About Selora

Selora is a tool for practicing pronunciation: Spanish if you speak English, English if you speak Spanish. You listen to a reference, see the syllable-by-syllable breakdown, and practice with your own voice.

How it's built

Under the hood, Selora runs on voice AI: speech synthesis generates the reference audio, and pronunciation-recognition models analyze your voice syllable by syllable. The goal is to turn that into useful, instant feedback without getting in the way of the experience.

Each word gets its own server-rendered page with its phonetic transcription and syllable breakdown. When you record, your voice is captured and processed in the browser, compared against a native reference, and turned into a per-syllable score shown as a three-color traffic light. The priority is keeping the technology out of the way, so practicing feels simple.

Word definitions come from Wiktionary, trimmed to fit here and translated where needed. They're used and shared under the CC BY-SA 4.0 license. Reference audio and voice analysis are generated by Azure Speech.

Frequently asked questions

Is there a free tool that scores my pronunciation?

Selora does it at no cost today: you record your voice, it compares you against a native reference and gives you a score for every syllable. It runs in the browser, with nothing to install.

Do I need an account to try it?

Not to start. Without an account you can do the daily session, look up any word and take the three-minute test. An account is only needed for what gets saved: your streak, your phrases and the words you struggle with.

Can I find out which sounds I get wrong?

Yes, that is what the test does: you say six lines and it points out the sounds that give you away, and whatever you miss comes back in your reinforcement over the following days.

How is it different from a pronunciation dictionary?

A dictionary lets you hear how a word sounds, but it does not listen to you. Selora scores your recording and tells you which syllable slipped, which is the part you cannot judge on your own.

How does it decide whether I said it right?

It compares your recording against a neural voice using Azure Speech pronunciation assessment. Every line has its own ceiling measured with that same voice, so you are not punished for words the reference itself scores badly.

Does it work for learning Spanish too?

Yes. Selora runs both ways: English for Spanish speakers, and Spanish for English speakers, with its own content on each side.
