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. 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: 8kHz
