摘要： A user device having an active application periodically detects for a hands-off state of the user device. Upon detecting a hands-off state, the user device affects at least one of the active application and the user device. Prior to affecting at least one of the active application and the user device, the user device detects for one or more of a connection between the user device and another device, and an application of pressure to the user device. If either is detected the, the user device bypasses affecting at least one of the active application and the user device.

摘要： The present invention relates to a method and a background estimator in voice activity detector for updating a background noise estimate for an input signal. The input signal for a current frame is received and it is determined whether the current frame of the input signal comprises non-noise. Further, an additional determination is performed whether the current frame of the non-noise input comprises noise by analyzing characteristics at least related to correlation and energy level of the input signal, and background noise estimate is updated if it is determined that the current frame comprises noise.

摘要： The embodiments of the present invention relates to a primary voice activity detector and a method thereof. By using the method of the embodiments it is possible to determine whether frames of an input signal comprise voice. That is achieved by receiving a frame of the input signal, determining a first SNR of the received frame, comparing the determined first SNR with an adaptive threshold, and detecting whether the received frame comprises voice based on said comparison. The adaptive threshold is at least based on total noise energy of a noise level, an estimate of a second SNR and on energy variation between different frames.

摘要： When a delivered speed of a listening speech (speech speed) is slowed down, a connection order generator (8) always monitors a data length of input speech, an output data length calculated previously by a conversion function concerning a preset scaling factor, and a data length of actual output speech in predetermined processing unit, then decides connection order so as not to cause inconsistency among them. The speech data and the connection data are connected without omission of speech information by controlling a speech data connector (9). When power of an input signal data is calculated to discriminate a speech interval and a non-speech interval, a threshold value for power is decided according to a maximum value of the power and difference between the maximum value and a minimum value.
