Patent number: 11528358Abstract: Concepts and technologies are disclosed herein for communications network security for handling proxy voice calls that employ a voicebot. According to one aspect disclosed herein, a call handling system can intercept, from a communications network, a call request that is directed to a called target device. The call handling system can determine that the call request was generated by a voicebot on behalf of a user equipment. The call handling system can suspend the call request from being routed to the called target device. The call handling system can generate a voicebot confirmation request that identifies the voicebot and the user equipment. The call handling system can provide the voicebot confirmation request to the called target. The call request can be suspended while the voicebot confirmation request is provided to the called target device.Type: GrantFiled: November 23, 2020Date of Patent: December 13, 2022Assignee: AT&T Intellectual Property I, L.P.Inventors: Miranda Huet, James Pratt, Eric Zavesky, Gregory Edwards

Patent number: 11522993Abstract: A call analytics system and associated methods that can be used to rapidly analyze call data and provide conversational insights. The call analytics system receives audio call data of a phone call between a customer and an agent of a business, and converts the call data into one or more messages for handling by a distributed stream-processing platform. In some embodiments, the stream-processing platform is the Apache Kafka platform. The distributed platform processes the messages and communicates with various software modules to generate a variety of conversational insights. When processed by a stream-processing platform, certain analyses can occur in parallel which allows conversational insights to be provided to the businesses shortly (e.g., within seconds) after the call data is received.Type: GrantFiled: December 21, 2020Date of Patent: December 6, 2022Assignee: Marchex, Inc.Inventors: William Li, Michael Kunugiyama

Patent number: 11522994Abstract: Aspects of the disclosure relate to voiceprint tracking and anomaly detection. A computing platform may detect voice information from a call management system. The computing platform may establish voiceprints for employees and clients of an enterprise. The computing platform may detect a call between an employee and a caller attempting to access a client account. The computing platform may identify a first voiceprint corresponding to the employee and a second voiceprint corresponding to the caller. The computing platform may compare the second voiceprint to a known voiceprint corresponding to the client. Based on the comparison of the second voiceprint to the known voiceprint, the computing platform may determine that the second voiceprint does not match the known voiceprint. The computing platform may identify that the second voiceprint corresponds to another employee of the enterprise, and may send a security notification indicating potential unauthorized account access to an enterprise computing device.Type: GrantFiled: November 23, 2020Date of Patent: December 6, 2022Assignee: Bank of America CorporationInventors: Charlene L.

Patent number: 11468750Abstract: Methods and systems of authoring audio signal(s) into haptic data file(s) are disclosed. An audio analysis module analyses the audio signal(s) using filterbank(s) or by performing a spectrogram analysis. Transients are detected in the audio signal. If present, the transients are processed to determine a transient score and a transient binary. A database stores device specific information and actuator specific information. A haptic perceptual bandwidth of an electronic computing device having an embedded actuator is determined by using information from the database. A user interface allows modification of time-amplitude values and transient values based on the determined haptic perceptual bandwidth. Authored time amplitude values are aggregated in authored audio descriptor data, which is passed to a transformation module that fits the data into the haptic perceptual bandwidth and implements algorithms to produce transformed audio descriptor data.Type: GrantFiled: October 13, 2020Date of Patent: October 11, 2022Assignee: Lofelt GmbHInventors: Maximilian Weber, James Mazur, Gwydion ap Dafydd, Daniel Büttner

Patent number: 11468893Abstract: Methods, systems, and apparatus for an automated calling system are disclosed. Some implementations are directed to using a bot to initiate telephone calls and conduct telephone conversations with a user. The bot may be interrupted while providing synthesized speech during the telephone call. The interruption can be classified into one of multiple disparate interruption types, and the bot can react to the interruption based on the interruption type. Some implementations are directed to determining that a first user is placed on hold by a second user during a telephone conversation, and maintaining the telephone call in an active state in response to determining the first user hung up the telephone call. The first user can be notified when the second user rejoins the call, and a bot associated with the first user can notify the first user that the second user has rejoined the telephone call.Type: GrantFiled: May 5, 2020Date of Patent: October 11, 2022Assignee: GOOGLE LLCInventors: Asaf Aharoni, Eyal Segalis, Yaniv Leviathan

Patent number: 11445065Abstract: A call screening computing system is described that is configured to perform voice captcha and real-time monitoring of calls into a contact center of an organization. The call screening computing system includes a chat bot configured to operate as an AI-based call screener. The chat bot is configured to perform voice captcha by sending a random question to a user device placing a call into the contact center, and analyzing the received answer to determine whether a user of the user device is human or a robot. The chat bot is configured to, based on the user being human, determine whether the user is a legitimate customer of the organization by generating and presenting authentication challenges to the user device. The chat bot may be configured to monitor and interact with a conversation between the user and an agent of the organization during the call into the contact center.Type: GrantFiled: September 28, 2020Date of Patent: September 13, 2022Assignee: Wells Fargo Bank, N.A.Inventors: Julio Jiron, Kevin King, Beth S.

Patent number: 11438456Abstract: Introduced here is a platform for actively managing communication channels. In particular, the communication channels are managed to increase the probability of success of a call center agent to meaningfully engage with a client. In addition, the platform provides identification information and other information to facilitate a conversation between the parties, while also reducing the pre-call preparation by an agent. The platform parses search results to identify contact information for prospect by utilizing keyword identification algorithm. During the call, the platform applies voice detection and speaker detection algorithms to ensure that the agent is speaking with a live voice, rather than a pre-recorded message. By applying these algorithms, the platform aims to increase call center efficiency and conversation rates, while reducing pre-call preparation and skepticism of a prospect.Type: GrantFiled: October 2, 2020Date of Patent: September 6, 2022Inventor: Derek Allan Boman

Patent number: 11425257Abstract: [Problem] Provided is a relaying device that can track and record a communicated voice of a specific communication terminal using a mixing function of the relaying device. [Solution] When a communication terminal has sent a call packet to call another at least one communication terminal, a communication session in which this communication terminal that has made a call and a communication terminal that has been called are participating terminals is established. In the communication session, voice communication is relayed by transferring a voice signal which is transmitted from the participating terminals to another at least one communication terminal. A virtual device is registered as a participating terminal of the communication session and the voice signal which is transmitted from the communication session to the virtual device is recorded in the relaying device.Type: GrantFiled: April 26, 2019Date of Patent: August 23, 2022Assignee: ICOM INCORPORATEDInventor: Hisaaki Matsushima
