Change pyttsx3 language


When trying to use pyttsx3 I can only use English voices. I would like to be able to use Dutch as well.

I have already installed the text to speech language package in the windows settings menu. But I can still only use the deafaut english voice.

How can I fix this?


Solution

  • If you want to change a language you need to change to another "voice" that supports your language.

    1. To see which voices/languages are installed you can list them like this:
    import pyttsx3
    
    engine = pyttsx3.init()
    
    for voice in engine.getProperty('voices'):
        print(voice)
    
    1. No you can change to your favorite voice like this:
    engine.setProperty('voice', voice.id)
    

    I personally use this helper function I mentioned here also

    # language  : en_US, de_DE, ...
    # gender    : VoiceGenderFemale, VoiceGenderMale
    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))
    

    And finally, you can use it like this (if language and gender are installed):

    import pyttsx3
    
    engine = pyttsx3.init()
    change_voice(engine, "nl_BE", "VoiceGenderFemale")
    engine.say("Hello World")
    engine.runAndWait()
