Mixtec Speech to Text: Accurate Transcription and Subtitles for Tu'un Savi

Mixtec (Tu'un Savi) is a vibrant Oto-Manguean language spoken primarily in the Mexican states of Oaxaca, Puebla, and Guerrero. With an estimated 500,000 speakers, it is one of the most widely spoken indigenous languages in the Americas. Yet due to its tonal nature and high dialectal fragmentation, accurate automatic transcription has remained elusive until now.

Why Speech-to-Text Matters for Mixtec

For many Mixtec communities, language is the key to identity and cultural survival. However, preserving oral traditions, recording community meetings, or creating accessible media requires reliable transcription. A mixtec speech to text tool that respects the language's phonology can:

• Convert oral histories into searchable text for archives and schools.
• Generate subtitles for videos in Mixtec, reaching both hearing-impaired and Spanish-speaking audiences.
• Assist linguists and anthropologists in documenting endangered varieties.
• Enable Mixtec speakers to access digital services in their own language.

Transcription Challenges Unique to Mixtec

Developing an automatic transcription system for Mixtec involves several hurdles:

Tonal System

Mixtec uses three phonemic tones: high (´), low (`), and mid (unmarked). For example, 'ndà'à' (hand) vs 'ndá'á' (thick) differ only in tone. Speechyou’s model incorporates a tonal classifier layer that predicts tone marks from acoustic cues, achieving over 90% tonal accuracy in clean recordings.

Dialect Variation

There are at least 12 distinct Mixtec dialects, some with lexical differences of 40% or more. Our model is trained on a multi-dialect corpus including San Juan Colorado, San Miguel El Grande, and Santa María Zacatepec. Users can select a dialect profile for improved results, and we support custom vocabulary for local place names and cultural terms.

Limited Digital Resources

Unlike widely spoken languages, Mixtec has few publicly available speech databases. To overcome this, Speechyou leverages transfer learning from related tonal languages and active community data collection. Users can contribute recordings to help the model learn new voices and dialects.

Use Cases in Practice

Oral History Preservation

Elders in Mixtec villages are often the last speakers of vanishing local dialects. Recording their stories and obtaining accurate transcriptions allows libraries to build archives of traditional knowledge, songs, and rituals. The exportable SRT and VTT subtitles ensure these recordings can be shared on platforms like YouTube with proper captions.

Bilingual Education

In Oaxaca's bilingual schools, teachers use Mixtec to explain concepts before switching to Spanish. Speechyou can transcribe daily lessons for later review by absent students or parents who want to follow along. The tool’s timestamped output helps align text with spoken segments.

Community Radio and Podcasts

Local radio stations broadcasting in Mixtec can generate subtitles for their programs, making them accessible to deaf community members and non-speakers learning the language. Podcasters can publish show notes and quotes from interviews instantly.

Legal and Healthcare Interpreting

Mixtec-speakers in legal and medical settings often rely on interpreters, but records are scarce. With a simple audio recording of consultations, Speechyou produces a written log that can be translated or kept for compliance. All processing is encrypted and compliant with data protection laws.
