voice = Voice(lang="en")
print(voice.to_phonems("second").phonemes_str)

Expected behavior

Comments

Interestingly, it works when I change language to French or when I try the word corner in English.

BTW, shouldn't it be to_phonemes instead of to_phonems? The English singular is a phoneme.

I'll investigate about the bug, but you're right about the Phonemes things (https://en.wiktionary.org/wiki/phoneme#Noun). I'll change it right away.

Thanks for the level of professionalism of your bug reports btw, i really appreciate it!

Hah, thanks! I picked it up from Joel on Software.

Thanks for fixing spelling - only one small correction left (see #6).

Merged. Regarding the original bug, could you print out the string of phonemes returned by espeak, before it's "parsed" by the PhonemList class? I might have an idea.

Here:

s       107
e       53       0 105 80 81 100 81
k       110
@       37       0 84 80 78 100 78
n       91      100 73

d       70
_       350
_       1

The blank line is causing the problems.

The problem is once again Windows-specific. Newlines in Windows are created with CRLF line breaks, which include \r character. Stripping the troublesome line fixes the problem.
