Python Text to Speech Example

Here you will get python text to speech example.

As we know, some people have difficulty reading large amounts of text due to dyslexia and other learning disabilities. Some people have basic literary levels. They often get frustrated trying to browse the internet because so much of it is in text form or on other hand some people prefer to listen or watch a news article (or something like this) instead of reading. So to solve all these problems a concept comes into mind that is ”text to speech”.

So in this tutorial we are going to learn that how to convert text to speech in Python. Here we’ll show you two best and easiest ways to convert your text into speech

  1. Text to speech without internet connection (using pyttsx3)
  2. Text to speech having internet connection (using gTTS)

Python Text to Speech Example

Method 1: Using pyttsx3

Pyttsx3 is an offline cross-platform Test-to-Speech library which is compatible with both Python 3 and Python 2 and supports multiple TTS engines

To use pyttsx3, first we have to download and install it. In order to install it open your command prompt or terminal and type this command.

pip install pyttsx3

If you’re using windows operating system then you also have to install “pypiwin32” to make it work. To install pypiwin32 again type this command and hit enter in command prompt.

python  -m  pip install pypiwin32

Make sure you’ve internet connection while running both of the command. It is one time process, after you’ve installed pyttsx3 now to use it, the program will be as shown below.

import pyttsx3
engine = pyttsx3.init()
engine.say("hello crazy programmer")
engine.setProperty('rate',120)
engine.setProperty('volume', 0.9)
engine.runAndWait()

In this program, in first Line we’re initializing pyttsx3 for use then we’re passing the text in method say(). After it we’re setting some properties like volume and rate of the voice. Here we’re passing 120 as rate, which means it will speak 120 words per minute and last line of above program will be produce an audio saying “hello crazy  programmer”.

We can also modify the voice like we can change it into female voice (by default its male), age and language. For more information please visit http://pyttsx3.readthedocs.io/en/latest/engine.html

Method 2: Using gTTS (Google Text to Speech)

Google Text to Speech is one of the best TTS API out there, because it will generate audio as approximately similar to human voice while other APIs generate audio like a metallic voice or robotic voice. But there is also a disadvantage of gTTS, it will need an internet connection to convert the text into an audio. So it can be slow then other offline APIs.

To install gTTS API open your command prompt or terminal and type this command:

pip  install gTTS

Program for conversion will be as shown below.

from gtts import gTTS
tts = gTTS(text="Hello crazy programmer", lang='en')
tts.save("audio.mp3")

Unlike other APIs it will generate an audio and will save into the same directory where your program stored.

To play this audio we’ll need another tool to play audio on command line.

If you’re using Linux (eg. Ubuntu) then mpg321 will be best command line player.

To install it open terminal and type this command-

sudo apt-get install mpg321

Now we can use this command to play any audio on command line:

mpg321 audio.mp3 -quiet

To run this command in python program, add these two lines into above program

import os     #will be on the top
os.system('mpg321 audio.mp3 -quiet')

On other hand, for windows, we doesn’t have to install any new software or API to play the mp3 file. All we have to do is open command prompt and enter the name of your file it will play that file using your default media player. So to run this command in python add these two lines in above program.

import os       #will be on the top
os.system("audio.mp3")

For more information on gTTS please visit https://pypi.org/project/gTTS/

dotnet sdk list and dotnet sdk latest

Can someone make .NET Core better with a simple global command? Fanie Reynders did and he did it in a simple and elegant way. I'm envious, in fact, because I spec'ed this exact thing out in a meeting a few months ago but I could have just done it like he did and I would have used fewer keystrokes! Last year when .NET Core was just getting started, there was a "DNVM" helper command that you could use to simplify dealing with multiple versions of the .NET SDK on one machine. Later, rather than 'switching global SDK versions,' switching was simplified to be handled on a folder by folder basis. That meant that if you had a project in a folder with no global.json that pinned the SDK version, your project would use the latest installed version. If you liked, you could create a global.json file and pin your project's folder to a specific version. Great, but I would constantly have to google to remember the format for the global.json file, and I'd constan

Top Tips For PCB Design Layout

Are you thinking about designing a printed circuit board? PCBs are quite complicated, and you need to make sure that the layout that you choose is going to operate as well as you want it to. For this reason, we have put together some top tips for PCB design layout. Keep reading if you would like to find out more about this. Leave Enough Space One of the most important design tips for PCB layout is that you need to make sure that you are leaving enough space between the components. While many people might think that packing components closely is the best route to take, this can cause problems further down the line. This is why we suggest leaving extra space for the wires that will spread. This way, you’ll have the perfect PCB design layout. Print Out Your Layout Struggling to find out if your components sizes match? Our next tip is to print out your layout and compare the printed version to your actual components. Datasheets can sometimes come with errors, so it doesn’t hurt to do
