Achagua Speech to Text: Preserving an Amazonian Language with AI

Achagua is a member of the Arawakan language family, spoken in the Meta department of Colombia, near the Casanare River. With only a few hundred speakers, it is critically endangered. The language is closely related to Piapoco and other Arawak languages of the region. Unlike Spanish, which dominates daily life, Achagua is used primarily in the home and in traditional ceremonies. Accurate speech-to-text technology can help document and revitalize this precious linguistic heritage.

Why Accurate Speech-to-Text for Achagua Matters

For endangered languages, every recording is a treasure. Oral histories, songs, and everyday conversations carry knowledge that cannot be replaced. Manual transcription is time-consuming, often requiring linguists to spend hours per hour of audio. Speechyou offers an automated solution that transcribes Achagua audio with high accuracy, freeing up time for analysis and preservation.

Moreover, subtitles created from transcripts make Achagua content accessible to a wider audience. Younger generations who may not be fluent can follow along with subtitles, aiding language learning. Researchers can search transcripts for specific words or phrases, accelerating linguistic analysis.

Transcription Challenges Specific to Achagua

Achagua presents several challenges for automatic speech recognition:

• Nasal vowels: The language distinguishes between oral and nasal vowels, such as /a/ vs /ã/. Misrecognition of nasal vowels can change meaning.
• Aspirated stops: The stops /pʰ/, /tʰ/, /kʰ/ are contrastive with plain /p/, /t/, /k/. These are often conflated by generic ASR.
• Low data availability: Most ASR systems require large amounts of transcribed data, which does not exist for Achagua. Speechyou uses transfer learning from related Arawakan languages and augment with field recordings.
• Code-switching: Speakers often mix Spanish and Achagua, especially for modern concepts. The model must handle both languages seamlessly.

Speechyou's Achagua model has been trained to overcome these issues, achieving reliable transcription even in challenging conditions.

Use Cases: From Oral History to Subtitles

• Oral history preservation: Elders record stories and myths. Speechyou transcribes them, creating a searchable archive.
• Language learning: Teachers can create subtitled videos for learners, with the Achagua text displayed alongside Spanish or English translations.
• Community radio: Stations that broadcast in Achagua can generate transcripts for news and programs, improving accessibility.
• Linguistic research: Field linguists can upload recordings and obtain draft transcripts, editing them to finalize publications.
• Accessibility: Hard-of-hearing community members can follow spoken content with subtitles.
