  • Patent number: 10991362
    Abstract: Provided is a target speech signal extraction method for robust speech recognition including: receiving information on a direction of arrival of the target speech source with respect to the microphones; generating a nullformer by using the information on the direction of arrival of the target speech source to remove the target speech signal from the input signals and to estimate noise; setting a real output of the target speech source using an adaptive vector as a first channel and setting a dummy output by the nullformer as a remaining channel; setting a cost function for minimizing dependency between the real output of the target speech source and the dummy output using the nullformer by performing independent component analysis (ICA) or independent vector analysis (IVA); setting an auxiliary function to the cost function; and estimating the target speech signal by using the cost function and the auxiliary function.

  • Patent number: 10930277
    Abstract: A voice interaction architecture has a hands-free, electronic voice controlled assistant that permits users to verbally request information from cloud services. Since the assistant relies primarily, if not exclusively, on voice interactions, configuring the assistant for the first time may pose a challenge, particularly to a novice user who is unfamiliar with network settings (such as wife access keys). The architecture supports several approaches to configuring the voice controlled assistant that may be accomplished without much or any user input, thereby promoting a positive out-of-box experience for the user. More particularly, these approaches involve use of audible or optical signals to configure the voice controlled assistant.

  • Patent number: 10923101
    Abstract: A system, a computer program product, and method for controlling synthesized speech output on a voice-controlled device. The voice-controlled device recognized that speech input is being received. The voice-controlled device outputs synthesized speech based on the speech input. While outputting synthesized speech based on the audio is captured. The voice-controlled device recognized the audio input as speech and pausing the outputting of synthesized speech. Otherwise, in response to the captured audio not being recognized as speech and above a settable background noise threshold, pausing the outputting of synthesized speech. The paused output of speech based on the synthesized speech input is resumed after the pausing of the output of synthesized speech being within a settable pause timeframe.

  • Patent number: 10607101
    Abstract: Images in bitonal formats often include watermarks, stamps, or other patterns and artifacts. These patterned artifacts may be represented as a series of geometric points, dots, and/or dashes in the general shape of the original pattern. These patterned artifacts make other processes such as optical character recognition (OCR) difficult or impossible when items or pixels of interest are also found within the pattern of such artifact(s). Current patterned artifact removal solutions use methods of erosion to minimize the unwanted patterned artifact. However, such methods also erode the pixels/items of interest which, in turn, cause failures in other processes, such as OCR, that are desired to be carried out on or with the image.

  • Patent number: 10567736
    Abstract: A three-dimensional object detection apparatus includes an input interface and a controller. The input interface accepts input of first and second images having mutual parallax in a first direction. The controller generates a parallax image that uses a pixel value to represent a difference in the first direction between positions of a subject in the first image and in the second image and divides the parallax image into a plurality of partial regions extending along a second direction. For each partial region, the controller segments a distance in the direction towards the subject into a plurality of distance intervals; and calculates, on the basis of a pixel count of pixels belonging to the distance interval, an evaluation value of a three-dimensional object belonging to the distance interval. The controller uses a different threshold for each distance interval to determine whether or not a three-dimensional object is present.
