Telecommunication Gateway Voice Announcement Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telecommunication gateways lack the ability to effectively recognize and respond to typed voice announcements during connection setup or data transmission issues, leading to inefficiencies and errors in establishing or maintaining telecommunications connections.
Innovation Solution
A method where a gateway records and evaluates pause-tone information from voice announcements, using pattern recognition to identify specific patterns and trigger actions such as changing routing or activating/deactivating hardware/software, enabling early recognition and countermeasures for connection issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex voice recognition systems are used to accurately identify voice announcements, then recognition accuracy is improved, but processor power requirements and system complexity increase
Solution Approach 1:
The voice announcement recognition is segmented into distinct acoustic features (pause tones, word lengths, spacing patterns) that can be independently analyzed. This segmentation allows the gateway to recognize voice announcements by evaluating specific acoustic parameters rather than processing the entire voice signal, thereby reducing computational complexity while maintaining recognition accuracy.
Solution Approach 2:
The patent extracts only the essential acoustic features (pause-tone information, word length, spacing) from the voice announcement signal for evaluation. By taking out and analyzing only these critical features rather than the complete voice signal, the system achieves accurate recognition with reduced processor power requirements.
2Loss of information
If voice announcements are forwarded to the calling end system, then information completeness is improved, but connection establishment time increases due to additional transmission
Solution Approach 1:
The gateway performs preliminary evaluation of voice announcements by analyzing their acoustic features (pause tones, word lengths, spacing patterns) before forwarding them to the calling end system. This preliminary action allows the gateway to identify and filter relevant information, ensuring that only necessary voice announcements are transmitted, thereby reducing transmission time while maintaining information completeness.
Solution Approach 2:
The gateway uses feedback from the acoustic feature evaluation to determine whether and how to forward voice announcements. By analyzing pause-tone information and comparing it against stored patterns, the gateway can make intelligent decisions about information transmission, optimizing both information delivery and connection establishment time.

AI summary
The invention relates to a method for using voice messages in telecommunications connections. The method comprises the following steps: - routing a connection establishment or the data of a through-connected telecommunications connection from a calling end system (11, 12) over at least one first communication network (31, 32) to a gateway (40), which represents an interface between the first communication network (31, 32) and a second communication network (51, 52), - routing the connection establishment or the data of the through-connected telecommunications connection from the gateway (40) over at least the second communication network (51, 52) to a called end system (21-24), - recording a standardized voice message concerning the telecommunications connection, which is provided to be transmitted to the calling end system (1, 11, 12), in the gateway (4, 40), - evaluating the standardized voice message, and - taking an action concerning the telecommunications connection or the gateway (40) through the gateway (40) depending on the result of the evaluation performed. The invention further relates to a gateway for performing such a method.
