Although most psycholinguistic models consider phonological and phonetic planning as distinct utterance planning processes, the distinction between phonological and phonetic encoding is still debated along with the planning units and size at play in utterance encoding processes. I will first review the empirical evidence from psycholinguistic, neuropsychological and neuroimaging studies in favour and against the phonological-phonetic distinction along with some issues about the size of phonological and/or phonetic plans. I will then discuss and illustrate the dynamics of phonological and phonetic planning relative to planning at other linguistic levels and argue that phonological-phonetic planning represents the main utterance encoding processes in terms of time and costs.
