Techniques for implementing multiple wakeword detectors on a single device are described. A digital signal processor (DSP) of the device may implement a wakeword detection component to detect when captured speech includes a wakeword. A companion application installed on the device may implement a wakeword detection component trained using speech of a user of the device. In response to determining that the user spoke the wakeword, the companion application may send audio data representing the speech and data corresponding to the user to at least one server(s) for processing. Further, the device may receive captured speech and captured image data corresponding to the captured speech and determine a representation of a user in the captured image data. If the device determines the user is represented in the image data, audio data representing the speech may be sent to at least one server(s) for processing.
