    摘要: A method for determining potentially undesirable voices, in embodiments, includes: receiving audio recordings comprising voices associated with undesirable activity, and determining audio components of each of the audio recordings. The method may further comprise generating a multi-dimensional vector of the audio components for each of the plurality of audio recordings, and comparing audio components between the multi-dimensional vectors to determine clusters of multi-dimensional vectors, each cluster comprising two or more of the multi-dimensional vectors of audio components, wherein each cluster corresponds to a blacklisted voice. The method may further comprise receiving an audio recording or audio stream, and determining whether the audio recording or audio stream is associated with a voice associated with undesirable activity based on a comparison to the clusters.

    摘要: Video conferencing in a controlled environment facility entails significant security concerns. These concerns are even more prevalent in a system that permits residents of such facilities to communicate via their own personal devices. Therefore, in order to alleviate these concerns and provide a secure system in which a resident is able to make video calls using their personal device, a kiosk unit is provided to which the personal device must be linked for completing a video call. When making the video call, the camera and display on the personal device are disabled, and all video data is captured and displayed by the kiosk unit. The link between the kiosk unit and the personal device facilitates the exchange of the image information for transmission to the outside party, or display to the user. By providing a fixed camera, and disabling the personal device camera, security can be maintained while permitting video calling services.

    摘要: A system and method for multilingual authentication access to a communication system in a controlled environment is disclosed. The system includes a communication subsystem that connects a communication between a first communication device and a second communication device, wherein one of the first communication device or the second communication device is used by the inmate of the correctional system. The system also includes a profile subsystem configured to determine profile information of a party associated with the first communication device. The system further includes an authentication subsystem that provides one or more challenge questions to the first communication device based on the profile information, receives at least one response to the one or more challenge questions from the first communication device, and authorizes connection of the communication between the first communication device and the second communication device based on the at least one response.

    摘要: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for a dynamic threshold for speaker verification are disclosed. In one aspect, a method includes the actions of receiving, for each of multiple utterances of a hotword, a data set including at least a speaker verification confidence score, and environmental context data. The actions further include selecting from among the data sets, a subset of the data sets that are associated with a particular environmental context. The actions further include selecting a particular data set from among the subset of data sets based on one or more selection criteria. The actions further include selecting, as a speaker verification threshold for the particular environmental context, the speaker verification confidence score. The actions further include providing the speaker verification threshold for use in performing speaker verification of utterances that are associated with the particular environmental context.
