+# Results for mucs hi-en and bn-en
+
+This page shows the WERs for the code switched test corpus of MUCS hi-en and bn-en.
+
+## using conformer ctc
+
+The following results are obtained with run.sh
+
+Specify the language through dataset arg (hi-en or bn-en)
+LM is trained using kenlm, with the training corpus
+
+Here are the results with different decoding methods
+
