+# Pronunciation rules for isiZulu.
+#
+# Author: mjansche@google.com (Martin Jansche)
+#
+# These rules transcribe isiZulu into the phoneme inventory used within the
+# NCHLT Speech Corpus (https://sites.google.com/site/nchltspeechcorpus/home).
+#
+# The rules were tested using the NCHLT-inlang isiZulu pronunciation dictionary
+# (http://rma.nwu.ac.za/index.php/resource-catalogue/nchlt-inlang-dictionaries.html).
+# They correctly account for all 15,000 entries in the dictionary.
+#
+# The NCHLT 2013 phone set does not indicate tone in any way. Transcription of
+# tone is out of scope without a dictionary, since tone is generally not
+# indicated in the orthography. Nasal clicks are not treated as separated
+# phonemes in the NCHLT 2013 phone set and are transcribed as a sequence of
+# nasal plus click instead.
+#
+# One minor notational deviation from the NCHLT 2013 phone set is that we use a
+# tie bar within the complex (depressor) clicks, e.g. ɡ\u0361ǀ instead of ɡǀ, to
+# avoid ambiguity and make the phoneme inventory uniquely decodable.
