Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional headsets with adjustable microphones often experience incorrect positioning, leading to poor speech input reception, resulting in reduced productivity and errors in workflow operations due to manual adjustments that may drift or become misaligned during use.
Innovation Solution
A method and system that utilize a computing device and stepper motor to adjust the microphone's orientation based on feedback parameters such as confidence, vocabulary assistance, and node exit attempts, automatically moving the microphone to optimize its position relative to the user's mouth for clear speech input recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of microphone boom is used, then ease of operation is improved, but reliability deteriorates due to incorrect positioning and drift during use
Solution Approach 1:
The system uses speech recognition feedback parameters (confidence scores, vocabulary assistance counts, node exit attempts) to continuously monitor microphone positioning quality and automatically adjust the boom position to maintain optimal speech input reception
Solution Approach 2:
The microphone positioning system automatically adjusts itself based on speech recognition performance metrics without requiring manual intervention, using the speech recognition system itself to generate adjustment commands through the stepper motor
2Reliability
If automatic adjustment based on speech recognition feedback is implemented, then reliability of speech input reception is improved, but device complexity increases
Solution Approach 1:
The speech recognition system serves dual purposes: it processes user commands for workflow tasks and simultaneously evaluates microphone positioning quality through its feedback parameters, eliminating the need for separate sensing hardware
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated electromechanical system using a stepper motor controlled by software logic based on speech recognition metrics, transitioning from manual operation to automated control
3Device complexity
If microphone position is fixed, then device complexity is reduced, but productivity deteriorates due to incorrect positioning and need for repetition
Solution Approach 1:
The microphone boom transitions from a static or manually-fixed position to a dynamic position that automatically adapts to maintain optimal speech reception, adjusting in real-time based on speech recognition feedback during workflow tasks
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
The system ensures accurate and clear speech input reception by automatically adjusting the microphone's position, reducing errors and improving productivity by maintaining optimal alignment with the user's mouth, even during movement or task performance.
Implementation Method 1
cause a stepper motor to move the microphone from the first position to a second position
Data Source
AI summary
Example embodiments relating to the adjustment of a microphone attached to a headset are provided. The adjustable headset detects a microphone attached to the headset at a first position and receives one or more speech signal inputs from a user. The headset calculates a feedback parameter which includes a confidence parameter, a vocabulary assistance parameter, and a node exit attempt parameter. The headset determines a pass state in an instance in which the feedback parameter satisfies a feedback threshold, to maintain the microphone at the first position. The headset determines a fail state in an instance in which the feedback parameter fails to satisfy a feedback threshold, to cause a stepper motor to move the microphone from the first position to a second position relative the user.
