US11228680B2 Calling party validation
In order to confirm that a telephone call received by a network termination on a first connection is from a trusted party, the called party connects over a second, independent, connection 7 to a server associated with the trusted party and shares a code with the server. That code is then transmitted over the first connection and, if the connection is genuine, it is intercepted by the server which generates a message over the second connection confirming that the code has been matched. This gives the called party assurance that the call is from a party associated with the trusted server. If a rogue caller attempts to call the termination, the called party's transmission of the shared code will be routed over the caller's connection, which is not associated with the trusted server, so no match will be identified by the server and no confirmation is returned over the second connection.

US11227578B2 Speech synthesizer using artificial intelligence, method of operating speech synthesizer and computer-readable recording medium
A speech synthesizer using artificial intelligence includes a memory configured to store a first ratio of a word classified into a minor class among a plurality of classes and a synthesized speech model, and a processor configured to determine a class classification probability set of the word using the word, the first ratio and the synthesized speech model. The first ratio indicates a ratio in which the word is classified into the minor class within a plurality of characters, the plurality of classes includes a first class corresponding to first reading break, a second class corresponding to second reading break greater than the first break and a third class corresponding to third reading break greater than the second break, and the minor class has a smallest count among the first to third classes.
US11227577B2 Noise cancellation using dynamic latency value
One embodiment provides a method, including: detecting audio being supplied across an electronic communication medium, wherein the audio comprises at least one noise other than a speaker; minimizing the at least one noise by dynamically adjusting a latency of the audio being supplied to a recipient, wherein the minimizing comprises adjusting the latency to a value allowing for a noise cancelling algorithm to minimize the at least one noise; and providing the audio having the minimized at least one noise to the recipient. Other aspects are described and claimed.
US11227576B2 Continuous degree of freedom acoustic cores
An acoustic liner and a method of attenuating noise are provided. The acoustic liner includes a face sheet, a back sheet spaced from the face sheet, and a core layer extending between the face sheet and the back sheet. The core layer includes a plurality of resonant cells, each resonant cell including at least one cell wall coupled to the back sheet along a cell wall base edge. The at least one cell wall extends from the back sheet at an angle toward the face sheet. The at least one cell wall further coupled to the face sheet along a cell wall top edge. The resonant cell is formed in a predetermined shape and contains a volume in a space defined by the at least one cell wall, the back sheet, and the face sheet. The cell wall base edge length is greater than the cell wall top edge length.
