Khamti (Devanagari Script) Speech to Text: Preserving a Tai Language with AI

Khamti is a Tai language spoken by approximately 10,000 people in the border regions of Myanmar and India. In Myanmar, it is found in the Sagaing Region, while in India it is spoken in the Tinsukia district of Assam and the Namsai district of Arunachal Pradesh. The language is part of the Tai-Kadai family, sharing roots with Shan, Thai, and Lao. Khamti is tonal, with three tones that distinguish meaning — for example, the word "ka" can mean "chicken", "to wait", or "to be hard" depending on the tone. Historically written in a script derived from the Burmese alphabet, Khamti in India is now written in Devanagari, the script of Hindi and many other Indic languages. This transition has made it easier for Khamti speakers who are also literate in Hindi, but it also means that the script is not yet fully standardized.

Why Accurate Speech-to-Text Matters for Khamti

As a minority language, Khamti faces the risk of gradual language shift. Younger generations are increasingly fluent in Assamese, Hindi, or Burmese, and the number of fluent speakers is declining. Transcribing oral traditions, including folk tales, songs, and Buddhist chants, is vital for language preservation. Accurate speech-to-text technology can capture these recordings in a searchable, editable text format. Additionally, Khamti communities are producing digital content — local news, cultural videos, and educational materials — but without subtitles, these remain inaccessible to a wider audience. Speechyou’s Khamti speech-to-text tool enables creators to add Devanagari subtitles, making their content more inclusive.

Challenges in Transcribing Khamti

• Tonal system: Most ASR models are designed for non-tonal languages. Speechyou’s model has been trained specifically on Khamti tonal data, distinguishing between high, mid, and low tones with high accuracy.
• Limited training data: With only 10,000 speakers, there are few public datasets. We have built a custom corpus from field recordings, community contributions, and religious texts.
• Devanagari script variation: Different writers may use different Devanagari characters for the same Khamti vowel. Our system normalizes these variations to the most common orthography.
• Code-switching: In everyday speech, Khamti speakers frequently mix in Assamese, Hindi, or Burmese words. Our multilingual model can handle up to three languages in a single audio file.

Use Cases: From Oral History to Podcasts

• Oral history preservation: Record elders telling stories and transcribe them into Devanagari text for community archives.
• Religious text transcription: Buddhist monks often recite scriptures in Khamti. Transcriptions help preserve these texts for study and meditation.
• Subtitling videos: Add SRT subtitles to YouTube videos of local festivals, tutorials, or cultural performances.
• Linguistic research: Field linguists can transcribe interviews with Khamti speakers in real time, freeing up time for analysis.
• Language learning: Learners can listen to audio and follow along with the text, improving pronunciation and reading skills.
• Accessibility: Generate live captions for community meetings or public announcements, helping Deaf or hard-of-hearing community members.
