Ika Speech to Text: Transcribing the Language of the Ika People

Ika is a language spoken primarily in Delta State, Nigeria, by the Ika people. It belongs to the Igbo subgroup of the Niger-Congo language family and is estimated to have around two million native speakers. The language is written in the Latin script, and while it shares some mutual intelligibility with other Igbo varieties, it has its own distinct phonology, vocabulary, and tonal system. In the digital age, having accurate speech-to-text capabilities for Ika is crucial for preserving the language, promoting literacy, and enabling content creation.

The Importance of Speech-to-Text for Ika

Many Ika speakers consume media in English or other major languages due to a lack of tools that support their native tongue. By providing Ika speech-to-text, we empower local creators, educators, and institutions to produce content in Ika. This strengthens the language's presence in the digital space and helps prevent language shift. Accurate transcription also supports language documentation and revitalization efforts.

Challenges in Transcribing Ika

• Tonal complexity: Ika is a tonal language with three tones (high, mid, low). Tone is phonemic, meaning it changes word meaning. For example, "akwa” (high-high) can mean "bridge,” while "akwa” (low-low) means "cry." Standard ASR systems often fail to capture these distinctions.
• Limited data: As a low-resource language, there are few publicly available speech datasets for Ika. This makes it difficult for generic ASR models to achieve high accuracy.
• Dialectal diversity: The major dialects—Agbor, Owa, and Umunede—differ in pronunciation and lexicon. A model trained on one dialect may not perform well on others.
• Nasal vowels: Ika has nasalized vowels (e.g., /ã/, /ẽ/) which are not present in English and are often misrecognized by multilingual models.

How Speechyou Solves These Challenges

Speechyou's AI model for Ika is built to handle these challenges head-on. It uses a custom acoustic model trained on Ika speech data that includes tonal annotation and dialectal variation. The system employs a transformer-based architecture that learns to map sound to text while accounting for tone through pitch features. For dialectal variation, the model is trained on a balanced corpus from multiple dialects, and users can optionally select a dialect preset for fine-tuning. The result is a transcription accuracy of over 95% on clear audio, a significant improvement over generic tools.
