A method at an infrastructure unit of signaling a presence of a vulnerable road user, the method including receiving at least one report from a sensor unit, the at least one report indicating the presence of the vulnerable road user; composing a message indicating the presence of the vulnerable road user; and transmitting the message to road users proximate the infrastructure unit on a channel.

Method and apparatus for providing road user alerts

A system and method that enhances spoken utterances and provides entertainment by capturing one or more microphone signals containing echo and decomposing the one or more microphone signals into a plurality of signal paths through a synthesizer that adds or makes non-linear modifications to some of the captured one or more microphone signals. The system and method and estimates multiple echo paths from each of the one the one or more microphones. The system and method processes the captured microphone signals in response to the estimated plurality of echo paths by subtracting the echo contributions of each of the plurality of echo paths from the captured one or more microphone signals. The system and method also provide signal separation and post processing functions that renders speech recognition gaming applications.

Voice interface and vocal entertainment system

A system and method for a vehicular alert that detects a person or animal, determines an environmental noise level from a microphone, determines an alert characteristic response to detection of the person or animal, and emits the alert signal based on the determined alert characteristic, which is adjusted based on the environmental noise level. The alert signal draws the attention of the person or animal to the vehicle to reduce the likelihood of an accident.

System and method for vehicular alert

A digital audio system, which may be an integrated audio system of a vehicle, includes a microphone, a loudspeaker, and a processor. The processor is operable to modify digital audio signals based on tuning parameters to compensate for acoustic characteristics of the environment. The processor is further operable to detect that modification of digital audio signals based on the tuning parameters cannot fully compensate for the acoustic characteristics of the environment. The detection is based on an audio signal corresponding to audio captured from the environment and/or on the values of the tuning parameters. Upon detecting that modification of digital audio signals based on the tuning parameters cannot fully compensate for the acoustic characteristics of the environment, an indication is provided that the audio system should be calibrated to adjust the tuning parameters to the environment. Related methods and computer-readable media are also disclosed.

System and method for detecting and indicating that an audio system is ineffectively tuned

A method and system for adaptive noise masking powertrain noise in a vehicle is described. The method comprises: determining frequency and amplitude characteristics of the powertrain noise; determining amplitude characteristics of background noise in the vehicle; dynamically generating a masking audio signal based on the determined characteristics of the powertrain noise and background noise; and outputting the masking audio signal in a cabin of the vehicle. The system includes: a processor; a memory storing processor-executable instructions that, when executed, cause the processor to determine frequency and amplitude characteristics of the powertrain noise and to determine amplitude characteristics of background noise in the vehicle; a masking noise generator for dynamically generating a masking audio signal based on the determined characteristics of the powertrain noise and background noise; and one or more vehicle cabin loudspeakers for receiving and outputting the masking audio signal in a cabin of the vehicle.

Adaptive noise masking method and system

A method and system of fault detection for an alert generation system. In the audio alert generation system, a stored digital alert audio file is selected to be processed to generate an analog audio signal to drive a speaker. An alert fault detection system obtaining a signal from the audio alert generation system, converts the obtained signal to a digitally-formatted obtained audio signal, detects a fault in the audio alert generation system by comparing the digitally-formatted obtained audio signal with the stored digital alert audio file, and triggers a fault indicator.

Alert fault detection system and method

A multimodal system and process processed one or more sensor signals and extracts features from the one or more sensor signals through a spatiotemporal correlation between consecutive frames of an image or video sequence. The multimodal system and process determines the movement and direction of the features through an image subtraction, or a coherence measure and synthesizes a musical instrument signal in response to the detected movement and direction or the triggers. The imaginary musical instrument signal is added to an infotainment signal within a vehicle.

Three-dimensional simulation system

A system and method for pedestrian alert that derives a pedestrian path representing a projected path for a pedestrian, derives a vehicle path representing a projected path for a motor vehicle, determines an intersection of the pedestrian path and the vehicle path, determines alert characteristics responsive to the determined intersection, and generates an alert that is emitted from the vehicle responsive to the determined alert characteristics. The system and method for pedestrian alert may be built, installed or implemented in a motor vehicles that is operated in environments where the motor vehicle may be in close proximity to pedestrians. The system and method for pedestrian alert mitigates the likelihood of a collision between the motor vehicle and a pedestrian by emitting an alert that may draw the attention of the pedestrian to the presence of the motor vehicle.

System and method for pedestrian alert

A system and method that enhances spoken utterances by capturing one or more microphone signals. The system and method estimates a plurality of echo paths from each of the one or more microphone signals and synthesizes a speech reinforcement signal in response to and corresponding to the one or more microphone signals. The system and method concatenates portions of the synthesized reinforcement signal with the captured microphone signals and processes the captured microphone signals in response to the estimated plurality of echo paths.

Synthetic speech for in vehicle communication

A system and method for processing an audio signal captured from a microphone may reproduce a known audio signal with an audio transducer into an acoustic space. The known audio signal may include content from one or more audio sources. A microphone audio signal may be captured from the acoustic space where the microphone audio signal comprises the known audio signal and one or more unknown audio signals. Processing control information may be accessed. The known audio signal may be reduced in the microphone audio signal responsive to the processing control information where the processing control information indicates one or more characteristics of a downstream audio processor that processes the microphone audio signal.

A system and method for synthesizing an engine sound may receive one or more vehicle operational data signals. One or more tone parameters associated with a Shepard tone generator may be modified responsive to the one or more vehicle operation data signals. A Shepard tone may be generated responsive to the modified one or more tone parameters. The Shepard tone may be reproduced using one or more audio transducers.

A system and method for speech reinforcement may determine the spatial location of an audio source and the spatial location of a listener. An audio signal generated by the audio source may be captured. The spatial location, relative to the listener, of two or more audio transducers that emit a reinforcing audio signal to reinforce the audio signal may be determined. The captured audio signal, responsive to the spatial location of the audio source, the spatial location of the listener and the spatial location of the two or more audio transducers to generate the reinforcing audio signal, such that, when emitted by the two of more audio transducers, the listener perceives a source of the reinforcing audio signal to be spatially located in substantially the spatial location of the audio source thereby reinforcing the audio signal.
