synthesizer in windows sounds much better than in linux (python and pyttsx3)

I've made a simple text_to_speech function in python based on pyttsx3 library (in polish language).

import pyttsx3 as ttsengine = tts.init()engine.setProperty('rate', 130)engine.setProperty('voice', 'polish')def text_to_speech(text):    engine.say(text)    engine.runAndWait()

When I run this on windows the voice is tolerable, but in linux sounds teribble(windows 10 and ubuntu 18.04, pyttsx==2.9 on both machines).

I've also made for loop to print all available voices:

voices = engine.getProperty('voices')for voice in voices:    print("Voice:")    print("ID: %s" %voice.id)    print("Name: %s" %voice.name)    print("Age: %s" %voice.age)    print("Gender: %s" %voice.gender)    print("Languages Known: %s" %voice.languages)

Output in windows:

Voice: ID: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Speech\Voices\Tokens\TTS_MS_PL-PL_PAULINA_11.0 Name: Microsoft Paulina Desktop - Polish Age: None Gender: None Languages Known: [] Voice: ID: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Speech\Voices\Tokens\TTS_MS_EN-US_ZIRA_11.0 Name: Microsoft Zira Desktop - English (United States) Age: None Gender: None Languages Known: []

Output in linux:

Voice:ID: english-usName: english-usAge: NoneGender: maleLanguages Known: \[b'\\x02en-us'\]Voice:ID: polishName: polishAge: NoneGender: maleLanguages Known: \[b'\\x05pl'\]Voice:ID: brazilName: brazilAge: NoneGender: maleLanguages Known: \[b'\\x05pt-br'\]and a lot of other languages(...)

Is there a way to install other polish voices on linux version of pyttsx3 (or maybe other library)?
