Izon Speech to Text: Preserving a Language of the Niger Delta

Izon (also known as Ijaw) is a Benue-Congo language spoken primarily in the Niger Delta region of Nigeria. With an estimated 1 million speakers, it is one of the most widely spoken indigenous languages in the coastal south. However, like many African languages, it has limited digital resources. Accurate speech-to-text tools for Izon have been virtually nonexistent — until now.

Why Accurate Izon Transcription Matters

Izon is a language of rich oral tradition. Proverbs, folktales, and genealogies are passed down verbally. But as younger generations shift to English and Nigerian Pidgin, these oral histories are at risk. Transcribing spoken Izon into written text helps preserve them for future study and education. Moreover, local radio stations, churches, and community health workers all communicate in Izon, and having written records improves documentation and accountability.

Transcription Challenges Specific to Izon

Izon presents several hurdles for automatic speech recognition:

• Tones: Izon is a tonal language with two level tones (high and low) and a falling tone. "Bé" (to come) and "bè" (to cut) are distinguished only by tone. Most ASR models ignore tone, leading to errors.
• Nasal vowels: Vowels can be nasalized, as in "kɔ̃" (to flow). The orthography sometimes marks this with a tilde or an 'n' after the vowel, but not consistently.
• Dialect diversity: There are at least four major dialect groups, with significant lexical and phonological differences. A single model may fail on a different dialect.
• Limited training data: Izon is not included in major speech recognition corpora, so generic ASR engines cannot handle it at all.

Speechyou addresses each of these challenges through dedicated Izon models trained on field recordings and native speaker data, with separate profiles for the main dialects.
