How Shaip Helped Build India’s Largest Open-Source Speech Dataset for Project Vaani

Strict Quality Assurance

Audio data had to meet a high bar: no background noise, echoes, phone vibrations, or distortions. Audio was recorded in quiet, echo-free environments. Files underwent rigorous review to meet guidelines for speech clarity, noise levels, metadata accuracy, and speaker verification. Metadata tagging had to be accurate across all files, and all recordings were checked for speaker and location alignment.
