Sandhi-voicing in dialectal Polish affects word-final obstruents in pre-sonorant and pre-vocalic environments. According to the standard descriptions, the process occurs irrespectively of the ‘underlying’ laryngeal specification of the consonant. The process has been problematic for phonological theory, with earlier accounts either requiring ad-hoc mechanisms to allow the ‘spreading’ of [voice], or providing an inadequate explanation of why the process is limited to word boundaries. In this paper, we test the hypothesis that sandhi-voicing dialects is a function of weaker word boundaries in the given dialects. Weaker boundaries go hand in hand with weaker initial syllables. We compare the speech of Standard Polish speakers (N=10) with speakers of the Poznań-Kraków dialect (N=10), who recorded sentences containing obstruent-sonorant sequences spanning word boundaries. We found acoustic evidence of weaker initial syllables for two prosodic parameters in the productions of dialect speakers. The relative strength of word-boundaries is described in the Onset Prominence model (OP; Schwartz 2010 et seq.), which also explains the role of manner of articulation in triggering the process.

This paper presents two small-scale acoustic phonetic studies investigating the pronunciation of sibilant-stop (ST) consonant clusters in Polish, and in the L2 speech of L1 Polish learners of English. In English, aspiration of fortis stops is not attested in the post-/s/ context. Rather, short-lag voice onset time (VOT) measures are observed in L1 English in post-/s/ stop consonants, a phonetic weakening that renders them phonetically similar in terms of VOT to lenis stops in initial position. In Polish, both voiced and voiceless stops may appear after sibilant fricatives. The acoustic results suggest that (1) L1 Polish does not weaken its stops in ST clusters, and (2) that more L1 Polish speakers exhibit some weakening in their L2 English clusters as a function of proficiency, but do not produce native-like VOTs in ST sequences. Implications of these findings for L2 speech research and the phonological status of ST clusters are discussed.
