Abstract: A method for detecting an audio signal and an apparatus, where the method includes determining an input audio signal as a to-be-determined audio signal, determining an enhanced segmental signal-to-noise ratio (SSNR) of the audio signal, where the enhanced SSNR is greater than a reference SSNR, and comparing the enhanced SSNR with a voice activity detection (VAD) decision threshold to determine whether the audio signal is an active signal. Therefore, the method and the apparatus can accurately distinguish an active voice and an inactive voice.

Abstract: A method for detecting an audio signal and an apparatus, where the method includes determining a segmental signal-to-noise ratio (SSNR) of an audio signal in response to the audio signal being an unvoiced signal, reducing a reference voice activity detection (VAD) decision threshold to obtain a reduced VAD decision threshold, and comparing the SSNR with the reduced VAD decision threshold to determine whether the audio signal is an active signal.

Abstract: An encoder includes a signal detection circuit and a signal encoding circuit. The signal encoding circuit is configured to encode the Nth-frame downmixed signal when the signal detection circuit detects that an Nth-frame downmixed signal includes a speech signal, or when the signal detection circuit detects that the Nth-frame downmixed signal does not include a speech signal, encode the Nth-frame downmixed signal when the signal detection circuit determines that the Nth-frame downmixed signal satisfies a preset audio frame encoding condition, or skip encoding the Nth-frame downmixed signal when the signal detection circuit determines that the Nth-frame downmixed signal does not satisfy a preset audio frame encoding condition.

Abstract: A signal encoding method and device are disclosed. The method includes, when an encoding manner of a previous frame of a currently-input frame is a continuous encoding manner, predicting a comfort noise that is generated by a decoder according to the currently-input frame when the currently-input frame is encoded into an SID frame, determining an actual silence signal, determining a deviation degree between the comfort noise and the actual silence signal, determining an encoding manner of the currently-input frame according to the deviation degree, and encoding the currently-input frame according to the encoding manner of the currently-input frame. It is determined, according to the deviation degree between the comfort noise and the actual silence signal, that the encoding manner of the currently-input frame is the hangover frame encoding manner or the SID frame encoding manner, which can save communication bandwidth.

Abstract: An image deployment method includes obtaining a configuration policy for a container, where the configuration policy for the container includes an autoscaling policy or a replication control policy. The autoscaling policy includes a first image identifier, a maximum quantity of containers corresponding to the first image identifier that can be deployed, and a quantity of currently deployed containers corresponding to the first image identifier. The replication control policy includes a second image identifier and a quantity of containers corresponding to the second image identifier that are expected to be deployed. The method determines an identifier of a to-be-deployed image according to the configuration policy for the container.

Abstract: The disclosure provides a method and an apparatus for detecting a voice activity in an input audio signal composed of frames. A noise attribute of the input signal is determined based on a received frame of the input audio signal. A voice activity detection (VAD) parameter is derived based on the noise attribute of the input audio signal using an adaptive function. The derived VAD parameter is compared with a threshold value to provide a voice activity detection decision. The input audio signal is processed according to the voice activity detection decision.
