Thir Third T d Tone ne Sandhi Sandhi in Mandarin Chinese in Mandarin Chinese Thir Third T d Tone ne Sandhi Sandhi in Mandarin Chinese in Mandarin Chinese

Mandarin Chinese is a tone language which includes four basic

Mandarin Chinese is a tone language which includes four basic tones (Tone 1 to Tone 4) and a neutral one (Tone 5).

The T3 sandhi is a pronunciation rule of Mandarin Chinese, which

p , states that whenever two T3’s are in succession within the same word or the same prosodic unit, the first one must change into a tone that is indistinguishable from T2 (Xu, 1991).

For example, xi3zao3 (洗澡, “take a bath”) is pronounced as [xi2zao3].

d h bl f h f h

Here, [xi2] is indistinguishable from the pronunciation of a character

carrying a second tone such as 息 (xi2, “rest”).

Categorical view: the sandhiT3 is categorically T2

Categorical view: the sandhiT3 is categorically T2.

Gradient view: the sandhiT3 retains its phonemic identity, but its

articulation is adjusted so that it sounds similar to T2. This is akin j to a flap in pronouncing an English word latter, which sounds more like a /d/ than a /t/.

Based on the findings in the literature of no differences in f0 and

slope between the sandhiT3 and the T2, Myers and Tsay (2003) d h h dh l d b d suggested that the T3 sandhi, as is employed by Taiwan Mandarin speakers, is categorical rather than gradient.

They noted that Beijing Mandarin speakers tended to produce a

lower and flatter sandhiT3 than a T2, and accordingly suggested that the T3 sandhi in Beijing Mandarin is more gradient than that the T3 sandhi in Beijing Mandarin is more gradient than categorical.

We addressed the issue by exploiting the feedforward discrete-

stage model of word production proposed by Levelt and colleagues (Levelt, Roelof, & Meyer, 1999), as well as an experimental paradigm initially designed to test the predictions of th d l (M 1990) the model (Meyer, 1990).

Word production consists of a stage of word form encoding and a subsequent stage of actual articulation.

Word form encoding consists further of phonological encoding

Placed in this model, tone sandhi could occur during word form

RTs in the homogeneous context are faster than RTs in the

g heterogeneous context. The difference has been referred to as the implicit priming effect of the shared phonological unit (the h ll bl ) segment, the syllable, etc.).

According to the computer implementation of the LRM model, a

The advanced preparation includes retrieving the phonological contents of a word, setting up the metrical frame, assembling the segments into a phonological word, retrieving the phonetic syllables from the mental syllabary, d ibl ti ti t f th ti l t t Th and possibly activating part of the articulatory gestures. The more that can be prepared in advance, the larger the effect.

  • If tone sandhi occurs during word form encoding, target words would become

homogeneous with respect to the first tonal syllable, and a large implicit priming effect would be expected.

  • If tone sandhi occurs after word form encoding, target words would be homogeneous with

respect to the first atonal syllable, and a small effect should be the result.

The phonetic forms of T2 and T3 are quite similar. The sizable implicit

priming effect observed in Experiment 1 & 2 could be the result of p g p T2 and T3 sharing the initial portions of their tonal contours.

Studying curved hand movements, Hoffman (2010) showed that

when the goal switched after movement onset, subjects could g j adjust their movements smoothly to the new goal. Hoffman suggested that this was accomplished by ‘switching a single control d h h d l h h l command, without the need to re-plan or re-optimize the whole movement or superimpose movements’ (p. 73).

Flash and Henis (1991) demonstrated that ‘aimed arm movements

can be elicited in quick succession, without appreciable delays in responding to the target displacement, beyond the normal responding to the target displacement, beyond the normal reaction time’ (p. 220).

The results of Experiments 1 to 3 can be explained by assuming

The results of Experiments 1 to 3 can be explained by assuming that the production system prepares the first syllables of the target words in the homogeneous condition all the way after the shared g y phonetic syllable has been retrieved from the mental syllabary. The retrieved phonetic syllable is likely the one with T3. The i i h i i suspension-resumption mechanism assumes operation as soon as the system knows which target word to produce. Upon that time, the system is able to shift the articulatory gesture from that of T3 the system is able to shift the articulatory gesture from that of T3 to that of T2 if tone sandhi requires it or if the target (with an initial T2) requires it.

This articulatory account is more consistent with the gradient

view of tone sandhi.
