Voice Output Device for Speech Recognition Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Natural language interfaces in electronic devices often fail to recognize operator utterances correctly, especially at a distance or when the operator has difficulty speaking, leading to reduced success in providing operation instructions via voice input.
Innovation Solution
An electronic device controlling system comprising a control device and a voice output device that transmits and receives operation instructions, allowing the voice output device to output voice commands recognizable by the electronic device, enabling operation instructions to be provided without direct voice input, even at a distance or with speech difficulties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If direct voice input is used for operation instructions, then operation flexibility is improved, but recognition accuracy deteriorates when operator is at a distance or has speech difficulties
Solution Approach 1:
The patent introduces a voice output device as an intermediary between the control device and the speech recognition-capable electronic device. This intermediary converts operation instructions into voice output that is transmitted to the electronic device, thereby maintaining operation flexibility while improving recognition accuracy by using a synthesized voice source instead of relying on the operator's direct voice input.
2Measurement precision
If voice output device is introduced to transmit operation instructions, then utterance recognition accuracy is improved, but device complexity increases
Solution Approach 1:
The voice output device performs multiple functions: it receives operation instructions from the control device, converts them into voice output, and transmits them to the speech recognition-capable electronic device. By consolidating these functions into a single device, the patent improves recognition accuracy while minimizing the increase in system complexity.
3Device complexity
If operator speaks directly to electronic device, then system simplicity is maintained, but success rate of instruction transmission deteriorates under adverse conditions
Solution Approach 1:
The voice output device serves as a mediator that generates standardized voice output for operation instructions. This intermediary approach maintains relative system simplicity while significantly improving the reliability of instruction transmission by using a controlled voice source that is less susceptible to adverse conditions such as distance or speech difficulties.

AI summary
An electronic device controlling system that provides an instruction via voice for an operation of a speech recognition-capable electronic device includes a control device and a voice output device capable of communicating with the control device. The control device includes a first input unit that receives, from an operator, a first input to which a first operation instruction for the speech recognition-capable electronic device is assigned; and a transmitter that, when the first input unit receives the first input, transmits, to the voice output device, first information for communication corresponding to the first operation instruction assigned to the first input. The voice output device includes a receiver that receives the first information for communication from the control device; and an output unit that, when the receiver receives the first information for communication, outputs a first voice for the first operation instruction based on the first information for communication.
