Method for producing acoustic speech output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for generating acoustic voice output in household appliances, such as food processors, are technically complex and expensive, requiring significant hardware resources that are often not feasible in these devices, leading to reduced operational comfort and difficulty for visually impaired users.
Innovation Solution
A method that pre-stores voice segments in a persistent information object using position information for identification and retrieval, allowing for efficient generation of voice output even with limited hardware capabilities, utilizing a file system or database for data management and storage, and enabling local or remote identification and generation of speech segments as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If modern text-to-speech systems are used for speech synthesis, then high-quality and flexible voice output is achieved, but hardware requirements and production costs increase significantly
Solution Approach 1:
The patent segments the speech output into pre-recorded voice segments stored in an information object, rather than generating speech synthetically in real-time. This segmentation allows the system to use simple playback functionality instead of complex text-to-speech synthesis hardware, resolving the contradiction between voice quality and hardware complexity.
Solution Approach 2:
The patent applies preliminary action by pre-recording and storing voice segments in an information object before runtime. The system identifies and retrieves relevant segments based on position information during operation, eliminating the need for complex real-time speech synthesis while maintaining high-quality voice output.
2Ease of operation
If speech synthesis methods are implemented in household appliances, then operational comfort and accessibility are improved, but production outlay and expense increase
Solution Approach 1:
The patent uses copying by storing pre-recorded voice segments in an information object that can be efficiently retrieved and played back. This approach copies actual human speech recordings rather than synthesizing them, providing natural-sounding voice output with minimal hardware requirements, thus improving ease of operation without increasing production costs.
3Adaptability or versatility
If voice segments are stored in a distributed manner, then flexibility is maintained, but management effort and retrieval complexity increase
Solution Approach 1:
The patent merges multiple voice segments into a single information object with an organized structure. Position information within this unified structure enables efficient identification and retrieval of specific segments without the overhead of managing distributed files, reducing data management complexity while maintaining full adaptability.
