Dynamic Color Ringback Tone Generation via Text-to-Speech
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional color ringback tone systems provide only pre-selected, static audio messages to callers during the ringing state of a call, lacking personalization and real-time information.
Innovation Solution
Integration of text-to-speech technology with color ringback tones and caller-ID services to dynamically generate personalized audio messages, such as voicemail status, by converting text messages into spoken audio signals and playing them during the ringing state, potentially superimposed on traditional ringing tones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pre-selected static audio messages are used in color ringback tone systems, then device complexity is reduced and ease of operation is improved, but adaptability and information freshness deteriorate
Solution Approach 1:
The system transitions from static pre-selected audio messages to dynamic real-time generated audio messages. The media server dynamically generates personalized audio messages during the ringing state by converting text information about the caller into speech, allowing the content to adapt to each specific caller while maintaining ease of operation through automated processes.
Solution Approach 2:
The system uses automated text-to-speech conversion and caller identification services to generate personalized messages without manual intervention. The media server automatically retrieves caller information, converts it to audio format, and plays it during the ringing state, eliminating the need for manual message selection while maintaining operational simplicity.
2Adaptability or versatility
If real-time dynamic audio message generation is implemented, then adaptability and information freshness are improved, but device complexity and processing requirements worsen
Solution Approach 1:
The media server performs multiple functions: it handles traditional media playback, generates dynamic audio messages through text-to-speech conversion, retrieves caller identification information, and manages the ringing state. By consolidating these diverse functions into a single multi-functional platform, the system achieves high adaptability without proportionally increasing overall system complexity.
Solution Approach 2:
The patent introduces a media server as an intermediary component that bridges the gap between simple ringing tone generation and complex real-time message customization. This intermediary handles the complexity of text-to-speech conversion and caller information retrieval, shielding the rest of the system from complexity while enabling adaptive personalized messaging.
3Adaptability or versatility
If caller identification services are integrated, then personalization capability is improved, but information processing time and system complexity worsen
Solution Approach 1:
The system retrieves caller identification information during the ringing state, which occurs before the call is answered. By performing the information retrieval and audio generation in advance during the natural ringing period, the system provides personalized messages without adding noticeable delay to the call establishment process.
Solution Approach 2:
The audio message generation and playback occur continuously during the ringing state, utilizing the existing time period when the call is being established. This continuous utilization of the ringing state ensures that personalization is achieved without extending the overall call setup time, as the useful action of providing information fills the existing time window.

Data Source
AI summary
A system and method for providing dynamically generated information to a caller during the ringing state of a telephone call. In one example, color ringback tones may be used in conjunction with text-to-speech technology and caller ID services to provide personalized audio messages. These messages may be generated in real time and may include information that may be useful to the caller, such as up-to-date status information (e.g., the status of the caller's voicemail inbox), news or other information.
