 The script performs diarization using x-vectors(TDNN,ECAPA-TDNN) on the AMI mix-headset data. We demonstrate the use of different clustering methods: AHC, spectral.
 
 ## How to Run
+### prepare annotations and audios
+Download AMI corpus, You need around 10GB of free space to get whole data
+The signals are too large to package in this way, so you need to use the chooser to indicate which ones you wish to download
+
+```bash
+## download  annotations
+wget http://groups.inf.ed.ac.uk/ami/AMICorpusAnnotations/ami_public_manual_1.6.2.zip && unzip ami_public_manual_1.6.2.zip
+```
+
+then please follow https://groups.inf.ed.ac.uk/ami/download/ to download the Signals:
+1) Select one or more AMI meetings: the IDs please follow ./ami_split.py
+2) Select media streams: Just select Headset mix
+
+### start running
 Use the following command to run diarization on AMI corpus.
-`bash ./run.sh` 
+```bash
+./run.sh  --data_folder ./amicorpus  --manual_annot_folder ./ami_public_manual_1.6.2
+```
 
 ## Results (DER) coming soon! :)
