In this post, we will learn how to make a simple CLI translator with Python. You can use it to learn a language or test translator service etc.
Before we start, please install Python and pip if you haven't yet. Then, read the docs for the packages we will use.
Then, save a file with the code below after you install and set up the Python dev env with pip with these.
$python -m venv <folder>
$cd <folder>
$source bin <folder>/activate
$pip install pyttsx3 deep_translator
You can use this command $touch test_text.py to make test_text.py file or something else for your file name.
import pyttsx3
from deep_translator import GoogleTranslator
def change_voice(engine, language, gender='VoiceGenderFemale'):
for voice in engine.getProperty('voices'):
if language in voice.languages and gender == voice.gender:
engine.setProperty('voice', voice.id)
return True
raise RuntimeError(
"Language '{}' for gender '{}' not found".format(language, gender))
engine = pyttsx3.init()
change_voice(engine, "en_US")
# change_voice(engine, "en_US", "VoiceGenderFemale")
rate = engine.getProperty('rate')
# print("rate")
# print(rate)
engine.setProperty('rate', 10)
volume = engine.getProperty('volume')
what_you_typed = input("Type something?\n")
engine.say(f"You typed {what_you_typed}")
engine.runAndWait()
translate_what_you_typed = input("Do you want to hear it in another language?\n")
if (translate_what_you_typed.lower().startswith("y")):
translated = GoogleTranslator(source='auto', target='pt').translate(what_you_typed)
print(translated)
change_voice(engine, "pt_BR")
engine.say(translated)
engine.runAndWait()
Then, you can test it with $python test_text.py and you will see the console messages similar to these.
Type something?
I like to use Python to learn how to code.
Do you want to hear it in another language?
y
You will be able to hear a text translated from what you typed.
If you want to, you can also set the voice to male or female with this.
# VoiceGenderFemale, VoiceGenderMale
change_voice(engine, "en_US", "VoiceGenderFemale")
change_voice(engine, "en_US", "VoiceGenderMale")
It doesn't work for all languages options. Therefore, you need to test what is available.
You can also update the target language to translate by editing the target part to what you want.
translated = GoogleTranslator(source='auto', target='pt').translate(what_you_typed)
The language options for the pyttsx3 and the deep_translator can be different. You can test some of them for your target language.
