How to calculate Time of Speech Codec in Tems Discovery Device?

Dear experts
Could you pls share how to calculate the time of each speech codec ( voice test case ) in Tems Discovert Device ? Ex: AMR 12.2kbps has xxx (s) throughout the whole testing time …In Nemo, we can do it easily
In TDD, we have Speech Codec Main Rate DL that have the samples ( but not the time )
Thank a lot
