Pour construire un RTTM standard à partir des segments NXT :
from glob import glob
from xml.etree import ElementTree as ET
NS = {"nite": "http://nite.sourceforge.net/"}
for seg_xml in glob("ICSI/Segments/*.segs.xml"):
root = ET.parse(seg_xml).getroot()
meeting = root.attrib["{http://nite.sourceforge.net/}id"].split(".")[0]
for seg in root.findall("segment"):
spk = seg.attrib["participant"]
t0 = float(seg.attrib["starttime"])
t1 = float(seg.attrib["endtime"])
print(f"SPEAKER {meeting} 1 {t0:.3f} {t1-t0:.3f} <NA> <NA> {spk} <NA> <NA>")
