Chol Speech to Text: Preserving a Mayan Language Through AI

Chol (Ch'ol) is a Mayan language spoken primarily in the Mexican state of Chiapas, with a population of around 200,000 speakers. It belongs to the Cholan-Tzeltalan branch of the Mayan language family and is closely related to Chontal and Tzeltal. Despite its vitality, Chol faces pressure from Spanish and urbanization. Accurate speech-to-text technology can help document and revitalize the language by making spoken content accessible in written form.

Why Accurate Chol Transcription Matters

For Chol speakers, having a reliable speech-to-text tool means they can transcribe interviews, record oral histories, and generate subtitles for videos without relying on Spanish. This is especially important for:

• Language documentation: Linguists and community members can create searchable archives of Chol speech.
• Education: Schools and universities can produce Chol-language learning materials with subtitles.
• Media: Indigenous radio and TV stations can subtitle their content for a wider audience.
• Healthcare: Health messages in Chol can be transcribed and translated into Spanish for better outreach.

The Challenge of Chol Phonology

Chol has a complex phonological system that poses challenges for automatic speech recognition. Key features include:

• Ejective consonants: [pʼ], [tʼ], [kʼ], [chʼ] – these are produced with a glottalic egressive airstream and are rare in other languages.
• Glottalized vowels: creaky voice vowels that change meaning.
• Pitch accent: tonal distinctions on syllables that differentiate words.
• Vowel length: short vs. long vowels are phonemic.

Most commercial ASR systems are not trained on these features, leading to poor accuracy. Speechyou's model is specifically trained on Chol audio data, including recordings from the Tila and Tumbalá dialects, to ensure these sounds are recognized correctly.

Dialectal Variation in Chol

Chol has several dialects, primarily Tila, Tumbalá, and Sabanilla. While they are mutually intelligible, there are differences in vocabulary, pronunciation, and some grammatical structures. Speechyou's model is trained on multiple dialects to provide consistent transcription quality across regions.
