Claim 15:
16. The computing system of claim 7, wherein the program instructions that, when executed by the one or more processors, further cause the one or more processors to at least:
subsequent to causing the embedding vector to be generated, receive an indication of a first keyword that if detected as spoken is to cause an action to be performed;
subsequent to receiving the indication of the first keyword, receive a first audio data segment;
convert the first audio data segment into a first log melspectrogram;
process the first log melspectrogram to determine a first probability score indicative of a first probability that the first audio data segment includes the first keyword;
determine that the first probability score exceeds a first confidence threshold corresponding to the first keyword; and
in response to a determination that the first probability score exceeds the first confidence threshold, cause the action to be performed.
