Abstract: To adjust a transmit power for device-to-device communication, a user equipment which performs the device-to-device communication using the transmit power detects that the user equipment enters a coverage area of a radio communication unit. The transmit power of the user equipment for the device-to-device communication is decreased in response to detecting that the user equipment enters the coverage area of the radio communication unit.

Abstract: Improvements in speaker identification and verification are provided via an attention model for speaker recognition and the end-to-end training thereof. A speaker discriminative convolutional neural network (CNN) is used to directly extract frame-level speaker features that are weighted and combined to form an utterance-level speaker recognition vector via the attention model. The CNN and attention model are join-optimized via an end-to-end training algorithm that imitates the speaker recognition process and uses the most-similar utterances from imposters for each speaker.
