Nawdm Speech to Text: Bridging the Digital Gap for a Tonal Language

Nawdm (also spelled Nawdam) is a Gur language spoken primarily in the Plateaux Region of Togo, with smaller communities in Ghana. With an estimated 200,000 speakers, it is an important language for local communication, culture, and identity. Like many minority languages, Nawdm has limited digital presence, which makes accurate speech recognition a challenge. However, the need for transcription and subtitling in Nawdm is growing, especially for community media, language documentation, and educational projects.

Why Accurate Nawdm Transcription Matters

Transcribing Nawdm audio is not just about converting speech to text; it is about preserving oral traditions, making information accessible, and empowering speakers. For example, local radio stations broadcast in Nawdm to reach rural audiences, but without transcripts, these broadcasts are not searchable or easily archived. Similarly, educators creating Nawdm-language content for schools need subtitles to support literacy. Speechyou's Nawdm speech-to-text solution addresses these needs with high accuracy.

Challenges in Transcribing Nawdm

Nawdm presents several challenges for automatic speech recognition:

• Tonal system: Nawdm uses three level tones (high, mid, low) that are phonemic. A word like 'kpa' can mean 'to cut', 'to chew', or 'to hit' depending on tone. Generic ASR systems often ignore tone, leading to errors.
• Limited training data: As a low-resource language, there are few publicly available transcribed speech datasets for Nawdm. Speechyou uses transfer learning to bootstrap the model.
• Dialectal variation: Differences across Central, Northern, and Southern Nawdm affect vowel quality and vocabulary. Speechyou's model is trained on multiple dialects to reduce bias.

Use Cases for Nawdm Speech to Text

• Oral history preservation: Transcribe interviews with elders to document traditional knowledge and stories.
• Podcast and radio transcription: Convert Nawdm-language audio content into text for searchability and subtitles.
• Educational subtitles: Generate SRT files for Nawdm instructional videos, helping students read along.
• Community announcements: Transcribe public health messages or local news for wider distribution.
• Language research: Provide linguists with accurate transcriptions for analysis of Nawdm phonology and grammar.
• Accessibility: Make Nawdm video content accessible to deaf and hard-of-hearing community members who read Nawdm.
