How to fix pronunciation errors

Error in pronunciation (in the text-to-phoneme part) can be fixed by calling ​ALTextToSpeech.addToDictionary. This function stores the dictionary in /home/nao/.config/tts/nuance/cs_CZ/rulesets.rst:

[header]
language = czc
charset = utf-8
[data]
/Ou/   -->   "\e\\toi=lhp\\o&u\e\\toi=orth\\"
/www/   -->   "\e\\toi=lhp\\vE:vE:vE:\e\\toi=orth\\"

You can also directly edit this file and then recompile the dictionary e.g. by calling

qicli call ALTextToSpeech.deleteFromDictionary unexisting

The search string is a ​PCRE regular expression. Current description (possibly newer than in Pepper) can be found at the ​Nuance pages.
