Audio processing device and associated audio processing method
An audio processing device is disclosed. The audio processing device includes a filter and an output circuit. The filter is configured to receive an audio signal to generate a filtered audio signal, wherein the filter includes a plurality of parameters that are adjustable for changing a bandwidth, a center frequency or a gain of response of the filter. The output circuit is configured to receive the filtered audio signal to generate an output audio signal to a speaker. When the parameters of the filter are changed, the filter reduces changes in the audio signal caused by the parameters, and the output circuit continuously receives the filtered audio signal to generate the output audio signal for the speaker to play without interruption.

The equalizer circuit is arranged to receive an input signal, and process the input signal to generate an output signal. The first protection circuit is arranged to generate a first protection signal according to the output signal, the input signal, and a first processed signal. The second protection circuit is arranged to generate a second protection signal according to the input signal and a second processed signal. The first addition circuit is coupled to the first protection circuit and the second protection circuit, and is arranged to combine the first protection signal and the second protection signal to generate an equalizer output signal.
Altering audio to improve automatic speech recognition
Techniques for altering audio being output by a voice-controlled device, or another device, to enable more accurate automatic speech recognition (ASR) by the voice-controlled device. For instance, a voice-controlled device may output audio within an environment using a speaker of the device. While outputting the audio, a microphone of the device may capture sound within the environment and may generate an audio signal based on the captured sound. The device may then analyze the audio signal to identify speech of a user within the signal, with the speech indicating that the user is going to provide a subsequent command to the device. Thereafter, the device may alter the output of the audio (e.g., attenuate the audio, pause the audio, switch from stereo to mono, etc.) to facilitate speech recognition of the user's subsequent command.
