- This label type occurs a special kind of label file which is created automatically during
recording with EUROPEC (see 3 below). It contains sequence beginning (in
samples), sequence end, input gain or recording, minimum sample value, maximum
sample value, orthographic text. The text represents the prompt, not necessarily what
the speaker actually uttered. In the case of two-channel recordings, each LBR label
can be followed by an LB2: sequence (second channel speech file) or LBL:
(laryngograph on 2nd channel) that contains the same information: beginning value (in
samples), end value, input gain or recording, minimum sample value, maximum
sample value. A mnemonic indicating other sensors (e.g. LBN (nasal), LBF (airflow),
LBT (tongue contact) etc. can be defined if required. The purpose of this label file is to
call up individual sections of larger files. The LBR labels represent ``items'' which can
be specified when a signal file is opened.
- Orthographic labels produced manually. These labels attempt to represent what the
speaker actually produced, with indications of pauses, hesitations, repetitions etc.
Often, an EXT: line and a CMT: line are needed.
- Broad Phonetic labels, produced manually or by means of (semi-) automatic label
- Acoustic-phonetic labels (subdivisions of broad phonetic segments) produced
manually or by means of semi-automatic labelling.
- Prosodic labels, produced manually or by means of (semi-) automatic labelling.
