Watson Speech To Text service works faster for which type of audio file?

I have tried the Watson Speech to Text API for MP3 as well as WAV files. As per my observation, the same length of audio takes less time if its given in MP3 format as compared to WAV. 10 consecutive API calls with different audios took on an average 8.7 seconds for MP3 files. On the other hand the same input in WAV format took average 11.1 seconds. Does the service response time depend on the file type? Which file type is recommended to use to obtain the results faster?
