We summarized common tone problems based on speech data in the corpus. Pitch values for salient tone problems were measured using praat and plotted into tone contours.

Instead of determining learners’ tone problems relying on listening, which is abstract, teachers can refer to the concrete visualization of tone to identify learner problems and facilitate their own teaching.
