Personal experiment

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.

About the creator

Selora is a project by Sebastián Vergara Gac, a Product Designer based in Porto. It's a personal experiment exploring how to make pronunciation practice feel clear and friendly — built gradually, honestly, and in the open.

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.
