Abstract: Systems and methods are provided for optimizing and securing an enterprise voice service accessed by an external voice assistant device. An enterprise voice assistant installed on a client device acts as an enterprise voice service for an external voice assistant device. The enterprise voice assistant receives a voice query from the external voice assistant device. The voice query is processed using a machine learning model to extract an intent and at least one slot. The extracted intent and at least one slot are used to determine whether a response to the voice query can be generated using local enterprise data that was previously received and stored by the client device from a management server. The response is generated based on the determination by using the local enterprise data or by sending the extracted intent and at least one slot to and receiving the response from the management server.
