摘要： This disclosure describes systems, methods, and devices related to noise suppression processing. A device may establish a connection to a connected device. The device may calculate a first SNR of a first sample of a first audio stream from the connected device. The device may calculate a second SNR of a second sample of a second audio stream from a first device. The device may compare a difference of the first SNR and the second SNR to a Delta SNR threshold. The device may detect ambient noise level conditions and the Delta SNR threshold is based on the ambient noise level conditions. The device may determine whether to apply system-level preprocessing based on the comparison.

摘要： Methods for automatic calibration of a braille interface. In embodiments, a user begins typing braille characters in 2×3 matrix into an interface without an initial calibration step. The implementing system detects the patterns of the keystrokes and determines the orientation and placement of the user's hands by comparing the keystrokes against known braille characters, identifying which row and column of the 2×3 matrix within which each finger is positioned. The interface is then calibrated based on the identified positions of the fingers within the 2×3 matrix. For touch interfaces, the surface area of each finger may also be used to enhance identification of fingers. Other embodiments may be described and/or claimed.
