Claim 6:
7. The network microphone device of claim 3, wherein the wake phrase is a first wake phrase, wherein the program instructions that are executable by the one or more processors further comprise program instructions that are executable by the one or more processors such that the network microphone device is configured to concurrently activate the first wake phrase engine associated with the voice service and the second wake phrase engine associated with another voice service, wherein the activated first wake phrase engine is configured to perform a wake phrase detection process for determining whether the captured audio content includes the first wake phrase, wherein the activated second wake phrase engine is configured to perform a wake phrase detection process for determining whether the captured audio content includes a second wake phrase, and wherein the program instructions stored on the at least one tangible, non-transitory computer-readable medium that are executable by the one or more processors such that the network microphone device is configured to use the second algorithm to confirm whether the first algorithm detected the wake phrase in the captured audio content comprise further program instructions that are executable by the one or more processors such that the network microphone device is configured to:
confirm that (i) the captured audio content includes the first wake phrase via the first wake phrase engine and (ii) the captured audio content does not include the second wake phrase via the second wake phrase engine.
