South Bolivian Quechua Speech to Text: Preserving Voices, Unlocking Content

Quechua is a family of languages spoken by an estimated 8 to 10 million people across the Andes, from Colombia to Argentina. Among its many varieties, South Bolivian Quechua (ISO 639-3: quy) is one of the most vibrant, with over two million speakers concentrated in the central and southern highlands of Bolivia. Communities in Cochabamba, Chuquisaca, Potosí, and parts of Oruro use Quechua daily in homes, markets, radio, and even local government. Yet the language remains severely underrepresented in digital services.

Why Speech to Text for Quechua Matters

Reliable Quechua speech to text opens doors for speakers and researchers alike. Oral tradition is central to Quechua culture — elders pass down stories, agricultural knowledge, and spiritual concepts through spoken word. Transcribing these recordings preserves them for future generations. In education, bilingual schools struggle to find Quechua‑language materials; automatic transcription can generate reading texts from spoken lessons. For media creators, Quechua subtitle generation makes indigenous content accessible to both Quechua‑ and Spanish‑speaking audiences, boosting reach and inclusivity.

Specific Transcription Challenges

• Vowel allophony: The three basic vowels /a/, /i/, /u/ change quality depending on adjacent consonants (especially uvulars). For example, /u/ becomes [o] before /q/. Standard ASR models mistakenly flatten these distinctions.
• Dialectal differences: A speaker from Cochabamba may pronounce qhari (man) with a clear [q], while a speaker from Potosí might use [χ] or even a glottal stop. No single model can cover all variants without dedicated training.
• Spanish influence: Code‑switching is common. Words like gobierno (government) or iglesia (church) are uttered with Quechua phonetics. Our Quechua transcription model is trained on bilingual data to handle mixed utterances accurately.
• Orthographic variation: Although the Latin script is standard, writers differ on representing certain sounds (e.g., vs. ). Speechyou exports normalized text according to the official Bolivian Quechua alphabet.

Key Use Cases

• Oral history preservation: Community archives can transcribe hundreds of hours of elder interviews without manual effort.
• Education: Teachers create subtitled videos for bilingual students, reinforcing reading skills.
• Media: Podcasts and YouTube channels like Qhichwa Radio add subtitles to reach a wider audience.
• Research: Linguists analyze syntactic patterns from automatically generated transcripts.
• Accessibility: Quechua deaf community gains access to captioned news and entertainment.
• Local governance: Municipal councils transcribe Quechua‑language proceedings for official records.
