python自动化脚本-多语种磨耳朵

要学好一种语言，磨耳朵是非常必要的，只有长期让相同的声音不停刺激大脑，才能将语言听的懂，说的地道。

做一款好的听力产品，最重要的是找到高质量且具有性价比的语料库。Speechling作为专注于口语的非盈利平台，拥有丰富专业的资料可供学习和下载。

本文通过python自动化脚本，结合speechling的语料库，实现了英语、西班牙语、法语、日语、韩语、意大利语、葡萄牙语、德语和俄语等多语种沉浸式听力。通过电脑扬声器，播放设置语言的男声女声及其对应的汉语，且将对应的文字进行屏幕显示，效果如下：

首先，分析音频主页，获取支持的语种。如下图所示：

配置文件如下：

# 默认支持语言
#英语-english
#西班牙语-spanish
#法语-french
#日语-japanese
#韩语-korean
#意大利语-italian
#葡萄牙语-portuguese
#德语-german
#俄语-russian

[global]
lag = japanese

其次，分析类别页，获取所有的类别。如下图所示：

获取类别的python代码：

def get_classes_url(url):
    items = {}

    response = requests.get(url)
    response.encoding = 'utf-8'

    soup = BeautifulSoup(response.text, 'html.parser')

    all_classes = soup.find('div', class_='container-fluid')

    # 使用lambda函数动态查找具有特定href的a标签
    links = all_classes.find_all('a', href=lambda href: href and 'dictionary' in href)
    for link in links:
        items[link.text]=link['href']

    return items

再次，分析某一类目的所有条目页，获取条目名称和对应超链接。如下图所示：

获取条目的python代码：

def get_items_url(url):
    response = requests.get(url)
    response.encoding = 'utf-8'

    soup = BeautifulSoup(response.text, 'html.parser')

    items = {}

    # 使用lambda函数动态查找具有特定href的a标签
    links = soup.find_all('a', href=lambda href: href and 'how-to' in href)
    for link in links:
        items[link['href'][-4:]]=link.text

    return items

最后，分析具体的条目页，获取对应的音频链接。如下图所示：

播放mp3对应的URL的python代码：

def play_mp3_url(url):
    #print(url)

    response = requests.get(url)
    mp3_data = io.BytesIO(response.content)

    pygame.mixer.init()
    pygame.mixer.music.load(mp3_data)
    pygame.mixer.music.play()

    while pygame.mixer.music.get_busy():
        pygame.time.Clock().tick(10)

完整代码如下：

import requests
import io
import pygame
from bs4 import BeautifulSoup
import configparser

def play_mp3_url(url):
    #print(url)

    response = requests.get(url)
    mp3_data = io.BytesIO(response.content)

    pygame.mixer.init()
    pygame.mixer.music.load(mp3_data)
    pygame.mixer.music.play()

    while pygame.mixer.music.get_busy():
        pygame.time.Clock().tick(10)

def get_items_url(url):
    response = requests.get(url)
    response.encoding = 'utf-8'

    soup = BeautifulSoup(response.text, 'html.parser')

    items = {}

    # 使用lambda函数动态查找具有特定href的a标签
    links = soup.find_all('a', href=lambda href: href and 'how-to' in href)
    for link in links:
        items[link['href'][-4:]]=link.text

    return items

def get_classes_url(url):
    items = {}

    response = requests.get(url)
    response.encoding = 'utf-8'

    soup = BeautifulSoup(response.text, 'html.parser')

    all_classes = soup.find('div', class_='container-fluid')

    # 使用lambda函数动态查找具有特定href的a标签
    links = all_classes.find_all('a', href=lambda href: href and 'dictionary' in href)
    for link in links:
        items[link.text]=link['href']

    return items

#英语：english
#俄语：russian
config = configparser.ConfigParser()
config.read('./config.ini')
lag=config['global']['lag']

#列表
url = 'https://speechling.com/zh/dictionary/'+lag+'/all'
class_items = get_classes_url(url)
for class_name, class_url in class_items.items():
    print(class_name)
    items = get_items_url('https://speechling.com/zh'+class_url)
    for num, text in items.items():
        new_num = int(num) + 1
        #需要做url变换
        play_mp3_url("https://speechling.com/static/audio/female/"+lag+"/"+lag+"_" + str(new_num) + ".mp3")
        play_mp3_url("https://speechling.com/static/audio/male/"+lag+"/"+lag+"_" + str(new_num) + ".mp3")
        play_mp3_url("https://speechling.com/static/audio/female/mandarins/mandarins_" + str(new_num) + ".mp3")
        # play_mp3_url("https://speechling.com/static/audio/male/mandarins/mandarins_" + num + ".mp3")
        print(text)
