    摘要: A voice wakeup method and a device are provided, relating to the field of terminal technologies. The method includes: receiving, by a third-party device, wakeup messages sent by at least two electronic devices (10, 20, 30), where the wakeup message includes wakeup keyword energy information, the wakeup keyword energy information is used to indicate a wakeup keyword energy value, and the wakeup keyword energy value is a magnitude of audio data received energy in a time period in which a wakeup keyword (1, 2) is located; normalizing wakeup keyword energy values based on ambient sound energy and/or sound collection capabilities of devices, to obtain at least two normalized wakeup keyword energy values; and based on the at least two normalized wakeup keyword energy values, sending a wakeup permission instruction to a first electronic device in the at least two electronic devices (10, 20, 30), and sending a wakeup prohibition instruction to another electronic device other than the first electronic device, where a normalized wakeup keyword energy value of the first electronic device is a maximum value of the at least two normalized wakeup keyword energy values. This helps improve accuracy of waking up a device nearby in a multi-device scenario.

    摘要: The present technology relates to a decoding apparatus, a decoding method and a program which make it possible to obtain sound with higher quality.
    A demultiplexing circuit demultiplexes an input code string into a gain code string and a signal code string. A signal decoding circuit decodes the signal code string to output a time series signal. A gain decoding circuit decodes the gain code string. That is, the gain decoding circuit reads out gain values and gain inclination values at predetermined gain sample positions of the time series signal and interpolation mode information. An interpolation processing unit obtains a gain value at each sample position between two gain sample positions through linear interpolation or non-linear interpolation according to the interpolation mode based on the gain values and the gain inclination values. A gain applying circuit adjusts a gain of the time series signal based on the gain values. The present technology can be applied to a decoding apparatus.
