Voice Identification for Incoming Call Filtering

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for filtering harassing incoming calls are not adaptable to all calling scenarios, particularly when users cannot view their mobile phone screen, leading to disturbances from malicious calls.

Innovation Solution

Integration of voice play technology with incoming call identification, where voice identification information is determined and audibly played for the user, allowing them to recognize identification tags even when the screen cannot be viewed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If identification tags are used to filter harassing calls, then filtering effectiveness is improved, but adaptability to all calling scenarios deteriorates

Engineering Contradiction:

Improvefiltering effectivenessVSAvoidadaptability to calling scenarios

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces voice play technology as an intermediary between the identification tag system and the user. Instead of directly displaying tags on the screen, the system converts tag information into audible voice prompts that can be heard through speakers or headphones, enabling the filtering system to work effectively in scenarios where the user cannot view the screen.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the visual display mechanism (screen) with an acoustic mechanism (voice play). By substituting the visual interface with audio output, the system maintains filtering effectiveness while extending adaptability to scenarios such as driving, cooking, or other situations where visual attention is occupied.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Object-affected harmful factors

If users cannot view mobile phone screen, then safety is improved, but ability to identify incoming calls deteriorates

Engineering Contradiction:

Improvedisturbance from malicious callsVSAvoididentification tag information

Core Design Contradiction:

Object-affected harmful factorsVSLoss of information

Solution Approach 1:

Voice play technology serves as an intermediary that transfers identification information from the visual domain to the auditory domain. The system extracts identification tags, converts them into voice prompts, and plays them through the audio output device, allowing users to receive call identification information without needing to view the screen.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent transitions the information delivery channel from two-dimensional visual display to one-dimensional audio output. By changing the dimension of information presentation from visual to acoustic, the system enables users to perceive identification information through hearing rather than sight, resolving the conflict between screen safety and information accessibility.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

The present disclosure proposes a method for incoming call reminder, including: when receiving an incoming call, determining (101) voice identification information of the incoming call according to number information of the incoming call; and playing (102) the voice identification information of the incoming call for a user. In the present disclosure, when the voice identification information carries the identification tag information corresponding to the number information of the incoming call, a user may obtain the identification tag of the incoming call even in a calling scenario where it is inconvenient for a user to view the screen of a mobile phone.
