Solution Overview

Problem

Vehicles have limited voice options for communication, often allowing only language, male/female, and accent selections, which may not cater to individual occupant preferences or responsiveness.

Innovation Solution

An avatar system that identifies vehicle occupant scenarios and selects a voice profile from a library, using AI to determine a voice model based on occupant responsiveness, allowing customization through voice sampling and manual selection of characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a limited selection of voice options (language, male/female, accent) is provided, then the system complexity is reduced and ease of operation is improved, but adaptability to individual occupant preferences and responsiveness is worsened

Engineering Contradiction:
Improveease of voice selectionVSAvoidadaptability to occupant preferences
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts voice profile selection based on detected driving scenarios and occupant responsiveness levels. Voice profiles are not statically assigned but adapt in real-time to changing conditions, allowing the system to maintain simplicity while improving adaptability through automated dynamic selection.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system performs self-service by automatically selecting appropriate voice profiles without requiring manual configuration by the occupant. The avatar communication system monitors occupant responsiveness and autonomously adjusts voice characteristics, eliminating the need for complex user setup while achieving personalized communication.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If multiple voice profiles are introduced to cater to individual preferences, then adaptability to occupant responsiveness is improved, but device complexity increases

Engineering Contradiction:
Improveadaptability to occupant responsivenessVSAvoidcomplexity of voice profile management
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system implements feedback mechanisms by monitoring occupant responsiveness to different voice profiles and using this information to automatically select optimal voices. This closed-loop approach allows the system to manage multiple voice profiles effectively, as the feedback-driven selection process automates what would otherwise require complex manual configuration.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The avatar acts as an intermediary between the vehicle's communication system and the occupant, managing the complexity of voice profile selection. Rather than exposing the full complexity of multiple voice profiles to the user, the avatar mediates by automatically selecting appropriate profiles based on detected scenarios and responsiveness, simplifying the user experience while maintaining adaptability.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If voice profiles are manually configured, then adaptability to specific preferences is improved, but ease of operation is worsened due to setup complexity

Engineering Contradiction:
Improvecustomization to preferencesVSAvoidease of voice configuration
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system eliminates manual configuration requirements by implementing self-service functionality. The avatar communication system automatically detects occupant preferences and responsiveness through monitoring interactions, then autonomously configures and selects appropriate voice profiles without requiring user setup, thereby maintaining customization while improving ease of operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary actions by pre-configuring voice profiles based on initial occupant interactions and scenario detection. Rather than requiring manual setup at installation, the system proactively configures appropriate voice profiles through automated monitoring and analysis of occupant responsiveness, preparing the personalized communication experience in advance without user intervention.

Inventive Principle:
Principle #10Preliminary action

AI summary

A method, computer program product, and computer system for identifying, by a computing device, a scenario of a plurality of scenarios associated with an occupant of a vehicle. A voice profile of an avatar may be determined for the scenario of the plurality of scenarios associated with the occupant of the vehicle. The voice profile of the avatar determined for the scenario of the plurality of scenarios associated with the occupant of the vehicle may be selected, wherein the voice profile of the avatar may be selected from a plurality of voice profiles. Audio may be provided to the occupant of the vehicle using the voice profile of the avatar based upon, at least in part, identifying the scenario of the plurality of scenarios associated with the occupant of the vehicle.
