+# __Mini project Third Year__
+
+## __Voice Assistant(Backend)__
+
+Python Mudules required:
+
+    pyttsx3 module
+    wikipedia
+    speech_recognition module
+
+You may get error in windows regarding [pyaudio](https://pypi.org/project/PyAudio/) , to solve that error you have two options:
+
+__Option 1__
+
+* Go to [pyaudio unofficial binaries](https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyaudio) and download any of the previous versions.
+
+* For more information refer the [details](http://people.csail.mit.edu/hubert/pyaudio/).
+
+* Open the powershell window in the diretory where you have downloaded it.
+
+* Then use `pip` to install the pyaudio file.
+
+example:
+>pip install .\PyAudio‑0.2.11‑cp310‑cp310‑win_amd64.whl
+
+
+
+__Option 2__ 
+
+* Go to terminal and enter:
+
+>pip install pipwin
+
+>pipwin install pyaudio
+
+* For more information about `pipwin` refer the [documentation](https://pypi.org/project/pipwin/)
