Toolkit for TDOA feature #14

Closed glynpu closed 7 years ago

glynpu commented 7 years ago

Hi Srikanth,

Could I know which toolkit do you use to extract TDOA feature?

I have installed a Toolkit called BeamformIt implemented by Xavier Anguera . But the output TDOA is in plain text format, which is in different format with the TDOA example you provided. Actually, I have no idea what format it is in.

Best wishes, Liyong Guo

Hi,

You need to convert the TDOA features to HTK format just like the MFCC files.

Thanks, Srikanth

Hi Srikanth,

Now there is a small problem about the conversion.

Could you give me a clue how to convert the plain text TDOA to HTK format?

My idea is using HCopy command, but I don't know the exact process.

Now the TDOA is in the the following format:

0 -> 0 1.000000 0 1.000000 0 1.000000 -2 0.132788 0 1.000000 -2 0.157925 0 1.000000 0 1.000000 250 -> 0 0.081363 0 0.088067 -5 0.125728 -3 0.133382 0 1.000000 -2 0.158627 0 0.091988 0 0.089718 500 -> 0 0.065306 0 0.077321 -5 0.111814 -3 0.132347 0 1.000000 -2 0.162307 0 0.093127 0 0.102211 750 -> 0 0.066661 0 0.068743 -5 0.100992 -2 0.120905 0 1.000000 -2 0.163557 0 0.093942 0 0.090335 1000 -> 0 0.064726 7 0.107366 -5 0.117871 -3 0.130984 0 1.000000 -2 0.180463 0 0.090841 0 0.081424

Aha, the writehtk function in Voicebox toolkit meets the requirement.
