Claim 19:
20. The apparatus of claim 17,
wherein the program instructions that, when executed by the one or more processors, further cause the one or more processors to at least:
determine that a length of the second audio data segment is greater than a defined length; and
in response to a determination that the length of the second audio data segment is greater than the defined length, segment the second audio data segment into a third audio data segment of the defined length and a fourth audio data segment of the defined length; and

wherein the program instructions that, when executed by the one or more processors to convert the second audio data segment into the second log melspectrogram, further include instructions that, when executed by the one or more processors, further cause the one or more processors to at least:
convert the third audio data segment into a third log melspectrogram; and
convert the fourth audio data segment into a fourth log melspectrogram; and

wherein the program instructions that, when executed by the one or more processors to process the second log melspectrogram, further include instructions that, when executed by the one or more processors, further cause the one or more processors to at least:
process the third log melspectrogram and the fourth log melspectrogram to determine that at least a portion of the third log melspectrogram or at least a portion of the fourth log melspectrogram represent the second keyword.
