Solution Overview

Problem

Existing translation technologies require users to listen to spoken language while reading text, which is cumbersome and inefficient.

Innovation Solution

An audio system that spatializes original and translated voice signals, allowing them to be presented sequentially or simultaneously, enabling users to hear multiple languages without interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If users listen to spoken language while reading text, then translation information is provided, but user convenience deteriorates and operation becomes cumbersome

Engineering Contradiction:

Improvetranslation information deliveryVSAvoiduser convenience

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The patent replaces the mechanical/visual system of reading text with an acoustic system of listening to speech. The translation output is converted from text form to speech form through text-to-speech synthesis, allowing users to receive translation information auditorily rather than visually, thereby improving ease of operation while maintaining complete information delivery.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces speech as an intermediary medium between the translation system and the user. Instead of directly presenting translated text to the user, the system converts the text to speech through text-to-speech synthesis, creating an auditory intermediary that delivers the same information in a more convenient format.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If multiple voice signals are presented simultaneously, then communication efficiency improves, but signal interference increases

Engineering Contradiction:

Improvecommunication efficiencyVSAvoidsignal interference

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent separates multiple voice signals into different spatial dimensions using audio spatialization technology. Instead of mixing multiple voices in the same auditory space causing interference, the system positions original and translated voices at different spatial locations, allowing users to distinguish and process multiple signals simultaneously without interference.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent segments the auditory space into distinct spatial zones for different voice signals. By spatializing the audio output, the system divides the monolithic audio stream into separable spatial components, enabling users to selectively attend to different voices based on their spatial position rather than struggling with overlapping signals.

Inventive Principle:

Principle #1Segmentation

AI summary

A method or an audio system for translation with audio spatialization. The audio system transcribes a first voice signal into first text in a first language. The first text is translated into second text in a second language. The audio system generates a second voice signal that corresponds to the second text in the second language. The first voice signal and the second voice signal are spatialized. The audio system presents the spatialized first voice signal and second voice signal to a user at a same time.
