Ngizim Speech‑to‑Text: Bridging the Digital Divide for a Minority Language

Ngizim is a Chadic language spoken by around 80,000 people in Yobe State, northeastern Nigeria. It belongs to the West‑Chadic branch of the Afro‑Asiatic family and is closely related to other languages like Bade and Duwai. Despite its relatively small speaker population, Ngizim holds immense cultural significance and is used in daily life, traditional ceremonies, and local media. However, like many minority languages, it lacks digital tools for transcription and subtitling. Accurate speech‑to‑text for Ngizim can help preserve the language, improve accessibility, and empower its speakers.

Why Accurate Speech‑to‑Text Matters for Ngizim

• Preservation of oral traditions: Ngizim has a rich oral culture, including folk tales, proverbs, and songs. Transcribing these recordings ensures they are not lost.
• Educational resources: Teachers can create subtitled videos for Ngizim literacy classes, helping students learn to read and write in their mother tongue.
• Local media: Community radio stations broadcasting in Ngizim can automatically transcribe their programs, making them searchable and accessible.
• Language documentation: Linguists and anthropologists can speed up their work by using AI transcription for field recordings.

Specific Transcription Challenges for Ngizim

Ngizim presents several unique challenges for automatic speech recognition (ASR):

• Tonal system: The language uses three tones (high, mid, low) that differentiate meaning. For example, 'kà' (low tone) means 'to go', while 'ká' (high tone) means 'to come'. Speechyou's AI is trained on tonal data to accurately capture these distinctions.
• Limited data: As a minority language, Ngizim has very few existing audio‑text pairs. Speechyou uses transfer learning and data augmentation techniques to build a robust model.
• Non‑standard orthography: The Latin script used for Ngizim is not fully standardized, with variations in spelling of vowels and consonants. The system handles these variations flexibly.

Use Cases in Detail

Oral History Preservation

Elders in Ngizim communities hold invaluable knowledge about history, medicine, and traditions. By recording their speech and using Speechyou to transcribe it, families and researchers can create permanent written records. The transcripts can be stored in digital archives and shared with younger generations who may not understand the spoken language as well.

Subtitle Generation for Videos

Ngizim speakers create videos for cultural events, religious sermons, and local news. With Speechyou, they can generate SRT and VTT subtitle files in Ngizim, making the content accessible to deaf or hard‑of‑hearing viewers. Subtitles also help learners follow along and improve their literacy.
