This paper describes the work carried out to select the
most suitable set of Sublexical Units for Continuous
Speech Recognition of Basque. Even if there are several
dialects in Basque, only one of them has been used to
choose the preliminary set of sounds. Bearing in mind
this aim, a wide experimentation has been carried out to
select Context Independent Phone-Like Units. Then, in
order to obtain robust acoustic models for the language,
the units have been evaluated with most of the dialectal
variants of Basque. Finally, Decision-Trees based
Context Dependent Sublexical Units are selected. For
building the trees the classical methodology of Bahl and
the efficient Growing and Pruning algorithm have been
used.
