FAQ
Q: What does the Bundeli Speech Dataset contain?
A: The Bundeli Speech Dataset contains 160 hours of high-quality audio recordings from native Bundeli speakers across Madhya Pradesh and Uttar Pradesh. The dataset includes 823 files in MP3/WAV format totaling approximately 409 MB, with transcriptions, speaker demographics, regional information from Bundelkhand region, and linguistic annotations optimized for machine learning applications.
Q: Why is Bundeli speech technology important?
A: Bundeli is spoken by millions in the historically significant Bundelkhand region but remains underrepresented in language technology. This dataset enables voice interfaces that serve large populations in central India, supports digital inclusion for Bundeli speakers, and helps preserve linguistic heritage of a region known for its distinctive culture and historical importance in Indian history.
Q: How does the dataset capture Bundelkhand’s cultural context?
A: Bundelkhand has rich cultural traditions including folk music, oral history, and traditional knowledge systems. The dataset captures authentic Bundeli speech reflecting this cultural context, supporting development of applications that preserve cultural heritage, document oral traditions, and make regional knowledge accessible through voice technology while respecting cultural distinctiveness.
Q: What linguistic features distinguish Bundeli?
A: Bundeli is an Indo-Aryan language with distinctive phonological and grammatical features different from standard Hindi. The dataset includes linguistic annotations marking Bundeli-specific characteristics including unique vocabulary, pronunciation patterns, and grammatical structures. This ensures trained models recognize Bundeli as distinct regional language rather than Hindi dialect.
Q: Can this dataset support rural development?
A: Yes, Bundelkhand is predominantly rural with significant agricultural population. Voice interfaces built with this dataset can deliver development information, agricultural guidance, government services, and educational content in Bundeli, overcoming literacy barriers and improving access to technology-enabled development programs in underserved central Indian regions.
Q: What is the demographic distribution?
A: The dataset includes 46% female and 54% male speakers with age distribution of 34% aged 18-30, 25% aged 31-40, 18% aged 40-50, and 23% aged 50+. Cross-regional representation from Madhya Pradesh and Uttar Pradesh ensures comprehensive coverage.
Q: What applications are suitable for Bundeli speech technology?
A: Applications include cultural heritage documentation and digital archives, agricultural advisory systems for Bundelkhand farmers, voice interfaces for rural development programs, regional entertainment content transcription, educational tools for local schools, and information systems serving communities in Madhya Pradesh and Uttar Pradesh portions of Bundelkhand.
Q: How does this support linguistic preservation?
A: Bundeli faces pressure from dominant languages like Hindi. This dataset supports language preservation by enabling modern technology applications in Bundeli, making the language relevant for younger generations, documenting linguistic features for posterity, and ensuring Bundeli remains viable in digital age through voice-enabled services and applications.
How to Use the Speech Dataset
