Speech production is an extremely complex process, whose result depends on many variables at different levels, including sociolinguistic factors (e.g., level of education, linguistic context, and dialectal differences) and morphological issues (e.g., vocal tract length and shape or the dynamic configuration of the articulatory organs). These multiple influences will be simultaneously present in each speech act and some or all of them will contain specificities of the speaker. Hence, it is needed to clarify and clearly distinguish the different levels and sources of speaker information that should be extracted to model speaker individualities.
