16. A method to invoke actions for sequence dependent operations in a voice activated data packet based computer network environment, comprising: receiving, by a natural language processor component executed by a data processing system data packets comprising an input audio signal detected by a sensor of a client computing device; identifying, by the natural language processor component, based on the input audio signal, a request and a trigger keyword corresponding to the request; determining, by a prediction component, a thread based on the trigger keyword and the request, the thread comprising a first action, a second action subsequent to the first action, and a third action subsequent to the second action; providing, by the prediction component, to a content selector component of the data processing system, an indication of the third action prior to occurrence of at least one of the first action and the second action; selecting, by the content selector component, based on the third action and the trigger keyword identified by the natural language processor, a content item via a real-time content selection process; obtaining, by an audio signal generator component executed by the data processing system, an output signal comprising the content item; and transmitting, via an interface of the data processing system, data packets comprising the output signal obtained by the audio signal generator component to cause an audio driver component executed by the client computing device to drive a speaker of at least one of the client computing device and a second client computing device to generate an acoustic wave corresponding to the output signal prior to occurrence of at least one of the first action and the second action.
16. A method to invoke actions for sequence dependent operations in a voice activated data packet based computer network environment, comprising: receiving, by a natural language processor component executed by a data processing system data packets comprising an input audio signal detected by a sensor of a client computing device; identifying, by the natural language processor component, based on the input audio signal, a request and a trigger keyword corresponding to the request; determining, by a prediction component, a thread based on the trigger keyword and the request, the thread comprising a first action, a second action subsequent to the first action, and a third action subsequent to the second action; providing, by the prediction component, to a content selector component of the data processing system, an indication of the third action prior to occurrence of at least one of the first action and the second action; selecting, by the content selector component, based on the third action and the trigger keyword identified by the natural language processor, a content item via a real-time content selection process; obtaining, by an audio signal generator component executed by the data processing system, an output signal comprising the content item; and transmitting, via an interface of the data processing system, data packets comprising the output signal obtained by the audio signal generator component to cause an audio driver component executed by the client computing device to drive a speaker of at least one of the client computing device and a second client computing device to generate an acoustic wave corresponding to the output signal prior to occurrence of at least one of the first action and the second action. 18. The method of claim 16 , comprising: receiving, by the natural language processor component from the client computing device, a packet based data message to cancel the third action within a time interval triggered by one of the first action and the second action.
