Convert math expression to spoken words in python

python

I need to convert a mathematical expression into spoken words text, e.g “x^2” to “x to the power of 2” let’s say, using python. For expression format, latex is a good but I do not succeed to convert latex format to text (I need only text, not voice - mp3). I found out about sayTex module in python but this are doing the opposite of what I need (convert spoken math into latex expression);

Are there some approaches that can I used to solve my problem?

I tried something with sympy but it failed:

from sympy import latex, sympify, pretty

def latex_to_text(latex_code):

    expr = sympify(latex_code, evaluate=False)

    text_representation = pretty(expr, use_unicode=True)

    return text_representation


latex_code = '\frac{1}{2} \times x^2'
human_readable_text = latex_to_text(latex_code)
print(human_readable_text)

Maybe the sympy is not the best tool for my problem

For converting LaTeX math expressions to spoken words, you can use the pyttsx3 library in Python. It’s a text-to-speech conversion library in Python. Here’s an example of how you can achieve this:

import sympy
import pyttsx3

def latex_to_spoken(latex_code):
    expr = sympy.sympify(latex_code)
    spoken_text = str(expr)
    return spoken_text

def speak_text(text):
    engine = pyttsx3.init()
    engine.say(text)
    engine.runAndWait()

latex_code = '\frac{1}{2} \times x^2'
spoken_text = latex_to_spoken(latex_code)
print(spoken_text)

# Uncomment the line below to have it spoken out loud (make sure your speakers are on)
# speak_text(spoken_text)

This script defines a function latex_to_spoken that converts a LaTeX expression to a spoken text using SymPy, and another function speak_text that uses pyttsx3 to speak the given text. You can uncomment the last line to have it spoken out loud.

Make sure to install sympy and pyttsx3 if you haven’t already:

pip install sympy pyttsx3

Keep in mind that the accuracy of the spoken text heavily depends on the complexity and format of the mathematical expressions. For more complex expressions, you might need a more sophisticated text-to-speech engine or specific natural language processing techniques tailored to math expressions.
