What kind of speech can this library recognize? (humans/birds/animals/etc?)

[adityakadrekar16]

Hello,

Is this library applicable only for human speech? I am trying out this library to see if it can detect bird speech. I passed a couple of bird wav files and it was able to detect speech in them. I thought something is amiss so I passed an instrumental music file and it detected speech in that which was strange. Can you please help me understand?

Thanks,
Aditya
