GNU Wget (or just Wget, formerly Geturl, also written as its package name, wget) is a
computer program that retrieves content from web servers. It is part of the GNU Project.
Its name derives from World Wide Web. It supports downloading via HTTP, HTTPS, and
FTP.( https://en.wikipedia.org/wiki/Wget)
NOTE: The -O in the command above is the letter O ,not0( the number ), meaning the

and written to file.

sudo tar -xzvf sphinxbase.tar.gz
sudo tar -xzvf pocketsphinx.tar.gz

Then install bison, ALSA, and swig:
sudo apt-get install bison libasound2-dev swig
sudo apt-get install python3 python3-dev python3-pip build-essential libpulse-dev
Bison is a program that converts the formal description of a computer language grammar
into a C language program that can parse the syntax and symbols of that grammar into
instructions that the computer can execute.
ALSA, also known as Advanced Linux Sound Architecture, is a software framework and
part of the Linux kernel that provides an application programming interface (API) for sound
card device drivers.
Swig, the Simplified Wrapper and Interface Generator, is an open-source software tool
used to connect computer programs or libraries written in C or C++ with other scripting
languages, in our case, Python.
