Dogoso Speech to Text: Preserving a Language with AI

Dogoso is a Gur language spoken by around 9,000 people in the Comoé Province of Burkina Faso. It is a language rich in oral tradition, with stories, songs, and proverbs that have been passed down for centuries. However, like many minority languages, Dogoso faces pressures from dominant languages such as French and Jula, and its written form is still developing. Automatic speech-to-text offers a way to capture and preserve the spoken word, making it accessible for education, documentation, and media.

Why Accurate Transcription Matters for Dogoso

Accurate speech-to-text for Dogoso is not just a technical challenge; it is a cultural necessity. Transcribing oral histories allows communities to create written records that can be archived, studied, and shared with younger generations who may not speak the language fluently. It also enables the creation of subtitles for videos, making content accessible to the deaf and hard-of-hearing within the community. Furthermore, transcription supports language revitalization efforts by providing materials for literacy programs.

Challenges in Transcribing Dogoso

• Tonal Complexity: Dogoso uses three tones (high, mid, low) to differentiate words. For instance, 'tã' (high) means 'head', while 'tà' (low) means 'to buy'. Standard ASR models often flatten tones, losing meaning.
• Limited Training Data: There are very few publicly available transcribed audio corpora for Dogoso. Most commercial ASR systems do not support the language at all.
• Dialectal Variation: While the language is relatively homogeneous, slight differences in pronunciation and vocabulary exist between villages, requiring adaptable models.
• Code-Switching: Many speakers mix Dogoso with Jula, especially in urban areas. An ASR system must handle multilingual input gracefully.

Speechyou overcomes these challenges by offering a platform where users can train custom models. The AI learns from your audio and text pairs, adapting to the specific dialect, tone patterns, and vocabulary of your recordings.

Use Cases for Dogoso Transcription

1. Oral History Preservation

Elders in Dogoso communities hold a wealth of knowledge about local customs, medicinal plants, and history. By transcribing their spoken stories, communities can create permanent digital archives that are searchable and translatable.

2. Community Radio and Media

Radio is a primary source of information in rural Burkina Faso. Transcribing broadcasts in Dogoso allows for the production of written news summaries, subtitles for video clips shared on social media, and scripts for educational programs.

3. Language Documentation and Research

Linguists working on Gur languages can use Speechyou to automatically transcribe field recordings, saving hundreds of hours of manual work. The output can be exported as plain text or with timestamps for analysis.

4. Bilingual Education

In schools where Dogoso is used alongside French, teachers can generate reading materials from spoken lessons. This supports literacy in both languages and helps students connect oral and written forms.

5. Accessibility for the Deaf

Subtitling videos in Dogoso makes content accessible to deaf community members who read the language. This is crucial for public health announcements, religious services, and cultural events.

6. Healthcare Communication

Health workers often record audio messages in Dogoso to share information about vaccinations, hygiene, and disease prevention. Transcribing these messages ensures they can be distributed in written form to clinics and households.
