Convert Text to Speech in Python

Learn how to convert your Text into Voice with Python and Google APIs

Text to speech is a process to convert any text into voice. Text to speech project takes words on digital devices and convert them into audio with a button click or finger touch. Text to speech python project is very helpful for people who are struggling with reading.

Project Prerequisites

To implement this project, we will use the basic concepts of Python, Tkinter, gTTS, and playsound libraries.

  • Tkinter is a standard GUI Python library that is one of the fastest and easiest ways to build GUI applications using Tkinter.
  • gTTS (Google Text-to-Speech) is a Python library, which is a very easy library that converts the text into audio.
  • The playsound module is used to play audio files. With this module, we can play a sound file with a single line of code.

To install the required libraries, you can use pip install command:

pip install tkinter
pip install gTTS
pip install playsound

Text to Speech Python Project

The objective of this project is to convert the text into voice with the click of a button. This project will be developed using Tkinter, gTTs, and playsound library.

In this project, we add a message which we want to convert into voice and click on play button to play the voice of that text message.

  • Importing the modules
  • Create the display window
  • Define functions

So these are the basic steps that we will do in this Python project. Let’s start.

1. Import Libraries

Let’s start by importing the libraries: tkinter, gTTS, and playsound

from tkinter import *
From gtts import gTTS
From playsound import playsound

2. Initializing window

root = Tk()
geometry root.("350x300") 
root.configure(bg='ghost white')
root.title("DataFlair - TEXT TO SPEECH")
  • Tk() to initialized tkinter which will be used for GUI
  • geometry() used to set the width and height of the window
  • configure() used to access window attributes
  • bg will used to set the color of the background
  • title() set the title of the window
Label(root, text = "TEXT_TO_SPEECH", font = "arial 20 bold", bg='white smoke').pack()
Label(text ="DataFlair", font = 'arial 15 bold', bg ='white smoke' , width = '20').pack(side = 'bottom')

Msg = StringVar()
Label(root,text ="Enter Text", font = 'arial 15 bold', bg ='white smoke').place(x=20,y=60)

entry_field = Entry(root, textvariable = Msg ,width ='50')
entry_field.place(x=20,y=100)

Label() widget is used to display one or more than one line of text that users can’t able to modify.

  • root is the name which we refer to our window
  • text which we display on the label
  • font in which the text is written
  • pack organized widget in block
  • Msg is a string type variable
  • Entry() used to create an input text field
  • textvariable used to retrieve the current text to entry widget
  • place() organizes widgets by placing them in a specific position in the parent widget

3. Function to Convert Text to Speech in Python

def Text_to_speech():
    Message = entry_field.get()
    speech = gTTS(text = Message)
    speech.save('DataFlair.mp3')
    playsound('DataFlair.mp3')
  • Message variable will stores the value of entry_field
  • text is the sentences or text to be read.
  • lang takes the language to read the text. The default language is English.
  • slow use to reads text more slowly. The default is False.

As we want the default value of lang, so no need to give that to gTTS.

  • speech stores the converted voice from the text
  • speech.save(‘DataFlair.mp3’) will saves the converted file as DataFlair as mp3 file
  • playsound() used to play the sound

4. Function to Exit

def Exit():
    root.destroy()

root.destroy() will quit the program by stopping the mainloop().

5. Function to Reset

def Reset():
    Msg.set("")

Reset function set Msg variable to empty strings.

6. Define Buttons

Button(root, text = "PLAY", font = 'arial 15 bold' , command = Text_to_speech ,width = '4').place(x=25,y=140)

Button(root, font = 'arial 15 bold',text = 'EXIT', width = '4' , command = Exit, bg = 'OrangeRed1').place(x=100 , y = 140)

Button(root, font = 'arial 15 bold',text = 'RESET', width = '6' , command = Reset).place(x=175 , y = 140)

Button() widget used to display button on the window

 

root.mainloop()

root.mainloop() is a method that executes when we want to run our program.

Summary

We have successfully developed the text to speech python project. We used the popular tkinter library for rendering graphics on a display window, gTTs (google text to speech) library to convert text to voice, and playsound library to play that converter voice from the text.

    The project doesn’t allow the play button to be used more than once on clicking. Once the play is clicked, second attempt doesn’t work. I receive the following error on running the actual source code.

    Exception in Tkinter callback
    Traceback (most recent call last):
    File “C:\Users\aashi\anaconda3\lib\tkinter\__init__.py”, line 1705, in __call__
    return self.func(*args)
    File “Text-to-Speech.py”, line 43, in Text_to_speech
    speech.save(‘DataFlair.mp3’)
    File “C:\Users\aashi\anaconda3\lib\site-packages\gtts\tts.py”, line 294, in save
    with open(str(savefile), ‘wb’) as f:
    PermissionError: [Errno 13] Permission denied: ‘DataFlair.mp3’

    • DataFlair Team says:

      Yeah… You have to rerun the project to use the app again. It is because we are saving the mp3 file as dataflair.mp3 and if we use the play button twice from the same window then it will again try to create a new mp3 file with the same name which is not possible, so it will try to replace the existing dataflair.mp3 file which is not allowed and that’s why it is showing permission denied.

  2. Naveen Nagar says:

    is there any tutorial on speech to text using python ?

  3. Joseph says:

    yeah. i faced it too. in the reset button, add a simple command to delete the existing dataflare.mp3 file.
    so when u press the reset button the mp3 file will be deleted and you don’t get the above error.

  4. A says:

    If like me, you don’t want a reset button, you can simply add a line after “Playsound(‘DataFlair.mp3’)” that deletes the file, therefore allowing you to repeatedly change what you’re writing in the TTS without having to reset at all.

    • DataFlair Team says:

      yeah, That’s another option, and yes, based on the requirements we can update this python project as we have hand-coded the logic.

  5. Sandhya says:

    Sir i am getting the same error. Plesae provide the solution to overcome this problem.

    • Satish Narasimhan says:

      You would need to import os library and add the following line in def Text_to_speech(): after playsound(‘T2S.mp3’)
      os.remove(‘T2S.mp3’)

      Worked for me

  6. sanjeev prajapati says:

    sir , when i clicking on reset button, they are giving Permission denied.
    then ,how can remove Permission denied to play more than one string in single of running program?
