San Jerónimo Tecóatl Mazatec Speech to Text: Preserving a Tonal Language with AI

San Jerónimo Tecóatl Mazatec, known natively as En ngomá, is a language spoken by around 1,000 people in the municipality of San Jerónimo Tecóatl, Oaxaca, Mexico. It is part of the Mazatecan branch of the Otomanguean language family, which is known for its complex tonal systems. Like many indigenous languages in Mexico, it faces pressures from Spanish dominance and generational shift. Accurate speech-to-text technology can play a vital role in documenting, teaching, and revitalizing this language.

Why Mazatec Speech Recognition Matters

Transcribing San Jerónimo Tecóatl Mazatec audio to text is essential for several reasons:

• Language preservation: Oral histories, songs, and everyday conversations can be archived as written records.
• Education: Teachers can create transcriptions for language classes and literacy materials.
• Media accessibility: Subtitling videos in Mazatec helps speakers and learners engage with content.
• Research: Linguists need accurate transcriptions for phonetic and grammatical analysis.

Without AI tools, transcription of Mazatec speech is slow and expensive, often requiring trained native speakers. Speechyou automates this process while maintaining high accuracy.

Challenges in Transcribing San Jerónimo Tecóatl Mazatec

Tonal Complexity

Mazatec languages use pitch to distinguish word meanings. In San Jerónimo Tecóatl Mazatec, there are at least four tones: high, low, rising, and falling. For example, the word for 'pineapple' and 'toad' differ only in tone. Speechyou's model incorporates tonal analysis to capture these contrasts.

Limited Training Data

Orthographic Variation

There is no single standardized writing system for Mazatec. Some speakers use the alphabet developed by the Summer Institute of Linguistics, while others use adaptations. Speechyou allows users to select from common orthographic conventions, including tone marking with numbers or diacritics.
