Python speech recognition is not working using SpeechRecognition 3.8.1 library

In my Python 3.8.6 project, I have installed "pip install SpeechRecognition" for my windows 10 computer. And the code sample is below,
import speech_recognition as sr
listener = sr.Recognizer()
try:
with sr.Microphone() as source:
print('Listening...')
voice = listener.listen(source)
command = listener.recognize_google(voice)
print(command)
except:
print("Something else went wrong")
pass
After run this code, output is below,
Something else went wrong
I have already microphone build-in with my laptop and also I have checked it also using plug an external USB microphone. Then what is the problem in here? Is there need any hardware configuration to solve this issue?

In the Speech Recognition Readme on PyPI, you can see there is a PyAudio Section. It means you have to have PyAudio Installed on your machine. But if you have PyAudio intsalled and you get an error, you need to share the error without the try except blocks, so we can analyze the error and give a solution.
To install PyAudio, execute pip install pyaudio in the terminal.
Sometimes pip install pyaudio can throw an error similar to this:

Steps to fix this error:
Go to your terminal and execute python --version and in the case of Optimus Prime, his version is Python 3.8.6
Find if your Python Installation is 64 bit or 32 bit which you can see by going to your Python Terminal
Download a PyAudio Wheel file based on your Python version and your Python installation (64 bit / 32 bit)
Open up a Terminal in the directory where you have downloaded the Wheel File (.whl)
Then execute pip install <name of your wheel file>
And you are done!

Thank you,

Nope you can't use sudo because you don't get root access for colab.
The problem is that you don't just need libasound2-dev but a whole host of packages. Check debian requirements in https://textract.readthedocs.io/en/stable/installation.html
Also in order to build sphinx (a requirement for textract) you need libpulse-dev. So here is the updated command list.
!apt-get install python-dev libxml2-dev libxslt1-dev antiword unrtf poppler-utils \
pstotext tesseract-ocr \
flac ffmpeg lame libmad0 libsox-fmt-mp3 sox libjpeg-dev swig libasound2-dev libpulse-dev
!pip install git+https://github.com/deanmalmgren/textract

In google colab Bash commands run by prefixing the command with ‘!’.
Example:
!apt update
!apt-get install libasound2-dev

To fix the problem, I downloaded swig for windows at the time of writing this answer it was 3.0.12
For the latest swig windows version follow this link
Copy swig.exe to the python installation folder (for ex C:/python27)
Open the swigwin-3.0.12/Lib folder and copy all *.swg files to the C:/python27/Lib or equivalent python path
Open swigwin-3.0.12/Lib/python and copy all the files to C:/python27/Lib
Open the swigwin-3.0.12/Lib folder and copy over the typemaps folder to C:/python27/Lib
(Also make sure you have Microsoft Visual C++ Compiler for Python installed)
These steps worked for me.

conda install swig
pip install pocketsphinx
I didn't want to do all that setup other people are suggesting so I tried this and it worked.
This probably only works if you are using Anaconada though.

Instead of copying Swig files to the Python folder, you can simply add Swig`s location to the environment variables:
Press Ctrl+S
Type env and press Enter
Double click on Path
Add the path-to-Swig to the last blank line
Click OK and restart your PC

You try to install pocketsphinx with pip, that will download and compile this module. It requires some compiling tool like swig.
Another solution is to install a binary version of pocketsphinx. You can download a binary version here. You have to select the correct version with respect to your installation.
To determine which one you have to download, you can run the following commands, that will tell you which version you require and whether you run a 32 or 64 bit python interpreter.
"C:\Users\krush\Anaconda3\python.exe" --version
"C:\Users\krush\Anaconda3\python.exe" -c "import struct;print(struct.calcsize('P') * 8)"
Below are some commands that you may enter once you have downloaded the correct version
"C:\Users\krush\Anaconda3\python.exe" -m pip install pocketsphinx‑0.1.3‑cp35‑cp35m‑win32.whl
"C:\Users\krush\Anaconda3\python.exe" -m pip install pocketsphinx‑0.1.3‑cp36‑cp36m‑win_amd64.whl

I was also getting same error, while installing in ubuntu 16.04, I executed following commands:
sudo apt-get install -y python python-dev python-pip build-essential swig git libpulse-dev
sudo pip install pocketsphinx
source: pocketsphinx-python

In case you are working on anaconda navigator.
Just go to environment.
Search swig, your package will be displayed. Select the package and click on apply button.
It will also give a prompt list of other dependencies, which need to be installed with swig.
So just select all and click on apply button.
All the dependencies will be installed in your root directory of anaconda.
This worked for me, hope it helps.

There are few set of commands to resolve this. Just execute them:
sudo apt-get install -y python3 python3-dev python3-pip build-essential swig git libpulse-dev
sudo apt-get install libasound2-dev
sudo pip install pocketsphinx

what works for me is installing swing from conda and
conda install swig
if installed search where it is installed
where swig
then add that path to your environment variable

For mac users getting similar issues, there seems to be a problem with the current pip install framework. I followed this thread and used the solution linked. It doesn't seem like there will be a pip fix anytime soon.
Note you'll have to brew install swig before running the above steps - homebrew install link.

pip install pipwin
python -m pipwin install pocketsphinx
You can also use pipwin to install pocketsphinx.

For a purely pip-based fix (may or not work depending on your exact issue/system):
pip install swig
pip install pocketsphinx
pip freeze > requirements.txt
Fixed the issue simply for me. With pip freeze, you're likely to not have the issue again if cloning the project in another system (since swig will be installed just with pip install -r requirements.txt)
This is the kind of things for which it becomes REALLY worthwhile to look into using virtualenv or similar, instead of polluting (and endlessly re-configuring) your system.

I know I am late, but what worked for me was to download the pre-built wheel file and install it manually (tested on Windows. I am pretty sure it will only work on Windows).
https://www.lfd.uci.edu/~gohlke/pythonlibs/#pocketsphinx
Just grab the right one (cp39 = python 3.9). When it finishes downloading, navigate to your downloads folder in cmd, and issue the following command:
pip install pocketsphinx-0.1.15-cp39-cp39-win_amd64.whl
NOTE: Change pocketsphinx-0.1.15-cp39-cp39-win_amd64.whl to the name of the whl file you downloaded. I grabbed this one because I use Python 3.9 64bit version.

Error when installing cmake for python windows

I have windows 10 and fresh Python 3.6.1.
I was trying to install package Cmake 0.6.0 (needed for another package, atari-py) using
pip install cmake
but I'm getting an error.
I have these packages installed: pip,scikit-build, setuptools, wheel, pybdist.
I do have a foreign symbol in my account name (lesson learnt), but it works fine when installing other packages. I am not a skilled windows administrator.

python -m pip install --upgrade pip
and then you can run
pip3 install cmake
This works for me on Pyhton 3.8

if the above answers of pip3 or pip install cmake don't work try
sudo apt-get install cmake

As of today, CMake wheels for python 3.6 are available and pip install cmake is expected to work.
Background
At the time of your first post, there were no wheels for python 3.6, pip was rightfully trying to build the wheel using the source distribution.
Considering that:
the project allowing to generate a CMake wheel itself depends on scikit-build and cmake
we simply repackage the existing binaries into the windows wheels
... you got the general error message Problem with the CMake installation, aborting build.
References:
http://cmake-python-distributions.readthedocs.io
http://scikit-build.readthedocs.io/
Installing atari-py on windows
Looking at the documentation and open pull requests of the corresponding project, it look like windows is not supported. See https://github.com/openai/atari-py
If you would like to help the project and improve their windows support, let me know and I could try to give you some guidance to create a pull request and simplify their build system.

Eventually I installed cmake 0.8 from a binary file from their webpage.
I originally wanted to install package atari-py that needed cmake. I downloaded that from git and in cmd with administrator rights I ran
python install setup.py
which worked.
python setup.py install
still didn't work. Unfortunately I can't give any further explanation.

I just downloaded VS Code with C++ libraries and that did the trick, I was able to install CMake. (I was on Windows 10 btw)

I'm assuming that you have are on x64 bit Windows.
The cleanes way to solve it:
If you have installed 32 bit version of python: uninstall it
install 64 bit
During setup choose to add python to path
Download 64 bit version of pillow:
http://wp.stolaf.edu/it/installing-pil-pillow-cimage-on-windows-and-mac/
Run the setup file.

Check your Pip version to see if you have the last version available.
C:\ python3 -m pip install --version
You can either use python or python3, I used python3 because I have 2.7 and 3.5 on the same disk.
If your version is not the latest update with:
C:\ python3 -m pip install --upgrade pip
Then now try pip install Pillow again:
C:\ python3 -m pip install Pillow
This time it has to work without problems.

You're getting this error because the pillow version you're trying to install is incompatible with your python version.
Try upgrading both as a final resort.
