Abstract: In some implementations, a voice analysis system may receive, from a telecommunications system, an audio stream associated with a user. The voice analysis system may provide the audio stream to a machine learning model in order to receive a plurality of indicators associated with the audio stream. The plurality of indicators may be associated with a pitch of the user, a tone of the user, a speaking rate of the user, an emotional state of the user, or a vocabulary of the user. The voice analysis system may estimate whether the audio stream is associated with fraud based on the plurality of indicators. The voice analysis system may transmit, to an administrator device, an indication of whether the audio stream is associated with fraud.

Abstract: An example computing system may be configured to cause one or more playback devices located in a location of a commercial environment to play back an advertisement. The example computing system may also be configured to receive an indication that a user device is detected proximate to the location, during playback of the advertisement. The example computing system may also be configured to, after receiving the indication that the user device has been detected, receive an indication of a purchase of the subject of the advertisement, the purchase associated with the user profile. The example computing system may also be configured to, based on (i) the indication that the user device has been detected during play back of the advertisement and (ii) the indication of the purchase of the subject of the advertisement, cause a content service account associated with the computing system to be updated.

Abstract: Example techniques may involve a playback device modifying its playback configuration when the playback device is placed onto a device base. In an example implementation, the playback device may receive, via an 802.15-compatible radio of one or more network interfaces, one or more packets comprising data representing an identifier of the first device base. After receipt of the one or more packets, the playback device queries a database for state information corresponding to the identifier of the first device base and modifies a playback configuration of the playback device from a first configuration to a second configuration based on the queried state information corresponding to the identifier of the first device base.

Abstract: Examples described herein involve networking in a media playback system. In one aspect, an access point may prevent two or more grouped playback devices from being steered to different networks. In another aspect, an access point may operate as a sleep proxy for a playback device. In a third aspect, an example system may include a fixture configured to receive a bulb. Example bulbs include sound bulbs with one or more audio transducers and access point bulbs, among other examples.

Abstract: Systems and methods for authenticating a passive speaker include (i) activating, by a playback device configured to drive the passive speaker, a passive speaker identification circuit of the passive speaker by providing an identification signal to an input terminal of the passive speaker, wherein the passive speaker is a particular type of passive speaker having particular acoustic characteristics; (ii) while the passive speaker identification circuit is active, measuring, by the playback device, an electrical current of the identification signal; (iii) determining, based on the measured electrical current of the identification signal, an impedance modulation of the passive speaker; (iv) determining, by the playback device, the particular type of the passive speaker based on the impedance modulation of the passive speaker; and (v) applying, by the playback device, a calibration to the playback device based on the determined particular type of the passive speaker.

Abstract: A method, a system, and a computer program product for executing transactions using contactless cards. A near-field communication (NFC) exchange is executed between a first device and a second device upon the first device being detected by the second device to be located within a predetermined distance of the second device. The first device is associated with an electronic deposit account capable of receiving an electronic transfer of funds. At least one identification data associated with the first device is received from the first device based on the NFC exchange and sent to a server. A response from the server is processed and includes an authentication data corresponding to the first device and associated with the sent identification data. A request for electronically transferring predetermined electronic funds to the electronic deposit account is received.
