[espeak-ng:master] New Comment on Pull Request #658 Changes for Shan language
You have used undefined phoneme
ɨ in shn_rules file.
Either use some other already defined phoneme (you can find definitions with command
egrep -r "^phoneme\s+\w+" phsource) or define
phoneme ɨ in ph_shan file. I don't recommend using non-Latin character for phoneme name though, because that would not follow Usenent/X-SAMPA phoneme naming convention used in espeak-ng. If you like, you can add
ipa ɨ entry in phoneme definition instead.
