South Bolivian Quechua Speech to Text: Preserving a Living Language With AI

South Bolivian Quechua, known natively as Qhichwa, is spoken by approximately 1.5 million people across the Bolivian departments of Cochabamba, Potosí, Chuquisaca, and Oruro, as well as in the northern provinces of Argentina. Despite its cultural importance — it is an official language of Bolivia — Quechua transcription tools have lagged behind those for Spanish or English. Many commercial platforms ignore Quechua entirely, leaving speakers without automated ways to convert audio into text. Speechyou changes this with a purpose‑built speech‑to‑text engine for South Bolivian Quechua.

Why Accurate Quechua Transcription Matters

The Quechua language is rich in oral tradition: myths, agricultural knowledge, and community laws have been passed down by word of mouth for centuries. As younger generations migrate to cities, these recordings risk being lost. Transcribing them into searchable text creates a permanent record and makes the knowledge accessible to scholars and community members alike. Additionally, Quechua media — radio programs, podcasts, YouTube channels — can benefit from subtitles to reach a global audience. With Speechyou, users can generate SRT and VTT subtitles in 100+ languages, making Quechua content discoverable worldwide.

Specific Challenges and How Speechyou Overcomes Them

• Phonemic contrasts: Quechua has ejective and aspirated consonants (e.g., /pʼ/, /kʰ/). Generic ASR often misses them. Speechyou’s model has been trained on Bolivian Quechua data that includes minimal pairs.
• Dialectal differences: The model recognises four major dialects — Cochabamba, Potosí, Chuquisaca, Oruro — and adapts its output accordingly. Users can select the most relevant dialect if known.
• Code‑switching with Spanish: Many Quechua speakers alternate between languages. Speechyou handles moderate Spanish insertions without breaking the transcription.
• Vowel length: In some dialects vowel length changes meaning. The AI tracks duration cues from the audio waveform.

Use Cases for South Bolivian Quechua Transcription

• Indigenous education: Teachers can transcribe Quechua‑language lessons and assessments, making bilingual education more efficient.
• Oral history projects: NGOs and university projects can quickly convert interviews with elders into text for archives.
• Media subtitles: Documentary filmmakers add Quechua subtitles to reach both indigenous viewers and international audiences.
• Accessibility: Public events or online meetings can get real‑time captions in Quechua.
• Research: Linguists analyse transcribed speech corpora for phonetic, syntactic, and discourse studies.
• Community news: Local Quechua radio programmes are transcribed for print and social media.
