Try

$ ./configure && make
$ sudo make install
$ cd testsuite
$ make lex_lookup
$ sudo cp lex_lookup /usr/local/bin

I think you're using the older t2p method and everything in Epitran is now set up to use the newer lex_lookup method.

There seems to be an integration bug with flite but I am not able yet to determine where it comes from, because on some of our machines with same versions of flite and epitran it works fine, while on others it does not.

I see no option to re-open the issue myself, so I can probably submit a new one.

Here's how I reproduced the problem.

I have installed the recommended flite version

wget http://www.festvox.org/flite/packed/flite-2.0/flite-2.0.0-release.tar.bz2 -O flite-2.0.0-release.tar.bz2 
tar xvfj flite-2.0.0-release.tar.bz2 
rm flite-2.0.0-release.tar.bz2
cd flite-2.0.0-release
./configure && make
make install 
sudo cp bin/t2p /usr/local/bin

I have installed the latest stable epitran version:

$ pip list | grep epitran
epitran                 1.8

And tried with English

$ python
Python 3.6.9 (default, Oct  8 2020, 12:12:24)
[GCC 8.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import epitran
>>> t = epitran.Epitran("eng-Latn")
>>> t.transliterate("shot")

and got

WARNING:root:lex_lookup (from flite) is not installed.

Traceback (most recent call last):
  File "reproduce.py", line 3, in <module>
    t.transliterate("shot")
  File "/home/m.gawinecki/virtualenv/la-aliasproc/lib/python3.6/site-packages/epitran/_epitran.py", line 62, in transliterate
    return self.epi.transliterate(word, normpunc, ligatures)
  File "/home/m.gawinecki/virtualenv/la-aliasproc/lib/python3.6/site-packages/epitran/flite.py", line 94, in transliterate
    acc.append(self.english_g2p(chunk))
  File "/home/m.gawinecki/virtualenv/la-aliasproc/lib/python3.6/site-packages/epitran/flite.py", line 214, in english_g2p
    arpa_text = arpa_text.splitlines()[0]
IndexError: list index out of range

I guess first line is the problem:

from epitran.

Right, installing lex_lookup helped a lot. Thank you.
