Yoruba Speech to Text: Preserving Tones, Expanding Reach

Yoruba (Yorùbá) is a Niger‑Congo language spoken mainly in southwestern Nigeria, with communities in Benin and Togo, as well as diaspora populations worldwide. With over 40 million speakers, it is one of the most widely used African languages in media, literature, and everyday life. Accurate speech‑to‑text for Yoruba is not just a convenience; it is essential for preserving the language's rich oral traditions, enabling digital access for learners, and expanding the reach of Yoruba content.

The Challenge of Tones

Yoruba is a tonal language with three level tones: high (´), mid (¯), and low (`). These tones are phonemic, meaning they change the meaning of a word. For example:

• ọkọ̀ (vehicle) vs. ọkọ (spear) vs. ọ̀kọ̀ (husband)
• igbá (calabash) vs. igba (two hundred)

Generic speech‑to‑text engines often flatten these tones, producing garbled text. Speechyou's Yoruba model uses a tonal‑aware architecture trained on thousands of hours of labeled speech. It recognizes tone patterns in context, achieving over 95% accuracy on standard Yoruba.

Dialects & Variations

Yoruba has several major dialects, including Standard Yoruba (based on Oyo), Ekiti, Ijebu, and Ondo. These differ in vocabulary, vowel harmony, and intonation. Speechyou allows users to select from multiple dialect profiles, so if you're transcribing an Ijebu podcast, you can switch to the Ijebu model for better results. This flexibility is crucial for preserving local flavors in transcription.
