Hello,
I've processed my posterior .rec file with the following command;

./HList -r $rec_file

I obtain a matrix with 3 states per fonetic unit and per frame. Please, could you help to know if matrix format is:
frame1        unit1(state1) unit1(state2) unit1(state3) unit2(state1) unit2(state2) unit2(state3) ...

or:
frame1        unit1(state1) unit2(state1) unit1(state2) unit2(state2) unit1(state3) unit2(state3)...

So, each row is it shorted by fonetic unit or state?

Thanks in advance.

Hi, I also have the exact same question. I am looking to sum up the posteriors to 46 classes from the 138 in the file output by the CZ recogniser.

Hope to hear back!

Hi, it is sorted by phonetic unit.

unit1_state1 unit1_state2 unit1_state3 unit2_state1 ...

The final 3 outputs are for parts of audio with no phonetic labeling or silence (marked as ‘other’).
