## About the Dataset
### 788 hours

This audio dataset contains 788 hours of Hindi Speech Data in various domains, recorded by speakers from India.

Domain distribution per dataset:

- 198.77 hours of Banking
- 206.08 hours of Insurance
- 191.95 hours of Retail

Defined.ai creates scenarios for our crowd members to follow, which they study beforehand. They then record a conversation, one speaker playing the agent, the other speaker “playing out” the scenario with spontaneous content. The recording is done via telephony and is saved in 8kHz 16 bit per channel. That content is then transcribed.

The dataset is covered by [Defined.ai's standard license agreement](https://www.defined.ai/dataset/data-license-agreement). The license agreement is perpetual and allows for the commercialization of all models built on the data.

Other characteristics:

- Audio format: WAV
- Recording environment: noisy, silent
- Bits per sample: 16
- Communication band: broadband
- Sample rate: 8Hz
