The US phoneset we use is the default one in festival, as described at http://www.festvox.org/bsv/c4711.html Any opening and closing parenthesis in `text` are removed, as they interfer with the Scheme expression syntax. Moreover double quotes are replaced by simple quotes because double quotes denotes utterances boundaries in festival. Parsing a ill-formed Scheme expression during post-processing (typically with unbalanced parenthesis) raises an IndexError. r) _preprocesslen_process _postprocess)r rPrQrRrFs r$_phonemize_auxzFestivalBackend._phonemize_auxsX"%% t99>>I}}T""  y%88 r(linecd|zdzS)z4Return the string `line` surrounded by double quotes"r'rYs r$_double_quotedzFestivalBackend._double_quotedsTzCr(ct|tdkrd}|ddddddS)z+Remove 'forbidden' characters from the line'r[())setreplacerFr\s r$_cleanedzFestivalBackend._cleanedsb t99C D||C$$,,S"55==c2FFLLNNNr(cbfd|D}dfd|DS)aReturns the contents of `text` formatted for festival input This function adds double quotes to begining and end of each line in text, if not already presents.
