Text to speech model in Python

In this tutorial, we will learn how we can create a text to speech model in Python?
Submitted by Abhinav Gangrade, on June 04, 2020

Text to speech model is a small application or bot which converts the given text into speech.

The module that we use for text to speech conversion: pyttsx3

pyttsx3 is a text-to-speech conversion library in Python. It is very easy to use tool which converts the entered text into speech.

Download the module:

pip install pyttsx3 (In your terminal or command prompt)

If you are using Pycharm User: Go to the project interpreter and install the module.

The various functions that we will use in this model are,

  • engine=pyttsx3.init(): The init function is the main function, we have to use this function every time. This function initializes the connection and creates an engine and we can perform all the things on the engine created by the .init() function
  • engine.say(text): This function will convert the text to speech (text is the input from the user)
  • engine.runAndWait(): This function will make the speech audible in the system, if you don't write this command then the speech will not be audible to you.
  • engine.setProperty(): This method sets different properties of the model.
    engine.getProperty(): This method is used to get the details with the help of this function.
  • voice: If we want the Voices and ascent of the model, we can get it with the help of the voice method.

Syntax:

voice=engine.getProperty("voices")
print("voice")

Output:

<pyttsx3.voice.Voice object at 0x7f16507656d8>]

This is the list of various voices, Now if you want to know which accent is there in this list so we can access that with the help of this following code:

for i in voice:
  print(i.id)

So the various ascents are:

['afrikaans', 'aragonese', 'bulgarian', 'bosnian', 'catalan', 
'czech', 'welsh', 'danish', 'german', 'greek', 'default', 
'english', 'en-scottish', 'english-north', 'english_rp', 
'english_wmids', 'english-us', 'en-westindies', 'esperanto', 
'spanish', 'spanish-latin-am', 'estonian', 'persian', 
'persian-pinglish', 'finnish', 'french-Belgium', 'french', 
'irish-gaeilge', 'greek-ancient', 'hindi', 'croatian', 
'hungarian', 'armenian', 'armenian-west', 'indonesian', 
'icelandic', 'italian', 'lojban', 'georgian', 'kannada', 
'kurdish', 'latin', 'lingua_franca_nova', 'lithuanian', 
'latvian', 'macedonian', 'malayalam', 'malay', 'nepali', 
'dutch', 'norwegian', 'punjabi', 'polish', 'brazil', 'portugal', 
'romanian', 'russian', 'slovak', 'albanian', 'serbian', 'swedish', 
'swahili-test', 'tamil', 'turkish', 'vietnam', 'vietnam_hue', 
'vietnam_sgn', 'Mandarin', 'cantonese']

Now if I want to set the ascent so I will do like:

engine.setProperty("voice",voice[15].id)

It means the 15th ascent.

Now if we want to set the speed of the speech:

engine.setProperty("rate",<The speed you want>)

Program:

# importing the package
import pyttsx3

engine=pyttsx3.init()

text=input("Enter the text that you wanted to convert into speech")

s=engine.getProperty("voices")
engine.setProperty("voice",s[0].id)
engine.setProperty("rate",150)
engine.say(text)
engine.runAndWait()

Note: Do all the setProperty and getProperty stuff before .say() and .runAndWait() otherwise it will not show the results as you want.

Errors:

Many of you can get an error or sometimes the speech will not be audible.
