Northern Huastec Speech to Text: Empowering the Tének Language with AI

A Language at the Crossroads of History

Northern Huastec (ISO 639‑3: nhy), self‑named Tének, is a Mayan language spoken by around 150,000 people primarily in the Mexican states of San Luis Potosí and Veracruz, with smaller communities in Tamaulipas. It belongs to the Huastecan branch of the Mayan family, which separated from the main Mayan trunk over 4,000 years ago. Today, Huastec is an endangered language under pressure from Spanish, but grassroots revitalization efforts are growing, and digital tools like speech to text for Huastec are critical for preserving and promoting the language.

Why Accurate Transcription Matters for Huastec

Transcribing Huastec audio is essential for:

• Documenting oral traditions, songs, and ritual speech.
• Creating bilingual educational materials (Huastec‑Spanish) for schools in the Huasteca.
• Producing subtitles for community videos and YouTube channels.
• Supporting linguistic research on tone and glottalization.
• Providing accessibility for Deaf Huastec speakers who read written Tének.

Most commercial transcription tools ignore minority languages like Huastec. Speechyou fills that gap with a dedicated model trained on native speaker data.

Specific Challenges in Huastec ASR

Glottalized Consonants

Huastec contrasts plain and glottalized stops: /t/ vs /tʼ/, /k/ vs /kʼ/. Mishearing /kʼaʔ/ (rain) for /kaʔ/ (hand) changes meaning entirely. Our model is trained on minimal pairs to maintain this contrast.

Tonal System

Long vowels carry one of three tones: high (áa), low (àa), or falling (âa). For example, kʼáan (yellow) vs kʼàan (lime) differ only in tone. Speechyou uses pitch‑tracking features to correctly assign tone marks.

Dialectal Variation

Northern Huastec includes at least three major dialects (Potosino, Veracruzano, Tantoyuca) with lexical and phonetic differences. Speechyou offers a dialect selection to improve accuracy for each variant.
