Abstract:
A system including a conferencing telephone coupled to or in communication with an identification service (111). The identification service (111) is configured to poll user devices of conference participants to determine or confirm identities. In response, the user devices transmit audio electronic business cards, which can include user voice samples and/or preprocessed voice recognition data. The identification service (111) stores the resulting audio electronic business card data. When the corresponding participant speaks during the conference, the identification service (111) identifies the speaker.
Abstract:
Embodiments of the present invention are directed generally to use of biometric identification during a call for detecting an anomaly occurring in the call, such as a change in the parties (11, 13) participating on the call Communication between parties of a call (11, 13) is monitored and biometric identification is performed using the communication In one embodiment, Biometric prints (105), such as voice prints (105A), face prints, etc, are obtained for parties (11, 13) authorized to participate on a call The call is monitored and biometric data (105) captured from communication during the call is compared with the biometric prints of the authorized parties (11, 13) to detect changes in the parties participating on the call, such as a new, unauthorized party joining the call. Thus, a call processing system (10) can detect anomalies occurring during monitored calls such as three-way calling, a handoff of a call etc.
Abstract:
Verfahren zur Steuerung eines Nutzerzugriffs auf einen in einem Datennetz bereitgestellten Dienst, um in einer Datenbasis des Dienstes gespeicherte Nutzerdaten gegen unberechtigten Zugriff zu schützen, wobei das Verfahren aufweist: Eingeben einer Sprachprobe des Nutzers in einer VoIP-Session an einem Nutzer-Datenendgerät, welches mindestens zeitweilig mit dem Datennetz verbunden ist, Verarbeiten der Sprachprobe des Nutzers in einem ersten Verarbeitungsschritt, unter Nutzung eines dedizierten Client, der im Nutzer-Datenendgerät implementiert ist, um eine vorverarbeitete Sprachprobe oder ein aktuelles Stimmprofil des Nutzers zu erhalten, weiteres Verarbeiten der vorverarbeiteten Sprachprobe oder des a ktuellen Stimmprofils in einem zweiten Verarbeitungsschritt, einschließend einen Vergleichsschritt des aktuellen Stimmprofils mit einem in einer Datenbasis gespeicherten initialen Stimmprofil, und Ausgeben eines Zugriffssteuersignals zur Gewährung oder Verweigerung eines Zugriffs auf den Dienst unter Berücksichtigung des Ergebnisses des Vergleichsschrittes.
Abstract:
One-to-many comparisons of callers' words and/or voice prints with known words and/or voice prints to identify any substantial matches between them. When a customer communicates with a particular entity, such as a customer service center, the system makes a recording of the real-time call including both the customer's and agent's voices. The system segments the recording to extract different words, such as words of anger. The system may also segment at least a portion of the customer's voice to create a tone profile, and it formats the segmented words and tone profiles for network transmission to a server. The server compares the customer's words and/or tone profiles with multiple known words and/or tone profiles stored on a database to determine any substantial matches. The identification of any matches may be used for a variety of purposes, such as providing representative feedback or customer follow-up.
Abstract:
A method and system for secure authentication of a user in a session conducted over an interactive communication channel, such as a two-way telephony communication channel, with an authenticating entity, such as a financial institution, utilizes a session identifier, such as pseudorandom noise to detect and identify attempts to play back authentication information, such as user-spoken phrases, intercepted and recorded by an unauthorized party during a previous session between the user and the authenticating party.
Abstract:
状態判定部14により発話区間と判定すると、音源位置検出部15により各音源9 1 ~9 K の位置を検出し、それらの音源に対応して共分散行列算出部17により受音信号の共分散行列を求め、各音源に対応して共分散行列記憶部18に保存する。共分散行列から各音源の収音レベルを収音レベル推定部19により推定し、出力レベルが所定値となるよう、フィルタ係数算出部21により推定収音レベルと共分散行列からフィルタ係数を決定し、フィルタ12 1 ~12 M に設定する。これらフィルタによりそれぞれのマイクロホンからの受音信号を処理し、処理結果を加算器13で加算して送話信号として出力することにより、音源の位置にかかわらず、それぞれ所望のレベルの送話信号を生成できる。
Abstract:
A communication terminal which displays individual information of a source person at a communication start upon a signal reception. The communication terminal includes a FLASH-ROM (10) as a database for storing individual information of registered individuals correlated with individual voiceprint information, a voiceprint analysis unit (6) for extracting voiceprint information of a source person from the voice of the source person at communication start upon a signal reception, an MPU (7) for comparing the voiceprint information of the source person with the voiceprint information in the database so as to identify the source person among the individuals in the database, and an LCD (17) as a display unit for displaying the individual information of the specified source person.
Abstract:
A computer system may communicate metadata that identifies a current speaker. The computer system may receive audio data that represents speech of the current speaker, generate an audio fingerprint of the current speaker based on the audio data, and perform automated speaker recognition by comparing the audio fingerprint of the current speaker against stored audio fingerprints contained in a speaker fingerprint repository. The computer system may communicate data indicating that the current speaker is unrecognized to a client device of an observer and receive tagging information that identifies the current speaker from the client device of the observer. The computer system may store the audio fingerprint of the current speaker and metadata that identifies the current speaker in the speaker fingerprint repository and communicate the metadata that identifies the current speaker to at least one of the client device of the observer or a client device of a different observer.
