Abstract: Methods and systems for processing audio information captured by an interactive virtual assistant (IVA). An example method includes: converting sound received by a microphone into electrical signals; generating voiceprints corresponding to voices represented in the electrical signals; distinguishing signals representing background speech and signals representing voice commands directed at the IVA; and based on various signals representing background speech and voice commands, labeling each of the voiceprints with a tag selected from the group consisting of an IVA interactor occupant tag, an IVA non-interactor occupant tag, and a non-occupant tag. The method also includes transmitting, in response to a trigger event, a message with at least one of an estimated number of occupants in a geofenced area corresponding to the IVA and an alert reporting an indication of unlawful activity thereat.

Abstract: A portable radio (100) provides a voice control feature which advantageously enables radio users to perform talk group changes by using voice as an input medium to the radio device. Activation of a voice control button (110) and verbal entry of a valid talk group control command enables a change in talk group. The portable radio (100) comprises a controller (102) having a code plug (120) pre-programmed with a plurality of talk group alias names, and an automatic speech recognition (ASR) engine (118) providing voice control entry detection to the portable radio. The controller (102) enables a change in talk group in response to the ASR engine (118) detecting that the voice control entry is a valid talk group control command. Shortened audible confirmations of talk group change are generated using the alias names.

Abstract: Improved user authentication of a communication device is provided by expanding voice biometric authentication with a dynamically updated user profile formed of non-voice usage parameters. The non-voice usage parameters are collected during successful voice authentications to establish non-voice compensation controls. When a failed voice biometric authentication attempt is followed by a valid PIN entry, then a false rejection is determined, and a voice biometric threshold is adjusted to reduce the individual user-based false rejection rate along with the enablement of the non-voice usage controls.
