Koya (Telugu script) Speech to Text: A Complete Guide
Koya Speech to Text: Preserving a Dravidian Language Through AI
The Koya language (Koya: కోయ) is a Dravidian language spoken by the Koya people in the eastern Indian states of Andhra Pradesh, Telangana, Odisha, and Chhattisgarh. With an estimated 300,000 speakers, it is considered a minority language with a rich oral culture. Despite its vitality within communities, Koya lacks extensive digital resources, making accurate speech-to-text tools essential for preservation and modern communication.
Why Accurate Koya Speech Recognition Matters
Transcribing Koya audio is crucial for several reasons:
- Preservation of oral traditions: Folk tales, songs, and ceremonial speeches can be archived in text.
- Education: Creating subtitles for Koya-language instructional videos helps with literacy in the Telugu script.
- Accessibility: Deaf or hard-of-hearing Koya speakers can access spoken content through captions.
- Research: Linguists and anthropologists benefit from systematic transcriptions.
Without a reliable ASR, these tasks require manual transcription, which is time-consuming and expensive.
Challenges Unique to Koya
Koya presents several challenges for automatic transcription:
1. Retroflex and Dental Contrast
Koya distinguishes retroflex stops (e.g., /ʈ/, /ɖ/) from dental stops (e.g., /t̪/, /d̪/). For example, kōṭa "fort" vs. kōta "monkey". Generic ASR models often merge these, leading to errors.
2. Vowel Length
Short and long vowels change word meaning. pal "tooth" and pāl "milk" are distinguished only by vowel length. Speechyou is trained to capture duration accurately.
3. Dialectal Variation
Koya dialects such as Dorla and Odisha Koya have distinct phonologies. A model trained only on standard Koya may perform poorly on Dorla speech.
4. Limited Training Data
Being a low-resource language, large annotated datasets are unavailable. Speechyou uses transfer learning from related Dravidian languages to bootstrap performance.
Use Cases for Koya Speech-to-Text
- Oral history preservation: Elders' stories can be transcribed for future generations.
- Subtitling videos: Educational content becomes accessible with Telugu-script SRT files.
- Transcribing folk songs: Cultural heritage is documented in written form.
- Community radio: Broadcaster speech can be turned into text for newsletters.
- Healthcare: Patient instructions in Koya can be recorded and transcribed for records.
