Python 3.10.8中googletrans库触发AttributeError问题求助

问题概述 #

编写了集成语音识别与印地语转英语翻译的Python代码，运行翻译模块时触发AttributeError: 'NoneType' object has no attribute 'group'，使用Python版本为3.10.8。

原始代码 #

import speech_recognition as sr
from googletrans import Translator

def Listen():
    r = sr.Recognizer()

    with sr.Microphone() as source:
        print("Listening...")
        r.pause_threshold = 1
        audio = r.listen(source,0,6)

    try:
        print("Regognizing...") 
        query = r.recognize_google(audio, language = "hi")

    except: 
        return ""

    query = str(query).lower()
    return query

def TranslationHintoEng(Text):
    line = str(Text)
    translate = Translator()
    result = translate.translate(line)
    data = result.text
    print(f"You : {data}")
    return data

TranslationHintoEng("कैसा है जारविस मेरी आवाज आ रही है")

解决方案 #

该错误源于googletrans最新版本的Token获取机制失效，Google翻译接口更新后，旧版逻辑无法匹配新的页面结构。提供两种修复方案：

方案1：降级到稳定版googletrans #

卸载当前版本并安装4.0.0-rc1版本，该版本适配了当时的Google翻译接口：

pip uninstall googletrans -y
pip install googletrans==4.0.0-rc1

替换后重新运行代码即可正常翻译。

方案2：使用官方Google Cloud Translation API #

若需要长期稳定的翻译服务，推荐使用Google官方提供的Translation API（需注册Google Cloud账号并启用对应服务，配置API密钥）：

from google.cloud import translate_v2 as translate

def TranslationHintoEng(Text):
    # 初始化翻译客户端，可通过环境变量或密钥文件配置认证
    translate_client = translate.Client()
    # 指定源语言为印地语(hi)，目标语言为英语(en)
    result = translate_client.translate(Text, target_language='en', source_language='hi')
    data = result['translatedText']
    print(f"You : {data}")
    return data

TranslationHintoEng("कैसा है जारविस मेरी आवाज आ रही है")
