摘要： A sampler module may divide an audio signal into a series of sequential samples. A signal quality detector module may identify a consistent brick wall frequency of the audio signal spanning a plurality of the sequential samples at an outset of the audio signal and determine a signal treatment indication proportional to the brick wall frequency. A signal enhancer module may sequentially receive and analyze one or more sample components of the audio signal to identify lost parts of the audio signal in the one or more sample components of respective sequential samples, and generate, in accordance with the signal quality indication, a corresponding signal treatment for each of the one or more sample components of respective sequential samples having a corresponding identified lost part.

摘要： In at least one embodiment, an apparatus for enhancing speech prompts in a vehicle is provided. The apparatus includes an audio processor that is electrically coupled to a plurality of loudspeakers in a vehicle. The audio processor being programmed to provide entertainment data to the plurality of loudspeakers for playback in the vehicle and to receive a speech prompt indicative of only a spoken audio output to a driver in the vehicle. The audio processor is further programmed to mute the entertainment data that is played back on a first loudspeaker of the plurality of loudspeakers in response to the speech prompt and to provide the speech prompt to the first loudspeaker for playback to the driver in response to the speech prompt.

摘要： A sampler module divides an audio signal into a series of sequential samples. A signal quality detector module identifies, over a plurality of samples at an outset of the audio signal, a spectral variance of a first range of frequencies of the audio signal below a predetermined threshold frequency as being consistently greater than a spectral variance of a second range of frequencies of the audio signal above the predetermined threshold frequency and determines a signal treatment indication responsive to the identification. A signal enhancer module sequentially receives and analyzes one or more sample components of the audio signal to identify lost parts of the audio signal in the one or more sample components of respective sequential samples, and generates, in accordance with the signal treatment indication, a corresponding signal treatment for each of the one or more sample components of respective sequential samples having a corresponding identified lost part.
