Comaltepec Chinantec Speech to Text: Preserving a Tonal Language with AI
Comaltepec Chinantec (jùjmi) is a tonal language from the Oto-Manguean family, spoken by around 2,000 people in the town of Comaltepec, Oaxaca, Mexico. Like many indigenous languages, it is at risk of language shift, but technology offers a way to document and revitalize it. Accurate speech-to-text tools can help create written records, subtitles, and educational materials. Speechyou is the first commercial platform to support Comaltepec Chinantec transcription with full tone recognition.
Why Accurate Speech-to-Text Matters for Chinantec
Transcribing Chinantec audio is not just a technical challenge; it is a cultural necessity. Oral traditions, songs, and everyday conversations carry the knowledge of the community. Without a written record, much of this could be lost. Speechyou’s speech-to-text allows users to convert spoken Chinantec into text, preserving it for future generations. The tool supports multiple dialects, including the main Comaltepec variant and the related Tlacoatzintepec and Sochiapan varieties.
The Challenges of Transcribing a Tonal Language
- Tonal complexity: Comaltepec Chinantec uses up to seven tones. A single syllable can have different meanings depending on pitch. Most ASR systems do not handle tone, resulting in errors. Speechyou’s model is trained to detect and output tone marks.
- Limited data: There are few existing transcriptions of Chinantec. Speechyou uses transfer learning from related languages and allows users to correct errors, gradually improving the model.
- Dialectal variation: Tone patterns and vocabulary differ between communities. Speechyou offers dialect-specific models for better accuracy.
Use Cases for Chinantec Transcription
- Oral history preservation: Record interviews with elders and transcribe them to create a permanent archive.
- Subtitle generation: Add SRT or VTT subtitles to videos in Chinantec for YouTube, community broadcasts, or language teaching.
- Education: Create reading materials for bilingual schools. Teachers can transcribe lessons and stories for students.
- Accessibility: Provide real-time captions for deaf community members during events.
- Linguistic research: Analyze grammar, discourse, and phonetics with timestamped transcripts.
