About PronunciationChecker
Helping English learners master pronunciation across the globe
Our Vision & Mission
PronunciationChecker is a free set of tools and guides for practising English pronunciation. It combines interactive phonetics references, browser-based speech feedback and written explanations grounded in published phonetics research, aimed at learners who want to work on specific sounds rather than general fluency.
The goal is intelligibility rather than sounding native: being understood without effort in study, work and everyday conversation. That is a realistic target for adult learners, and it is what most of the material here is organised around.
Our Foundation & Leadership
PronunciationChecker was built and is run by Eriberto Nascimento, a software developer with a long-standing interest in phonetics and second-language learning. The site started as a personal project: a set of tools to practise English pronunciation with immediate feedback, built because the existing free options were either too limited or locked behind a subscription.
Everything here is written and maintained by one person. The articles draw on published work in phonetics and second-language speech research, and the tools use the speech recognition and synthesis built into modern browsers, which is why they run without an account and without sending your voice to a server. If you spot an error in a transcription or an explanation, please get in touch — corrections are genuinely welcome. How articles are sourced, reviewed and corrected, and how advertising is kept separate from them, is set out in our editorial policy.
Foundational Principles & Commitments
Universal Accessibility
Every tool and article on this site is free to use, with no account required. That is not a promotional claim — it is simply how the site is set up, and the intention is to keep it that way.
Linguistic Precision
Transcriptions use the International Phonetic Alphabet and follow standard reference dictionaries. Where British and American pronunciations differ, both are given rather than one being presented as correct.
Evidence-Based Iteration
Articles are updated when the explanation turns out to be wrong or unclear. Reader corrections are the main source of those revisions, so if something here does not match what you have been taught, please say so.
User-Centric Innovation
Tools are built to do one thing and give a clear result, rather than to maximise time on the page. Several deliberately tell you when a result is unreliable instead of showing a confident score.
Why PronunciationChecker Distinguishes Itself
- ✓ Scientifically-Grounded Methodology: Explanations follow established work in phonetics and second-language speech perception, including research on perceptual training and intelligibility.
- ✓ Multi-Accent Coverage: American and British pronunciations are given side by side, with the systematic differences explained rather than listed word by word.
- ✓ Institutional-Grade Resources: The written guides go into the articulatory detail usually found only in phonetics textbooks or one-to-one lessons.
- ✓ Scalable Technology Infrastructure: The speech tools run entirely in your browser, so nothing you record is uploaded or stored.
- ✓ Commitment to Transparency: Where a tool has real limits — and automatic speech scoring has several — those limits are stated on the page rather than hidden.
