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

1

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.

2

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.

3

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.

4

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.

Begin Your Pronunciation Journey

Start with the interactive IPA chart if you want to understand the sound system, or the pronunciation checker if you want feedback on a specific word.
