Voice Dictation Gesture Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current voice dictation systems face challenges in adapting to natural speech patterns, particularly in differentiating between words that can be commands or punctuation, leading to unintended command execution when users pause during speech.
Innovation Solution
A system and method that utilize a microphone and gesture detection sensor to process audio waveforms in two modes, where a detected touchless gesture with matching timestamp allows for alternate processing of audio waveforms, enabling differentiation between command and punctuation meanings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice dictation systems process full spoken word strings as text and look for pauses to determine the end of text, then hands-free processing is enabled, but unintended commands are executed when users pause to collect thoughts
Solution Approach 1:
A gesture detection sensor acts as an intermediary between the user and the voice processing system. When a user performs a specific gesture (such as a hand wave or fist clench), the system interprets this as a command delimiter, allowing the user to explicitly indicate where one command ends and the next begins, thereby preventing misinterpretation of pauses as command delimiters
Solution Approach 2:
The system dynamically switches between two processing modes: a first mode for processing text from voice dictation and a second mode for processing commands. This dynamic mode switching allows the system to adapt its interpretation of spoken words based on the current operational context, enabling flexible handling of both text generation and command execution
2Device complexity
If the system processes audio waveforms in a single mode, then processing is simple, but the system cannot differentiate between words that are commands versus punctuation
Solution Approach 1:
The system implements dynamic mode switching between a first processing mode (for text) and a second processing mode (for commands). The mode is determined by detecting specific gestures from the gesture detection sensor, allowing the system to adapt its processing behavior based on the user's intended action, thereby achieving precise word meaning differentiation without permanently increasing system complexity
Solution Approach 2:
The processing system is segmented into distinct functional modes: a first mode for processing voice dictation text and a second mode for processing commands. This segmentation allows each mode to be optimized for its specific function, with the gesture sensor providing the switching mechanism that separates the processing tasks

AI summary
Systems and methods for switching between voice dictation modes using a gesture are provided so that an alternate meaning to a dictated word may be applied. The provided systems and methods time stamp detected gestures and detected words from the voice dictation and compare the time stamp at which a gesture is detected to the time stamp at which a word is detected. When it is determined that a time stamp of a gesture approximately matches a time stamp of a word, the word may be processed to have an alternate meaning, such as a command, punctuation, or action.
