This paper investigates the application of Shengzhou dialect tone sandhi rules in the context of sprechstimme in Shaoxing opera. Our study utilizes a corpus of Shaoxing sprechstimme, where we closely examine the tone realization of one lexical item in various contexts. Surprisingly, our findings reveal that the tone realization patterns observed in the corpus cannot be fully explained by the Shengzhou tone sandhi system. As a result, we suggest potential solutions to address the observed discrepancies.
