Nous écrivons un robot de télégramme qui traduira des articles Internet en fichiers mp3

Bonjour à tous! Dans cet article, je partagerai mon implémentation d'un robot de télégramme capable de traduire des articles d'Internet en fichiers mp3. Pour cela, j'utiliserai python 3.6 et les bibliothèques associées. Alors, commençons.

telegram. , . pip, . , , :

pip install pyttsx3
pip install langdetect
pip install pydub
pip install bs4
pip install telebot
pip install PyTelegramBotAPI
