Samsung Electronics Co. Ltd. Develops Robot for Acquiring Learning Data and Method for Controlling Thereof

Strategic Insights -

The patent, filed by Junghoe Kim, Saeyoung Kim, Yongkook Kim, Hyeontaek Lim, Boseok Moon, all from Suwon-si, South Korea, for Samsung Electronics Co. Ltd., details a robot capable of actively acquiring learning data for learning a speech recognition model and a method for controlling thereof. The robot and its corresponding control method are designed to improve speech recognition performance by accurately recognizing user speech in various environments. The robot's unique features include its ability to control external devices, such as air conditioners and air purifiers, to generate noise for learning speech recognition.

Key Takeaways:

  • The robot for acquiring learning data consists of a speaker, microphone, driver, communication interface, memory, and at least one processor.
  • The robot's processor is configured to control the communication interface to transmit a command to an external device based on pre-stored environment information while operating in a learning mode.
  • The robot outputs first user speech for learning while an external device, responsive to the command, outputs a noise, and learns a speech recognition model based on the noise and first user speech for learning acquired through the microphone.
  • The control method of the robot includes transmitting a command to an external device around the robot based on pre-stored environment information, outputting first user speech for learning, and learning a speech recognition model based on the noise and first user speech for learning.
  • The robot's processor is further configured to analyze an audio signal to identify a speech period and non-speech period, and determine a second speech recognition section for learning as having a second start time point and a second end time point based on a first start time point and a first end time point of the speech period.
  • The robot operates in the learning mode based on a preset event being detected, which comprise at least one of entering a time zone set by a user, a time zone at which learning data was acquired in the past, or the user being detected as going outside.
  • The robot's processor is configured to control the communication interface to transmit the speech recognition model to an external device capable of recognizing speech.

Statistics:

  • The patent was filed on July 21, 2023, and published online on July 29, 2025.
  • The patent has 20 claims, including claims related to the robot's processor, communication interface, and control method.
  • The robot consists of a speaker, microphone, driver, communication interface, memory, and at least one processor.
  • The control method of the robot includes 10 steps, including transmitting a command to an external device, outputting first user speech for learning, and learning a speech recognition model.
