Speech-enabled web content searching using a multimodal browser implemented with one or more grammars in an automatic speech recognition (‘ASR’) engine, with the multimodal browser operating on a multimodal device supporting multiple modes of interaction including a voice mode and one or more non-voice modes, the multimodal browser operatively coupled to the ASR engine, includes: rendering, by the multimodal browser, web content; searching, by the multimodal browser, the web content for a search phrase, including yielding a matched search result, the search phrase specified by a first voice utterance received from a user and a search grammar; and performing, by the multimodal browser, an action in dependence upon the matched search result, the action specified by a second voice utterance received from the user and an action grammar.
