Dagbani Speech-to-Text: Bringing Ghana's Northern Voice to Digital Life

Dagbani (Dagbanli) is a Gur language spoken by approximately 3 million people, primarily in the Northern Region of Ghana. It serves as a trade language and a marker of identity for the Dagomba people. Despite its significance, Dagbani has been underserved by speech technology. With Speechyou, that changes. Our AI-powered tool provides accurate speech-to-text, transcription, and subtitle generation for Dagbani in the Latin script.

Why Accurate Dagbani Transcription Matters

From preserving oral epics told by elders to creating subtitles for local-language YouTube channels, transcription unlocks new possibilities. Researchers can transcribe interviews for sociolinguistic studies. NGOs can add subtitles to health awareness videos. Podcasters can provide searchable transcripts. Without reliable ASR, these tasks require manual effort or go undone.

Special Challenges for Dagbani ASR

Dagbani presents several challenges for automatic speech recognition:

• Tones: Two lexical tones (high and low) distinguish words. For instance, /tí/ (high) means 'to give', while /tì/ (low) means 'to push'. Tone errors can change meaning entirely.
• Vowel harmony: Within a word, vowels must belong to the same harmonic set (e.g., /i e ə a o u/ contrast with /ɪ ɛ ʌ/). Our model respects this.
• Limited training data: Unlike English or French, Dagbani has few publicly available transcribed speech corpora. Speechyou uses transfer learning from related languages and fine-tuning on curated Dagbani data.
• Dialectal variation: The Nayuli, Nanun, and Tomo dialects differ in pronunciation and lexicon. Our system handles multiple varieties.

Use Cases for Dagbani Speech-to-Text

• Oral History Preservation: Record and transcribe stories from elders, creating searchable archives for future generations.
• Local Radio and Podcasts: Convert Dagbani broadcasts into text for show notes, quotes, and multilingual subtitles.

• Agriculture: Transcribe farming tips shared on community radio, making them accessible in text format.
• Healthcare: Create subtitles for health campaigns in rural areas, ensuring accurate communication.
• Social Media: Add Dagbani subtitles to videos on Facebook, TikTok, and YouTube to engage the Dagbani-speaking diaspora.
