Multimodal SMS Platform Voice Text Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing SMS services lack seamless integration with advanced multimedia services, requiring expensive new devices and network capabilities, and do not inter-operate effectively with standard text messaging systems, limiting their accessibility and functionality.
Innovation Solution
A multimodal SMS mechanism that combines speech and text capabilities using standard wireless devices, employing a short message service center and a multimodal platform to store and identify messages with unique identifiers, allowing seamless integration with existing SMS services and enabling voice messaging, inter-working with MMS, voice mail, and instant messaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If new multimedia messaging services (MMS) are introduced to provide advanced messaging capabilities, then messaging functionality is improved, but device cost and network complexity increase significantly
Solution Approach 1:
The patent combines speech and text messaging capabilities into a unified SMS framework, allowing standard SMS devices to handle both modalities through a single service infrastructure rather than requiring separate MMS infrastructure
Solution Approach 2:
The invention enables standard SMS services to perform multiple functions by integrating speech recognition and text-to-speech capabilities, allowing the same SMS infrastructure to handle both traditional text messaging and voice messaging without requiring dedicated MMS hardware
2Adaptability or versatility
If new multimedia messaging services are deployed to enable voice and image messaging, then service capability is improved, but network infrastructure complexity increases
Solution Approach 1:
The patent introduces speech recognition and text-to-speech servers as intermediaries that translate between speech and text formats, allowing existing SMS network infrastructure to handle voice messaging without requiring direct voice transmission capabilities
Solution Approach 2:
The invention creates text representations of speech messages and speech representations of text messages, allowing the SMS network to transmit voice content as standardized text messages that can be routed through existing SMS infrastructure
3Measurement precision
If unique identification mechanisms are implemented for each message to enable seamless retrieval, then message identification accuracy is improved, but service resource consumption increases
Solution Approach 1:
The patent segments the message identification system into two parts: a reusable service identifier that identifies the type of message, and a unique message identifier that identifies the specific instance, allowing efficient retrieval without requiring entirely unique identifiers for every message type
Solution Approach 2:
The invention allows service identifiers to be reused across different messages and users, recovering and reusing identification resources rather than allocating new unique identifiers for each message, thereby reducing the total number of identification numbers required

AI summary
Methods for combining speech with existing text wireless Short Message Service (SMS) to create a multimodal SMS service are provided. A user of standard SMS text service is provided with a link within each message that allows adding or retrieval of a voice message associated with an SMS text message. A speech server in the wireless network may be used for recognition of voice commands, rendering of test into speech, and recording or playing back voice recordings. An automatic and unique identification of each message is created to allow retrieval of the message without manually selecting the message. Additional services include message lists, integration with voicemail systems, image and video messages, cross-functional applications with Multimedia Messaging Services (MMS) and Enhanced Message Services (EMS), and extensions of the combination of voice with text SMS to other computing devices such as PDAs and PCs.
