In this paper a Bottom-Up (BU) method of obtaining
information about pronunciation variation is proposed. BU
transcriptions (Tbu) were obtained by letting a CSR decide for
each phone whether it was deleted or not. The Tbu were
compared to transcriptions obtained automatically with a Top-
Down method, and the agreement appeared to be very high.
Subsequently, the Tbu were aligned with canonical reference
transcriptions (Tref) and on the basis of this alignment, deletion
rules were derived. The BU rules were employed to generate
variants which were used in recognition experiments. The
results of these recognition experiments show that the
information about pronunciation variation obtained using the
BU method can be used to improve recognition performance.
