Marma Speech to Text: Preserving a Minority Language Through AI Transcription

Marma (मार्मा) is a Tibeto-Burman language spoken by the Marma people, an indigenous community of about 200,000 living mostly in the Chittagong Hill Tracts of Bangladesh and neighbouring regions of Myanmar. As a minority language surrounded by Bengali and Burmese, Marma faces pressures of language shift and attrition. Technology that supports the language in written form — especially in the Devanagari script — can help revitalise Marma and ensure its survival in the digital age.

Why Accurate Speech-to-Text for Marma Matters

For a tonal minority language like Marma, having a reliable speech-to-text tool means more than convenience: it is a gateway to digital inclusion. Marma speakers can now create written content from spoken word without needing to type in Devanagari. This opens up opportunities for:

• Preserving oral traditions such as folk tales, songs, and rituals.
• Creating subtitles for local videos on YouTube and Facebook.
• Assisting linguists in documenting dialectal variation.
• Enabling hearing-impaired community members to access Marma media.

Specific Challenges in Transcribing Marma

Transcribing Marma with AI is not straightforward. The greatest difficulty is its tonal system. Unlike English, where tone affects emotion rather than meaning, in Marma a high tone versus a low tone can change the word entirely. Many speech recognition engines treat tone as noise and filter it out, causing errors. Speechyou’s ASR is built to recognise and preserve tonal information, outputting the correct Devanagari spelling for each tonal variant.

Another challenge is script adaptation. Devanagari is standard for Hindi, Marathi, and other Indo-Aryan languages, but Marma phonology includes sounds foreign to those languages — such as the voiceless nasals /n̥/ and /m̥/. Speechyou uses a custom extended Devanagari mapping to represent these sounds transparently, avoiding confusion for readers.

Dialectal diversity also complicates transcription. The Kyauktaw dialect pronounces certain consonants more softly than the Standard dialect, while the Paletwa dialect has shifted vowel qualities. Speechyou’s model is trained on a dialect-balanced corpus and allows users to specify the dialect for improved accuracy.

Practical Use Cases for Marma Transcription

Community Media: Local Marma radio stations and podcasters can automatically transcribe their shows, creating searchable archives. SRT subtitles can be generated for video content, making it accessible to Marma youth who may be more comfortable reading than listening.

Educational Content: Teachers in hill-tract schools can narrate lessons in Marma and generate Devanagari transcripts for handouts. Students can revise using text that matches their spoken language.

Linguistic Research: Field linguists recording Marma speakers can get near-instant transcriptions, freeing up hours of manual work. The exported text can be imported into software like ELAN for annotation.

Oral History Preservation: NGOs working in the Chittagong Hill Tracts often collect oral histories from Marma elders. Speechyou converts these recordings to text, preserving stories for future generations even after the spoken word fades.
