Label types

 

LBR:

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.

LBO:

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.

LBB:

Broad Phonetic labels, produced manually or by means of (semi-) automatic label alignment.

LBA:

Acoustic-phonetic labels (subdivisions of broad phonetic segments) produced manually or by means of semi-automatic labelling.

LBP:

Prosodic labels, produced manually or by means of (semi-) automatic labelling.
