Solution Overview

Problem

Existing speech processing systems struggle with reconciling and managing multiple communications identifiers for the same individual across different contact lists, leading to inefficiencies and privacy concerns when users attempt to communicate.

Innovation Solution

A system that integrates speech recognition and natural language understanding to identify and consolidate multiple communications identifiers for a single individual, allowing users to block or set preferences at the profile level, ensuring seamless communication and privacy management across various modalities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple communications identifiers for the same individual are managed separately across different contact lists, then each identifier can be tracked independently, but communication efficiency decreases and privacy management becomes complex

Engineering Contradiction:
Improvecommunication efficiencyVSAvoidcontact list management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system merges multiple contact lists from different sources into a unified contact list, consolidating duplicate entries for the same individual. This integration allows the system to manage multiple communications identifiers (phone numbers, email addresses, etc.) for a single contact centrally, improving communication efficiency while reducing management complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The unified contact list serves multiple functions simultaneously: it stores and manages multiple identifiers for each contact, enables comprehensive blocking options, supports privacy management, and facilitates seamless communication across different modalities. This multi-functionality resolves the contradiction by making a single system handle what previously required multiple separate management approaches.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Object-affected harmful factors

If users block communications at the identifier level, then specific unwanted contacts can be prevented, but privacy is compromised by exposing which identifiers are being blocked

Engineering Contradiction:
Improveunwanted communications blockingVSAvoidprivacy information
Core Design Contradiction:
Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The system introduces a unified contact list as an intermediary layer between the user and multiple communications identifiers. When blocking is applied at the contact level rather than the identifier level, the system mediates by translating the block into appropriate actions across all identifiers associated with that contact. This protects user privacy by not exposing which specific identifiers are blocked, while still effectively preventing unwanted communications.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If speech processing systems maintain detailed contact information for accurate identification, then communication accuracy improves, but data privacy risks increase

Engineering Contradiction:
Improvecontact identification accuracyVSAvoidprivacy security risks
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The system segments contact information into essential identification elements (name, primary identifier) and optional detailed elements (multiple phone numbers, email addresses, etc.). By structuring the unified contact list to prioritize minimal necessary information for identification while organizing additional identifiers as supplementary data, the system maintains accurate contact identification while reducing privacy security risks through controlled information exposure.

Inventive Principle:
Principle #1Segmentation

AI summary

Techniques for using validated communications identifiers of a user's communications profile to resolve entries in another user's contact list are described. When a user imports a contact list, the contact list may include multiple entities related to the same person. The system may identify one of the entries in the contact list that corresponds to a validated communications identifier stored in another user's communications profile. The system may identify other validated communications identifiers in the other user's communications profile and cross-reference them against the entries of the contact list. If the system determines the contact list includes entries for the different validated communications identifiers of the other user, the system may consolidate the entries into a single entry associated with the other user.
