Abstract: A voice-biometrics based solution for unwanted self-invocations by virtual assistant applications is proposed. In various embodiments, a processing system is configured to control a virtual assistant. The processing system may have stored in a memory at least one voiceprint created using voice biometrics based on recorded utterances of synthetic speech from the virtual assistant. The at least one voiceprint may be used to prevent self-invocation of a virtual speech session by matching the voiceprint created using the synthetic speech utterances with the incoming audio stream.
