Voicemail Preview via Segmented Audio on Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing voicemail systems in cellular phone networks are inefficient due to slow data links and lengthy download times, making it impractical to navigate and manage voicemails, especially as the number of messages increases, and requiring users to listen to messages sequentially.
Innovation Solution
Implementing a VoIP phone system that allows mobile devices to access and preview voicemails using a limited bandwidth data channel by displaying a list of voicemails with preview portions, which are compressed audio files, enabling users to select and play short chunks of messages, thereby reducing latency and bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If users access entire voicemail messages through cellular phone systems, then complete message content is available, but download time becomes excessively long due to slow data links
Solution Approach 1:
The voicemail message is divided into two parts: a preview portion (first few seconds) that is downloaded and played immediately, and the remaining portion that is downloaded only if the user chooses to listen to the full message. This segmentation reduces the initial download time while preserving access to complete message content when needed.
Solution Approach 2:
Instead of downloading the entire voicemail message, the system downloads only a partial portion (the preview segment) initially. This partial action provides sufficient information for users to decide whether to download the full message, thereby reducing unnecessary data transfer and wait time.
2Loss of information
If the number of voicemail messages increases, then more communication information is available, but navigation time increases as all messages must be listened to in sequence
Solution Approach 1:
The system segments the voicemail listening process into two stages: quick preview of the first few seconds of each message to assess relevance, followed by optional full-message playback only for selected messages. This allows users to rapidly scan through multiple messages without committing to listening to each one completely.
Solution Approach 2:
The system performs preliminary action by downloading and playing the preview portion of each voicemail message before the user decides whether to download and listen to the full message. This preliminary assessment enables users to filter out unwanted messages quickly, reducing overall navigation time through large volumes of voicemails.
3Quantity of substance
If users frequently clear out voicemails to manage space, then storage capacity is maintained, but usage convenience decreases compared to email management
Solution Approach 1:
The system segments voicemail access into preview and full-listening modes, allowing users to manage their voicemail inbox more efficiently. Users can quickly preview multiple messages to identify which ones to keep or delete, rather than having to listen to entire messages before making decisions. This segmented approach makes voicemail management more similar to email management, where users can rapidly scan subjects and decide what to retain.
Data Source
AI summary
Previewing voice over internet protocol (VoIP) voicemail is disclosed. A request is sent for VoIP voicemail available to preview using a data channel associated with a cellular phone system. Information of voicemail available to preview and one preview portion for each of the voicemail available to preview are received. Information of voicemail available to preview is displayed. A selection of one of the available voicemails is received. A preview portion of the voicemail corresponding to the selection of one of the available voicemails is played.
