Format NXT (exemple segments)

<?xml version="1.0" encoding="ISO-8859-1"?>
<nite:root nite:id="ES2002a.A.segs" xmlns:nite="http://nite.sourceforge.net/">
  <segment nite:id="ES2002a.sync.1"
           transcriber_start="12.34" transcriber_end="14.56"
           participant="A">
    <nite:child href="ES2002a.A.words.xml#id(ES2002a.w.12)..id(ES2002a.w.27)"/>
  </segment>
  ...
</nite:root>

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("ami_public_manual_1.6.2/segments/*.segments.xml"):
    root = ET.parse(seg_xml).getroot()
    meeting, spk, _ = seg_xml.split("/")[-1].split(".", 2)
    for seg in root.findall("segment"):
        t0 = float(seg.attrib.get("transcriber_start", seg.attrib.get("starttime", 0)))
        t1 = float(seg.attrib.get("transcriber_end",   seg.attrib.get("endtime",   0)))
        if t1 > t0:
            print(f"SPEAKER {meeting} 1 {t0:.3f} {t1-t0:.3f} <NA> <NA> {spk} <NA> <NA>")
