IoT Voice Broadcast Device Local Storage for Timely Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice broadcast methods in IoT devices face delays and hardware upgrade requirements for timely and accurate voice information delivery, leading to inefficiencies in broadcasting due to weak hardware and the need for continuous updates.
Innovation Solution
Pre-delivering voice information to IoT devices, allowing them to locally store and retrieve voice content using identification information, thereby avoiding real-time downloads and eliminating the need for hardware upgrades when updates occur.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If voice information is downloaded in real-time from the server, then the voice content can be updated, but download delays occur and hardware upgrades are required
Solution Approach 1:
The patent pre-delivers voice information from the server to the IoT device in advance and stores it locally in the device's memory. When a voice broadcast condition is met, the device retrieves the pre-stored voice content locally without needing to download it in real-time, thereby eliminating download delays and improving broadcast timeliness.
2Productivity
If voice information is stored locally in IoT devices, then download delays are eliminated, but device memory capacity is required
Solution Approach 1:
The patent delivers specific voice information tailored to each IoT device's local characteristics and requirements. The server determines which voice content should be stored in each device's memory based on device-specific parameters, ensuring that each device has the appropriate voice information locally available without unnecessarily occupying storage capacity.
3Reliability
If voice content is updated on the server, then accurate information is maintained, but hardware upgrades are needed for devices to access updated content
Solution Approach 1:
When voice information is updated on the server, the system pre-delivers the updated voice content to IoT devices and stores it locally in their memory. This allows devices to access updated voice information without requiring hardware upgrades, as the updated content is already available in their local storage.
4Loss of time
If voice information is pre-delivered to devices, then broadcast timeliness is improved, but network bandwidth is consumed
Solution Approach 1:
The server delivers voice information specifically tailored to each IoT device based on its local characteristics and broadcast conditions. This targeted delivery approach ensures that each device receives only the necessary voice content, optimizing network bandwidth utilization while achieving timely local retrieval and broadcast.

AI summary
A voice broadcast method includes: acquiring at least one piece of voice information; delivering the at least one piece of voice information to a voice broadcast device, wherein, the at least one piece of voice information includes voice identification information and a voice content; determining a first voice content to be broadcast by the voice broadcast device, wherein the first voice content is included in the at least one piece of voice information stored at the voice broadcast device; and sending, to the voice broadcast device, a first voice identification information corresponding to the first voice content, wherein the first voice identification information is used by the voice broadcast device to obtain the first voice content stored at the voice broadcast device, and to broadcast the first voice content when a preset voice broadcast condition is met.
