IndoVMS: Indonesian voice messaging system

This paper focuses on developing IndoVMS, an application to dictate a short message for Android smartphones using Indonesian language. It is developed using Pocketsphinx and Java. Testing to five speakers, three males and two females, shows that the word error rate is so high for statistical language model and quite low for rule-based grammar. Investigating to three text corpora using three different smartphone devices shows that low performance device is feasible for both small vocabulary and small number of rules. But, the high performance device is still feasible for large grammar rules with both acceptable accuracy and response time.
