Navigating Through Sound: Bypassing Audio CAPTCHAs with Python

Introduction

Phase 1: Setting up the Environment

import asyncio

from playwright.async_api import async_playwright

import speech_recognition as sr

from pydub import AudioSegment

import os

import httpx

Phase 2: Downloading the Audio CAPTCHA

async def download_audio(audio_url):

    async with httpx.AsyncClient() as client:

        resp = await client.get(audio_url)

        if resp.status_code == 200:

            with open('audio.mp3', 'wb') as f:

                f.write(resp.content)

            return True

    return False

Phase 3: Converting Audio to Text

async def convert_audio_to_text():

    wav_file = "temp_audio.wav"

    audio_segment = AudioSegment.from_mp3("audio.mp3")

    audio_segment.export(wav_file, format="wav")

    recognizer = sr.Recognizer()

    with sr.AudioFile(wav_file) as source:

        audio = recognizer.record(source)

        try:

            text = recognizer.recognize_google(audio)

            return text

        except sr.UnknownValueError:

            print("Sorry, I could not understand the audio.")

        except sr.RequestError as e:

            print(f"Could not request results from Google Speech Recognition service; {e}")

    os.remove(wav_file)  # Cleanup after conversion

    return None

Phase 4: Automating CAPTCHA Solving

async def solve_captcha():

    async with async_playwright() as p:

        browser = await p.chromium.launch(headless=False)

        page = await browser.new_page()

        await page.goto('https://www.google.com/recaptcha/api2/demo')



        # Initial CAPTCHA interaction

        await page.click('iframe[title="reCAPTCHA"]')

        await asyncio.sleep(2)  # Wait for CAPTCHA challenge



        # Solve audio CAPTCHA if necessary

        # Additional code here to handle audio CAPTCHA logic...



        await browser.close()



asyncio.run(solve_captcha())
