How to create custom recipes for p4a in Python?

Question

So I am trying to use the SpeechRecognition package with my Kivy app. I am using buildozer to build and deploy, but I need to create a custom recipe for the SpeechRecognition package.

So far I have downloaded the p4a folder with all the recipes and created a new folder 'speech_recognition'. When building the app buildozer tries to download the package but then fails. I guess I need help with how to exactly setup my recipe file.

I have looked at a bunch of example recipes available here.

Here is my speech_recognition/__init__.py

from pythonforandroid.recipe import CppCompiledComponentsPythonRecipe
class SRRecipe(CppCompiledComponentsPythonRecipe):
    version = '3.8.1'
    url = 'https://github.com/Uberi/speech_recognition/archive/{version}.zip'
    site_packages_name = 'speech_recognition'
    #depends = ['setuptools']
recipe = SRRecipe()

Here is the console output:

[INFO]:    -> running mkdir -p /home/lukas/Documents...(and 86 more)

What is strange to me is that the url in the output is not the same as the url i specify? Any help would be appreciated.
