Tepetotutla Chinantec Speech to Text: Preserving a Tonal Language with AI
The Language and Its Speakers
Tepetotutla Chinantec (endonym: Jmiih) is a language of the Chinantecan family, spoken by around 1,000 people in the town of Tepetotutla and surrounding villages in Oaxaca, Mexico. It is a tonal language, meaning that pitch plays a crucial role in distinguishing word meanings. For example, the word for "water" and "deer" differ only in tone. The language is endangered, with most speakers over 40, making preservation efforts urgent.
Why Accurate Speech-to-Text Matters
Transcription is a cornerstone of language documentation. It allows oral stories, songs, and conversations to be stored, searched, and studied. For Tepetotutla Chinantec, accurate speech-to-text opens the door to:
- Creating reading materials for bilingual education
- Preserving elders' knowledge for future generations
- Enabling subtitle generation for community media
- Supporting linguistic research on tone and syntax
Without a reliable transcription tool, these tasks are left to manual work, which is slow and inconsistent. Speechyou provides an AI-powered solution that respects the tonal complexity of the language.
Specific Transcription Challenges
Tones
Tepetotutla Chinantec has seven tones: high, mid, low, rising, falling, peaking, and dipping. Most ASR systems ignore tone, causing errors. Speechyou uses a tonal-aware model trained on Chinantec data from the region.
Dialectal Variation
Even within Tepetotutla, there are subtle differences between villages. Speechyou adapts via a custom vocabulary—users can upload sample texts to personalize the model.
Lack of Resources
There are few online texts in Tepetotutla Chinantec. Speechyou overcomes this by using transfer learning from related languages and allowing community contributions to improve accuracy over time.
Use Cases in Practice
- Oral history preservation: Transcribe interviews with elders about traditional medicine, legends, and daily life.
- Education: Teachers can convert spoken lessons into printable worksheets for students learning to read Jmiih.
- Podcasts: A community podcast can be transcribed and subtitled, reaching both hearing and non-hearing audiences.
- Research: Linguists can upload field recordings and get timestamped transcriptions in minutes, not days.
- Accessibility: Deaf members of the community can read transcriptions of public announcements.
