Tanosa Speech to Text: Preserving an Indigenous Language Through AI
Tanosa (Tupian, Brazil) is a language spoken by a few hundred people in the Amazon rainforest. The language is part of the rich linguistic heritage of Brazil, yet it receives very little attention from technology developers. Without digital tools, Tanosa risks being replaced by Portuguese. Speechyou changes that by offering a dedicated speech-to-text and subtitle generator for Tanosa.
The State of Tanosa Transcription
Until now, transcribing Tanosa audio was either done manually by linguists or not done at all. Major transcription services like Google Speech-to-Text, Amazon Transcribe, and Otter.ai do not support Tanosa. OpenAI's Whisper may produce garbled output because it was never trained on Tanosa data. Speechyou fills this gap with a custom model that understands the sounds and grammar of Tanosa.
Why Tanosa Speech-to-Text is Important
- Language Preservation: Every transcribed story becomes a permanent record that can be studied and taught.
- Cultural Vitality: Subtitled videos in Tanosa allow young members to see their language written and spoken.
- Accessibility: Deaf or hard-of-hearing Tanosa speakers can read subtitles in their own language.
- Research: Linguists can quickly obtain accurate transcripts for analysis.
Challenges in Tanosa ASR
Tanosa presents specific challenges:
- Tonal distinctions: Although not heavily tonal, Tanosa uses pitch to differentiate words. Our model pays special attention to these contours.
- Nasalization: Vowels can be nasalized, which is marked in the Latin script with a tilde
~. The ASR must detect nasalization from the audio.
- Code-switching: Many speakers mix Portuguese words. Speechyou's bilingual recognition handles such cases.
Use Cases in Practice
Oral History Projects
Community elders can narrate myths and personal histories in Tanosa. With Speechyou, these recordings are transcribed verbatim in Tanosa orthography. Subtitles in the same language or Portuguese can be added for wider audiences.
Education
Teachers can take spoken Tanosa lessons and convert them into written handouts. Students can practice reading by following along with subtitles during audio playback.
Media Production
Local content creators can produce YouTube videos in Tanosa with accurate subtitles. This increases the visibility of the language online.
