Loeko
Speech-first Yoruba learning that scores your tones.
Yoruba is tonal, so a learning app that only reads and writes teaches the wrong half of the language. Every Loeko lesson is built around speaking: the app listens, scores pronunciation on tone, fluency and accuracy, gives specific feedback, and repeats the exercise until it is right.
The speech stack is purpose-built for the language rather than borrowed — a Whisper model fine-tuned for Yoruba on the way in, YarnGPT on the way out.
How it is built
- Pronunciation scored on tone as a first-class dimension, not just word accuracy.
- Whisper speech-to-text fine-tuned for Yoruba rather than used off the shelf.
- YarnGPT text-to-speech for native-quality Yoruba output.
- Exercises repeat to mastery instead of advancing on a single pass.
