Voice Print Matching for Process Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice assistant technologies in electronic devices lack the ability to ensure that only the user who initiated a process can stop or change it, leading to frustration when multiple users can control the device with voice commands, causing unintended process cessation or modification.
Innovation Solution
The implementation of a method where an electronic device captures and stores voice characteristics for process initiation commands, requiring matching voice characteristics for subsequent process cessation or modification commands, ensuring that only the original user can stop or change the process, and ignoring non-matching commands until the process is completed or timed out.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice assistant capabilities are added to electronic devices to enable voice control, then ease of operation is improved, but reliability deteriorates because multiple users can accidentally control the device and cause unintended process cessation or modification
Solution Approach 1:
The system performs preliminary action by capturing and storing voice characteristics at the moment a process is initiated. This stored voice print serves as a reference for subsequent verification, ensuring that only the original user can control the process. The preliminary capture of voice data before the process runs creates a baseline for authenticating future control commands.
Solution Approach 2:
The system implements feedback by continuously comparing the voice characteristics of incoming control commands against the stored voice print from the process initiation. This real-time verification feedback mechanism determines whether to execute or reject control commands, ensuring that only authenticated users can modify or stop processes they initiated.
2Reliability
If voice characteristics verification is implemented for process control, then reliability is improved by preventing false commands, but device complexity increases due to additional verification steps
Solution Approach 1:
The system uses copying by creating a digital replica (voice print) of the user's voice characteristics during process initiation. This copied voice template is then used for verification without requiring the original physical presence of the user, simplifying the verification process while maintaining security. The voice print serves as a reusable copy for authentication purposes.
3Reliability
If strict voice matching is required for all process control commands, then reliability is improved by preventing unauthorized control, but ease of operation deteriorates due to additional verification requirements
Solution Approach 1:
The verification of voice characteristics is performed as a preliminary action before executing any process control command. By pre-capturing the authorized user's voice print and establishing it as the authentication baseline, the system enables rapid verification during command execution without requiring complex real-time analysis, thus maintaining both security and operational efficiency.

AI summary
An electronic device includes one or more sensors and one or more processors. The one or more sensors receive a first audio input defining a process initiation command and initiate, in response to the process initiation command, a process. Thereafter, the one or more sensors receive a second audio input defining a process cessation command. The one or more processors determine whether one or more substantially matching audio characteristics are present in both the first audio input and the second audio input. Where they are absent from one of the first audio input or the second audio input, the one or more processors ignore the process cessation command and continuing the process. Where they are present, the one or more processors cease the process in response to the process cessation command.
