Voice Recognition Headset Pairing via Acoustic Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless headset setup methods are inadequate, particularly for devices with limited user interfaces, as they rely on default passcodes that can be compromised or forgotten, and require manual entry of pairing information, which is impractical for devices like cordless telephony base adapters and 802.11 APs.
Innovation Solution
Integration of a voice recognition module into the headset, allowing users to input pairing information verbally through voice prompts and recognition, eliminating the need for additional buttons, keypads, or displays, and enabling secure connection setup with voice synthesis and recognition technology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a default passcode is used for pairing, then the setup process is simplified, but security is compromised and the passcode may be forgotten or hijacked
Solution Approach 1:
The headset performs self-configuration by automatically initiating pairing sequences and displaying passcode information without requiring user intervention on the base station. The voice prompts guide the user through the process, and the system automatically handles the technical pairing operations.
Solution Approach 2:
The patent replaces manual mechanical input methods (keyboards, displays, buttons) with acoustic fields - voice prompts for output and voice recognition for input. This substitution eliminates the need for physical interfaces on the base station and enables user-friendly pairing.
2Adaptability or versatility
If additional buttons and display are added to the headset for pairing, then pairing functionality is improved, but device complexity, size, and cost increase
Solution Approach 1:
The headset's existing voice recognition module is enhanced to perform multiple functions: it not only recognizes commands but also generates and processes pairing passcodes, displays pairing information, and manages the entire pairing sequence. This multi-functionality eliminates the need for separate dedicated pairing hardware.
Solution Approach 2:
The patent replaces mechanical input/output interfaces (buttons, display, keypad) with acoustic interfaces. The voice recognition module handles both input (user commands) and output (voice prompts), eliminating the need for physical buttons and displays on the headset for pairing operations.
3Reliability
If manual passcode entry is required on the base adapter, then pairing security is improved, but ease of operation deteriorates for users without keyboards
Solution Approach 1:
The patent replaces mechanical keyboard input with acoustic voice input. The base station displays passcode information via visual output, and the user enters the passcode by speaking it into the headset's microphone, which captures and processes the voice command to complete the pairing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables secure and user-friendly wireless headset pairing by allowing voice input of access point parameters, enhancing security and usability by eliminating the need for physical interfaces, thus simplifying the connection process and reducing costs.
Implementation Method 1
a voice recognition module, either as a small circuit board or as additional software running on an existing processor, is added to the headset
Implementation Method 2
voice synthesis means for issuing voice prompts
Data Source
AI summary
A wireless local area network system and a headset for the system. The headset uses voice input information to set up parameters needed to connect the headset to the corresponding access point and then start the connection process. When the connection fails or succeeds an appropriate voice prompt or visible signal tells the user the headset's connection status.
