Household Appliance Voice Output Using Pre-Stored Speech Segments
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, making it difficult for visually impaired users and increasing production costs.
Innovation Solution
A method that pre-stores language segments in a persistent information object using position information for identification and retrieval, allowing for efficient generation and output of voice output, even with limited hardware capabilities, by utilizing a file system or database for data management and storage, and optionally leveraging remote processing for additional resources when 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 resources and production costs increase significantly
Solution Approach 1:
Speech segments are pre-recorded and stored in an information object before runtime. This allows the system to use simple retrieval and playback operations instead of complex real-time speech synthesis, enabling high-quality voice output with minimal hardware requirements.
Solution Approach 2:
Instead of generating speech through complex synthesis algorithms, the system creates and stores actual audio recordings (copies of human speech) that can be directly played back. This copying approach preserves the natural quality of speech while avoiding the computational complexity of synthesis.
2Adaptability or versatility
If speech synthesis methods are implemented in household appliances, then voice output capability is improved, but production outlay and expense increase
Solution Approach 1:
All speech content is pre-recorded and stored in the information object during manufacturing. This eliminates the need for expensive real-time speech synthesis hardware and software, significantly reducing production costs while maintaining voice output capability.
Solution Approach 2:
The system uses a simple, inexpensive data storage structure (information object) instead of costly speech synthesis engines. This approach prioritizes cost-effectiveness over computational complexity, making household appliances more affordable to produce.
3Adaptability or versatility
If extensive audio data is processed using complex speech synthesis methods, then flexible voice output is achieved, but data storage and processing requirements increase
Solution Approach 1:
Speech segments are pre-recorded and stored in compact form in the information object. This eliminates the need for large datasets and complex processing algorithms, reducing data storage requirements while maintaining voice output flexibility through selective retrieval of pre-recorded segments.
