Preserving Sochiapam Chinantec with AI-Powered Speech-to-Text

Sochiapam Chinantec (Júmi) is an Oto-Manguean language spoken in the town of Sochiapan, Oaxaca, Mexico. With fewer than 3,000 speakers, it is classified as severely endangered. The language is rich in tonal contrasts, with five distinct tones that change the meaning of words. For decades, documentation efforts relied on painstaking manual transcription by linguists, which is time-consuming and expensive. Now, Speechyou offers a dedicated speech-to-text solution for Júmi, enabling fast, accurate transcription and subtitle generation for community members, researchers, and educators.

Why Accurate Speech-to-Text for Júmi Matters

Accurate ASR for Júmi is not just a technical achievement; it is a tool for language revitalization. Elder speakers hold a wealth of traditional knowledge, from healing practices to oral narratives. By transcribing their speech, communities can create searchable archives that younger generations can access. Subtitles in Júmi also help in bilingual education, where children learn both Spanish and their ancestral language. Moreover, linguists can use transcripts to study tone patterns, syntax, and lexical variation without spending months on manual transcription.

Challenges in Transcribing Sochiapam Chinantec

• Tonal Complexity: Júmi has five tones (high, low, mid, falling, rising). A single syllable can have different meanings based solely on pitch. Speechyou's model is trained to detect these tones and outputs diacritics in the standard INALI orthography.
• Limited Data: With few digital recordings, general ASR models fail. Speechyou uses transfer learning from related Oto-Manguean languages and allows users to upload custom audio to improve accuracy.
• Dialectal Variation: The Sochiapam area has at least three subdialects, with differences in tone realization and consonant inventory. Speechyou's model handles these variations through adaptive acoustic modeling.

Use Cases in the Community

• Oral History Preservation: Record interviews with elders and automatically generate timestamped transcripts. These can be stored in digital archives accessible via the web.
• Subtitling Cultural Videos: Add Júmi subtitles to videos of traditional dances, ceremonies, or cooking demonstrations. Speechyou supports SRT and VTT formats for easy upload to YouTube or Vimeo.
• Classroom Materials: Teachers can transcribe bilingual lessons and create reading materials for students. The transcripts can be exported as plain text or interactive PDFs.
• Healthcare Communication: Health workers can record messages in Júmi about hygiene, nutrition, or disease prevention and get transcripts to share with community health promoters.
• Linguistic Research: Field linguists can upload field recordings and receive a first-pass transcript that includes tonal markers, drastically reducing manual effort.

How Speechyou Helps

Speechyou is built specifically for low-resource and endangered languages. The Júmi model is trained on a curated dataset of spoken Chinantec, augmented with synthetic tonal data. Users can start transcribing immediately without any setup. The platform supports real-time and batch processing, and the output can be edited in a built-in web editor. For privacy-conscious users, speech data is processed on secure servers and deleted after transcription. Speechyou also offers an API for integration with mobile apps or documentation tools.
