You must use python versions 2.7, 3.4, 3.6 otherwise there will be an error.supporting python versions
I downloaded this version 'https://www.python.org/downloads/release/python-2717/' of python and it was able to install pyaudio.
pyaudio installed
If you have several versions of Python, then for example to run pip for Python 2.7.17 use this command:
py -2 -m pip install pyaudio
module pyaudio

Is there any way I can solve this installation issue or reach my goal using another API?

Basically it means that Python needs cl.exe and it expect it at:
C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Tools\MSVC\14.23.28105\bin\Hostx86\x64
No problem, I go to the Environment Variable and i add that path both for my user and for the system:
Then I check if cl.exe is successfully in the path by typing cl in the terminal and it works:
But when I run again pip install gmpy I have the same error.
EDIT: I also tried with pip install gmpy2 and I receive the same error.
Where am I wrong?

Well the actual problem is that you are missing some header file gmp.h:
C:\Users\franc\AppData\Local\Temp\pip-install-du1j9u7s\gmpy\src\gmpy.h(30): fatal error C1083: Cannot open include file: 'gmp.h': No such file or directory
I suggest you try gmpy2, which is a newer version. It has wheels for Windows on PyPI but they are for older versions of Python unfortunately. Pre-built wheels for more recent Python versions are available here. The files are named after the Python version (e.g. cp37 for CPython 3.7) and architecture (e.g. amd64 for 64-bit)
A wheel can be installed like so:
pip install gmpy2‑2.0.8‑cp37‑cp37m‑win_amd64.whl
