espeak-ng and espeak_wrapper on windows, omitted letters

[houkman]

I noticed that espeak-ng (1.52-dev) launched from the console produces wrong output (phonemization and sound). Some letters are completely omitted. The problem is already known: https://sourceforge.net/p/espeak/bugs/125/. Changing the character encoding in the console to UTF-8 (chcp 65001) does not help. The same thing happens with espeak_wrapper.py. For example: for polish word - "źrebię" ("foal" - in english), after running in python:

>>> exec(open("espeak_wrapper.py", encoding="utf-8").read(), globals())
>>> from TTS.tts.utils.text.phonemizers import ESpeak
>>> phonemizer = ESpeak("pl")
>>> phonemizer.phonemize("źrebię", separator="")

result is: "rˈɛbʲi" but it should be: "ʑrˈɛbjɛ"
(referring to https://odo.lv/Espeak?eslang=-vpl&speed=160&output=-w&debug=-x&text=źrebię&formmethod=get)

The letters "ź" and "ę" are completely omitted. I think this also applies to languages ​​other than polish. I'm not a python programmer, but checking def _espeak_exe in espeak_wrapper.py it looks like the text that is phonemized is readed from the console. I think this is the wrong approach and on windows it should be read from a UTF-8 encoded file, example:

espeak-ng -vpl --ipa -f utf8_text.txt

I modified espeak_wrapper.py (def phonemize_espeak) for my needs from:

if tie:
	args.append("--tie=%s" % tie)

args.append(text)
# compute phonemes

to:

if tie:
	args.append("--tie=%s" % tie)

UTF8filepath = "p:\\temp\\phonemes.txt"
UTF8file = open(UTF8filepath, "w", encoding="utf-8")
UTF8file.write(text)
UTF8file.close()

args.append("-f")
args.append(UTF8filepath)
# compute phonemes

and now phonemize works properly. As I said, I'm not a python programmer, everything I did is based on google. Someone should take a closer look at this. I'm on windows 10, python v3.11, coqui TTS-0.22.0.

This repo is not maintained anymore, but I just fixed this in our fork (available via pip install coqui-tts) by having Espeak read the input from a temporary file. Thank you for spotting and reporting it!
