Compare a fragment of an audio file to a long audio file

Question

I would like to develop a program (preferably in python, however, java or c++ would be ok too) that compares an audiofile (length around 1 to 2 seconds) to a database of audiofiles of longer duration (10 to 60 minutes). It should find the long audiofile which the small audiofile is an (almost) exact subsequence of. I know there exist some tools for that, however most require the short sequence to be a bit longer and specialize in matching a noisy sequence of music. I have also not found any libraries that seems particularly helpful. I would like to focus on speech though. Are there tools for this (I can interact programatically with)? Are there python libraries to this purpose, or how would I go about implementing something like that on my own? Thank you
