The data is provided to a server system. A textual query that has been determined by a speech recognizer at the server system to be a textual form of at least part of the data is received at the mobile computing device. The textual query is determined to include a carrier phrase of one or more words that is reserved by a first third-party application program installed on the computing device. The first third-party application is selected, from a group of one or more third-party applications, to receive all or a part of the textual query. All or a part of the textual query is provided to the selected first application program. ## Claims ### Claim 1 A computer-implemented method that when executed on data processing hardware of a computing device causes the data processing hardware to perform operations comprising: receiving a voice input captured by the computing device, the voice input comprising a beginning portion that includes a particular phrase and a remaining portion that includes a particular voice command;
