    Abstract: Aspects of fine-grained, dynamic noise pattern learning for voice applications include a vehicle, the vehicle having a body with a cabin. Embedded within the vehicle is a processor coupled to memory. The processor may be configured to embed multimodal data for environment and vehicle data. The embedded acoustic data may be from microphone-captured data in the cabin. The processor may concatenate the embeddings to form a latent vector characterizing the embeddings to thereby estimate a mean and variance of the latent vector using an adaptive time window. The processor may identify a noise type using the mean and variance of the latent vector, the noise type identification being fine-grained via the adaptive time window to accurately emulate vehicle noise.

    Abstract: A voiceprint module for in-vehicle voiceprint drift detection. The module may be configured for determining an archived voiceprint for an operator of a vehicle, generating a first real-time voiceprint according to in-vehicle utterances of the operator made while operating the vehicle, generating a first voiceprint deviation to quantify statistical distance between one or more probabilistic density functions associated with each of the first real-time and archived voiceprints, and updating one or more vocal characteristics of the archived voiceprint to generate an updated voiceprint in response to the first voiceprint deviation surpassing an update threshold.

    Abstract: The concepts include a user support system in the form of a microphone, a visual display arranged in a vehicle cabin, and a controller. The controller includes an instruction set that is executable to receive, via the microphone, a voice-based request from a user, and employ a virtual assistant to determine a user interaction in real time and to determine a specific intent for the voice-based request, including capturing metadata. A user interaction routine determines a user interaction parameter associated with the virtual assistant based upon the voice-based request from the user. A user sentiment analysis routine determines a user satisfaction parameter associated with the virtual assistant based upon the voice-based request from the user. The controller responds in real-time to the voice-based request based upon the user satisfaction parameter and the user interaction parameter that are associated with the virtual assistant.

    Abstract: A method for recognizing speech in a vehicle includes receiving speech at a microphone installed to a vehicle, and determining whether the speech includes a navigation instruction. If the speech includes a navigation instruction, the speech may be sent to a remote facility. After sending the speech to the remote facility, a local speech recognition result is provided in the vehicle to the user. The speech sent to the remote facility may be used to provide corrective action. A system for recognizing speech in a vehicle may include a microphone, and may be configured to determine a local speech recognition result from the speech command and determine when the speech command includes a navigation instruction. The system may further include a remote server in communication with the vehicle that receives a sample of the speech command from the speech recognition system when the speech command includes a navigation instruction.
