A system to control digital components in a voice-activated system, comprising: a data processing system comprising one or more processors and a memory, the one or more processors executing a natural language processor component, an annotation component, a digital component selector and a parsing component to: receive, by the natural language processor component and via interface of the data processing system, a first input audio signal detected by a sensor at a client computing device; parse, by the natural language processor component, the first input audio signal to identify a digital component request in the first input audio signal, the digital component request indicating a first digital component, wherein the first digital component comprises audio and/or visual content; select, by the digital component selector, the first digital component in response to the digital component request identified in the first input audio signal; generate, by the annotation component, a first set of annotations of the first digital component based at least on speech recognized in the first digital component; identify, by the parsing component, a plurality of break points based on at least the first set of annotations to define a plurality of portions within the audio and/or visual content of the first digital component, wherein each of the portions is defined between two break points (202, 202) in the audio and/or visual content of the first digital component; receive, by the natural language processor component, a second input audio signal detected by the sensor at the client computing device; parse, by the natural language processor component, the second input audio signal to identify a term in the second input audio signal; select, by the parsing component, a break point (202) from the plurality of break points based on the term in the second input audio signal and the first set of annotations used to identify the break point; and transmit, by the parsing component to the client computing device, a portion of the first digital component corresponding to the selected break point, wherein the selected break point corresponds to the start of the portion of the first digital component. receive, by the natural language processor component and via interface of the data processing system, a first input audio signal detected by a sensor at a client computing device; parse, by the natural language processor component, the first input audio signal to identify a digital component request in the first input audio signal, the digital component request indicating a first digital component, wherein the first digital component comprises audio and/or visual content; select, by the digital component selector, the first digital component in response to the digital component request identified in the first input audio signal; generate, by the annotation component, a first set of annotations of the first digital component based at least on speech recognized in the first digital component; identify, by the parsing component, a plurality of break points based on at least the first set of annotations to define a plurality of portions within the audio and/or visual content of the first digital component, wherein each of the portions is defined between two break points (202, 202) in the audio and/or visual content of the first digital component; receive, by the natural language processor component, a second input audio signal detected by the sensor at the client computing device; parse, by the natural language processor component, the second input audio signal to identify a term in the second input audio signal; select, by the parsing component, a break point (202) from the plurality of break points based on the term in the second input audio signal and the first set of annotations used to identify the break point; and transmit, by the parsing component to the client computing device, a portion of the first digital component corresponding to the selected break point, wherein the selected break point corresponds to the start of the portion of the first digital component.
