Success Stories


The customer wants to enrich the voice commands in their newly launched smart speaker to allow users to control their smart home devices with voice. Datatang needs to collect data from 10,000 people, covering eight dialects and meeting the age requirement from 3 to 50 years old. The task is efficiently completed through using the our annotation platform, which has online audio automatic quality inspection function and support data upload functions through API.

Voice Command Recognition for Smart Home

The client wants to improve the scene recognition and detection technology of the sweeping robot, and needs to capture more than 200 home scenarios. With years of experience in project management and implementation, Datatang completed the collection of 600,000 images and integrated 160 labels into 4 groups of large labels(each of large labels contains 5-38 small category labels), after that we annotated the images. The labeling efficiency was greatly improved in that way.
