+Text normalization for a TTS
+============================
+
+The task is to write a Thrax grammar for normalizing text for a
+text-to-speech system, i.e. the text should be converted to a form
+closer to speech (but without phonetic transcription).
+
+For instance, "I bought 21 books from prof. Smith" should
+be transformed into "i bought twenty-one books from professor smith"
+
+You should:
+
+- convert numbers 0-99 into words
+- convert Roman numbers I-X into adjectives (the first, the second, etc.)
+- expand abbreviations: "e.g." ("for example"), , "prof." ("professor"), "dr." ("doctor"),
+  "p." ("page"), "pp." ("pages")
+- remove punctuations (except for hyphen)
+- lower-case everything
+
