Siona Speech to Text: Preserving an Amazonian Language with AI

The Siona Language and Its Speakers

Siona is a Western Tucanoan language spoken by the Siona people in the Amazon rainforest, primarily in Colombia and Ecuador. With around 400 native speakers, it is considered endangered. The language is tonal, meaning that pitch changes the meaning of words. For example, the word "bai" can mean "to go" or "to come" depending on the tone. Siona also has nasal vowels, such as /ã/ and /ẽ/, which are represented in the Latin script with a tilde (e.g., "bai̧" for a nasalized form).

Why Accurate Speech to Text for Siona Matters

Transcribing Siona audio is vital for preserving the language and culture. Oral traditions, including creation myths, songs, and daily conversations, are at risk of being lost as older speakers pass away. Automatic speech to text tools can help document these recordings quickly, creating searchable archives for future generations. For linguists, accurate transcription enables detailed analysis of Siona phonology and grammar. For the community, it supports language revitalization by providing written materials for education.

Transcription Challenges Specific to Siona

• Tonal System: Siona uses high and low tones to distinguish words. An ASR model must capture these pitch differences, which most generic systems cannot do.
• Nasal Vowels: The language has phonemic nasal vowels that are often missed by standard transcription tools. Accurate detection is essential for correct spelling.
• Limited Data: With very few transcribed audio datasets available, training a model from scratch is impractical. Speechyou uses transfer learning from related languages to achieve useful accuracy.
• Dialectal Variation: Differences between Siona proper, Secoya, and other varieties can affect vocabulary and pronunciation. Speechyou's model is trained on multiple dialects to improve coverage.

Use Cases for Siona Transcription

• Oral History Preservation: Record and transcribe interviews with elders, creating a digital library of stories and traditional knowledge.
• Language Documentation: Linguists can transcribe field recordings rapidly, accelerating the creation of dictionaries and grammars.
• Subtitles for Community Videos: Generate SRT or VTT subtitles for videos shared on social media, helping younger speakers follow along.
• Educational Materials: Produce transcripts for bilingual school lessons, supporting Siona language classes in local schools.
• Research Transcription: Convert recorded speech into text for academic studies on tonal languages and Amazonian linguistics.
• Accessibility: Provide text alternatives for audio content, benefiting community members with hearing impairments.
