  • at an electronic device with a processor and memory storing one or more programs for execution by the processor;

    receiving, from a network interface, a first speech input;

    processing the first speech input using a first automatic speech recognition system to produce a first speech recognition result;

    performing a first task corresponding to a first user intent determined from the first speech recognition result;

    upon performing the first task, receiving, from the network interface, an input representing a rejection of the first task;

    in response to receiving the input, providing a prompt seeking a repetition of at least a portion of the first speech input;

    receiving, from the network interface, a second speech input;

    in accordance with the received input representing a rejection of the first task, processing the second speech input using a second automatic speech recognition system to produce a second speech recognition result, wherein the first automatic speech recognition system includes one or more speech recognition models, and the second automatic speech recognition system includes one or more speech recognition models that are different from the one or more speech recognition models of the first automatic speech recognition system;

    determining a combined speech recognition result based on the first speech recognition result and the second speech recognition result; and

    performing a second task corresponding to a second user intent determined from the combined speech recognition result.
