Data Collection for Face and Speech Recognition

Through data collection, our client improved the biometric system for facial and voice recognition by 21%

Industry and use case:



10,000 attack videos

Project duration:

21 days

Our Challenge:

The client approached us to gather data to enhance their facial and speech recognition system. The client’s technical specifications involved unique offline data collection (photos, videos, and audio), strict criteria for sound and filming format, and the necessity to gather data from 1000 participants

Our Solution:

To collect this dataset, we organized 5 studios and invited people to participate in data collection for compensation using promoters. Each studio had a manager assisting participants with recording and overseeing the data collection process. Each studio hosted 8-10 individuals per day


  • The client improved their biometric system for facial and voice recognition by 21%
  • We gathered a unique dataset with over 400,000 data units from 1000 offline participants
  • We assembled a team of promoters and compiled a list of suitable locations for offline projects across the city (NDA)
