Purepecha Speech to Text: Preserving a Language Through AI

Purepecha (P'urhépecha) is an indigenous language of Mexico, spoken by around 200,000 people in the state of Michoacán. Unlike most other languages in the region, Purepecha is a language isolate, meaning it has no known relatives. Its unique sound system includes ejective consonants (p', t', k'), phonemic vowel length, and a rich morphology. Despite its cultural significance, Purepecha is endangered as younger generations shift to Spanish. Accurate speech-to-text technology offers a powerful way to document, transcribe, and revitalize the language.

Why Purepecha Transcription Matters

Transcribing Purepecha audio is essential for:

• Language documentation: Linguists and community members can create written records of oral traditions.
• Education: Teachers can produce lesson transcripts and bilingual reading materials.
• Media: Content creators can add Purepecha subtitles to videos, making them accessible to speakers and learners.
• Accessibility: Deaf community members can follow Purepecha events through captions.

Generic transcription tools like Otter.ai, Happy Scribe, or Google Speech-to-Text do not support Purepecha at all. This leaves speakers with no automated option. Speechyou fills this gap with a dedicated Purepecha ASR model.

Challenges in Purepecha Speech Recognition

Purepecha poses several challenges for automatic speech recognition:

• Ejective consonants: Sounds like /p'/, /t'/, /k'/ are rare in world languages and often misrecognized by standard models.
• Vowel length: Short vs. long vowels can change word meaning (e.g., k'eri 'big' vs. k'eeri 'to be lying down').
• Dialectal variation: Sierra, Lake, and Cañada dialects differ in pronunciation and vocabulary.
• Limited data: Few transcribed recordings exist, making it hard to train deep learning models.

Speechyou overcomes these using transfer learning, data augmentation, and a custom acoustic model fine-tuned on Purepecha speech.

Use Cases for Purepecha Transcription

• Oral history preservation: Transcribe interviews with elders to create digital archives.
• Community media: Generate subtitles for local news and YouTube channels.
• Language learning: Convert audio lessons into text for study materials.
• Research: Linguists can quickly transcribe field recordings for analysis.
• Accessibility: Provide real-time captions for community meetings.
