Voice Communication System for Hands-Free Call Initiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current voice communication systems are not user-friendly for individuals who cannot easily operate smartphones, such as young children, elderly people, and those with disabilities, as they require complex dialing procedures and technical knowledge to initiate calls.
Innovation Solution
A voice communication system that allows users to initiate calls using voice commands or natural language phrases, enabling easy call establishment and response, without the need for remembering phone numbers or contact data, and automatically handles call session setup and termination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional smartphone dialing procedures are used, then call functionality is available, but ease of operation deteriorates for children, elderly people, and those with disabilities
Solution Approach 1:
The patent replaces the mechanical dialing system (physical buttons and keypad) with an acoustic field-based system. Users speak natural phrases into the device, and the system uses acoustic signal processing to recognize and interpret the voice commands, automatically initiating calls without requiring manual button pressing or keypad input.
Solution Approach 2:
The system performs self-service by automatically processing the voice command, identifying the recipient, and initiating the call session without requiring user intervention for dialing or contact selection. The device autonomously handles the entire call initiation process based on the spoken phrase.
2Adaptability or versatility
If voice commands from predetermined lists are used, then call establishment is simplified, but adaptability deteriorates as users cannot initiate calls in natural language
Solution Approach 1:
The patent changes the parameter of voice input from predefined discrete commands to continuous natural language phrases. The system accepts variable phrasing such as 'call mom', 'dial 555-1234', or 'contact john' and processes them through acoustic signal analysis and natural language understanding, allowing flexible and adaptable call initiation.
Solution Approach 2:
The voice recognition system serves multiple functions: it identifies the recipient, extracts contact information, determines the appropriate action (call initiation), and handles various speech patterns. This multi-functional approach allows a single voice input mechanism to replace multiple complex interaction modes.

AI summary
A system and method for providing call sessions between personal communication devices (PCDs) of sender users and recipient users are described. The system includes one or more voice communication domains (VCDs) interacting with each other, and a cross-domain coordinator configured to coordinate interaction between the voice communication domains over the Global Communication Network. Each VCD includes PCDs associated with the corresponding users, and a voice communication server (VCS) deployed within the voice communication domain. The VCS is configured to control operation of the PCDs verbally by user voice commands, and to provide call sessions between a sender user and a recipient user within the same voice communication domain and between the users of different voice communication domains. Initiation of the call sessions can be carried out either by voice commands to the VCS of the system or by delivering a voice call proposal of the caller user for voice communication directly to the recipient in a natural manner.
