H1, H2, H3) follow correct hierarchical order throughout the site, allowing screen readers to navigate content structure logically.

Colour contrast. Text and background colour combinations across the site are chosen to meet or exceed the WCAG 2.1 Level AA minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text.

Descriptive link text. Links across the site describe their destination — not generic phrases such as “click here” or “read more.” This benefits screen reader users who navigate by cycling through links.

Alt text on images. Meaningful images include descriptive alt text. Decorative images use empty alt attributes so screen readers skip them appropriately.

Responsive design. The site adapts to screen sizes from small mobile devices to large desktop monitors. Content reflows cleanly without horizontal scrolling at standard zoom levels up to 200%.

No auto-playing media. No audio or video begins playing automatically without user action.

Page titles. Every page has a unique, descriptive title tag, allowing users navigating between browser tabs or using a screen reader to identify their location.

Skip navigation link. A “Skip to content” link is available at the top of every page, allowing keyboard and screen reader users to bypass navigation and reach page content directly.

Known Limitations by Tool Category

VoiceRangeTest.com has 20 tools across three categories with different accessibility profiles. Each is addressed separately.

Category 1 — Voice and Microphone Input Tools

This covers the Voice Range Test, Vocal Range Calculator, Voice Type Test, Deep Voice Test, Pitch Accuracy Test, Pitch Detector, Note Identifier, Frequency Finder, Sound Decibel Meter, Vibrato Analyzer, Perfect Pitch Test, and Microphone Test.

Voice production dependency. Tools that measure vocal pitch — including the Voice Range Test, Vocal Range Calculator, Pitch Detector, Pitch Accuracy Test, Deep Voice Test, and Vibrato Analyzer — require the ability to produce sustained vocal sound and access to a functioning microphone. These tools are not usable by people who are unable to vocalise or who do not have a microphone available. This is an inherent constraint of the tool’s purpose, not a design oversight.

Real-time display accessibility. During active voice testing, the pitch detector displays note names, frequency readings, and tuning indicators in real time. These rapidly updating values are not currently announced by screen readers, as frequent live announcements during active vocalisation would interfere with the testing process. The final result summary is the accessible output for screen reader users.

Microphone permission prompts. The browser microphone permission prompt is a native browser UI element and is not under this site’s control. Its accessibility depends on the browser being used. Chrome and Firefox provide accessible permission prompts with keyboard navigation.

Category 2 — Audio Output and Frequency Tools

This covers the Tone Generator, Audio Frequency Test, Ear Training Test, Interval Ear Training, Online Metronome, and Vocal Warm-Up Generator.

Hearing dependency. The Tone Generator, Audio Frequency Test, Ear Training Test, Interval Ear Training, and Online Metronome produce audio output that is central to their function. These tools are not usable in their current form by users who are deaf or have severe hearing impairment. The Tone Generator’s frequency slider and waveform selector can be operated by keyboard, but the output itself is audio only.

Audio Frequency Test limitation. The hearing range test measures which frequencies you can hear. By its nature, this test is inaccessible to users with significant hearing impairment — it cannot measure what cannot be heard.

Metronome visual indicator. The Online Metronome includes a visual beat indicator alongside the audio click, making it partially usable for users with hearing impairment who can use the visual reference. However, the primary use case (tempo reference for music practice) remains audio-dependent.

Ear training result feedback. Correct and incorrect answer feedback in the Ear Training and Interval Ear Training tools is currently delivered both visually and as audio tones. The visual feedback component is accessible to screen readers. We are working to improve ARIA labelling for result announcement consistency.

Category 3 — Music Theory Tools

This covers the Song Key Finder, Vocal Scale Finder, and Vocal Warm-Up Generator (non-audio functions).

Fully keyboard accessible. The Song Key Finder and Vocal Scale Finder are text input and results-based tools that operate without audio input or output. Both are fully navigable by keyboard and compatible with screen readers. Input fields have associated labels and results are displayed as structured text.

Vocal Warm-Up Generator. The warm-up exercise sequence displays text-based instructions. The tool is accessible to screen reader and keyboard users for the text content. Any audio playback components follow the audio output accessibility notes in Category 2 above.

General Interface Limitations

Slider controls. Range input sliders used across the tools — including the Tone Generator frequency slider and volume controls — can be operated with keyboard arrow keys. ARIA labels are present on most sliders. We are reviewing ARIA live region announcements for slider value feedback to improve screen reader reporting of current values.

Third-party advertising. This site may display advertisements served by Google AdSense. The accessibility of individual ad creatives is outside our direct control as ads are provided by third-party advertisers.

Text Alternatives for Tool Results

We recognise that several tools are not accessible to users with voice or hearing limitations. The following text-based educational pages cover the knowledge the tools are built around and are fully accessible without audio interaction:

These pages are designed to be fully usable with screen readers and keyboard navigation.

Assistive Technology Compatibility

VoiceRangeTest.com has been tested for basic compatibility with the following assistive technologies:

  • Screen readers: NVDA with Chrome (Windows), VoiceOver with Safari (macOS and iOS)
  • Keyboard-only navigation: Tested in Chrome and Firefox on Windows
  • Browser zoom: Content tested at 200% zoom without loss of content or functionality
  • High contrast mode: Core content remains readable in Windows High Contrast mode

We recommend using an up-to-date version of Chrome or Firefox with your preferred assistive technology for the most consistent experience.

Feedback and Contact

We welcome accessibility feedback. If you experience a barrier on any page or tool — a control that cannot be used without a mouse, a result not announced by your screen reader, or any other accessibility issue — please let us know.

Contact: voicerangetest.com/contact-us

Please include:

  • The page or tool where you experienced the issue
  • The assistive technology and browser you were using
  • A description of what you expected and what happened instead

Formal Complaints

If you are not satisfied with our response to an accessibility concern, you may contact the relevant national enforcement body for accessibility standards in your country. In the United Kingdom, this is the Equality and Human Rights Commission. In the United States, the relevant body depends on the context of the accessibility complaint.

Review Schedule

This accessibility statement is reviewed and updated at least once per year, or whenever significant changes are made to the site’s tools or structure.
