A computer system can include a hotword manager, a hotword detection module, and a browsing application. The hotword manager can maintain information for a plurality of hotwords that correlates identifiers for the hotwords with respective representations for the hotwords. The hotword detection module can listen for spoken input and detect when spoken input corresponds to one of the plurality of hotwords. The browsing application can (i) parse an electronic document to identify respective identifiers for one or more hotwords included in the electronic document, (ii) generate a display of the electronic document that includes respective representations for the one or more hotwords, the respective representations obtained from the hotword manager using the identifiers for the one or more hotwords included in the electronic document, and (iii) perform a particular set of operations in response to identifying spoken input for a particular hotword included in the electronic document.
