ARS Call Voice-to-Text Conversion for Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During automatic response system (ARS) calls, users often struggle to remember voice guidance content or have difficulty hearing due to diminished hearing, requiring repeated listens or calls to understand the information displayed on electronic devices, which lack text conversion and display capabilities during phone calls.
Innovation Solution
An electronic device with a communication unit, audio unit, input unit, controller, and display unit that determines if a call is an ARS call, converts voice data to text, and displays the text, allowing for language translation and user input handling to improve accessibility and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice data is displayed during ARS calls, then information accessibility is improved, but device complexity increases due to adding text conversion and display capabilities
Solution Approach 1:
The display unit serves dual purposes: displaying traditional call information and converting voice data to text for ARS calls. The controller identifies ARS calls and activates text conversion functionality only when needed, allowing one component to perform multiple functions without permanently increasing device complexity
Solution Approach 2:
The controller acts as an intermediary that receives voice data from the audio unit, determines whether it's an ARS call, converts voice to text using speech recognition, and displays the result on the display unit. This intermediary processing enables information accessibility while managing complexity through conditional activation
2Ease of operation
If text display is added during phone calls, then usability for hearing-implied users is improved, but loss of time increases due to processing and display requirements
Solution Approach 1:
The controller preliminarily determines whether a call is an ARS call by analyzing voice characteristics or call parameters before initiating full text conversion. This preliminary classification allows the system to prepare for text display only when necessary, reducing unnecessary processing time
Solution Approach 2:
The system applies partial text conversion by displaying only relevant portions of voice guidance as text, or selectively converting only critical information segments. This partial action approach maintains usability for hearing-implied users while minimizing processing time and computational resources

AI summary
An electronic device and method for displaying phone call content are provided. The electronic device includes a communication unit configured to transmit and receive voice data during a phone call connection, an audio unit configured to input and output voice data, an input unit configured to receive a user input, a controller configured to determine whether a connected phone call corresponds to an automatic response system (ARS) phone call, and convert received voice data into text data when the connected phone call corresponds to the ARS phone call, and a display unit configured to display the converted text data.
