A method at a first electronic device of a local group of connected electronic devices includes: receiving a first voice command including a request for a first operation; determining a first target device for the first operation from among the local group; establishing a focus session with respect to the first target device; causing the first operation to be performed by the first target device; receiving a second voice command including a request for a second operation; determining that the second voice command does not include an explicit designation of a second target device; determining that the second operation can be performed by the first target device; determining whether the second voice command satisfies one or more focus session maintenance criteria; and if the second voice command satisfies the focus session maintenance criteria, causing the second operation to be performed by the first target device.
