Python|将图像转换为文本，然后转换为语音

我们的目标是将给定的文本图像转换为文本字符串，将其保存到文件中，并通过音频听到图像中写入的内容。

为此，我们需要导入一些库

  1. Pytesseract(Python-tesseract) ：它是 google 赞助的Python光学字符识别 (OCR) 工具。
  2. pyttsx3 ：它是一个离线的跨平台文本到语音库
  3. Python Imaging Library (PIL) ：它为您的Python解释器添加了图像处理功能
  4. Googletrans ：它是一个免费的Python库，实现了 Google Translate API。

例子： 

Input : We Have an image with some text 

Output: THE TEXT FROM THE IMAGE IS EXTRACTED AND A VOICE WILL SPEAK THE TEXT
      

          This is the first line of
           this text example.

          This is the second line
           of the same text.

       Translated(src=en, dest=de, text=Dies ist die erste Zeile von

           Dieses Textbeispiel.

            Dies ist die zweite Zeile
            desselben Textes., pronunciation=None, extra_data="{'translat..."

代码：将文本转换为语音的Python代码

# import the following libraries
# will convert the image to text string
import pytesseract      
  
# adds image processing capabilities
from PIL import Image    
  
 # converts the text to speech  
import pyttsx3           
  
#translates into the mentioned language
from googletrans import Translator      
  
 # opening an image from the source path
img = Image.open('text1.png')     
  
# describes image format in the output
print(img)                          
# path where the tesseract module is installed
pytesseract.pytesseract.tesseract_cmd ='C:/Program Files (x86)/Tesseract-OCR/tesseract.exe'   
# converts the image to result and saves it into result variable
result = pytesseract.image_to_string(img)   
# write text in a text file and save it to source path   
with open('abc.txt',mode ='w') as file:     
      
                 file.write(result)
                 print(result)
                   
p = Translator()                      
# translates the text into german language
k = p.translate(result,dest='german')      
print(k)
engine = pyttsx3.init()
  
# an audio will be played which speaks the test if pyttsx3 recognizes it
engine.say(k)                             
engine.runAndWait()

注意：我们可以将文本转换为任何所需的语言。例如日语、俄语、印地语。但唯一的条件是 googletrans 应该识别目标语言。此外，pyttsx3 只会说它所识别的语言。
