Phonetic labelling is the assignment of a phonetic symbol to a speech signal segment corresponding to a linguistic unit. Manual labelling of speech is tremendously labour-intensive, but we still cannot do completely without. One of the problems in manual labelling is the establishment of objective labelling criteria; in the case of (semi-)automatic labelling this translates into the question as to the concept validity of the labels. This paper describes a study into formulation of reliable criteria. Two labellers processed the same speech fragment, using provisional criteria. Comparison of the results led to formulation of additional labelling criteria and modification of the old ones. In order to check the new set of criteria, the same two labellers processed a new speech fragment of the same speaker and two speech fragments of another speaker.
