3.2.10.2. 舌尖起始位置

<span class="pho">ts/dz</span> 和 <span class="pho">s/z</span> 不一样的地方在于发声时舌尖起始位置，<span class="pho">s/z</span> 舌尖起始位置贴近但没有接触到牙齿和牙龈的接缝处（位置 ②）；但，<span class="pho">ts/dz</span> 的舌尖要再往后一点，和 <span class="pho">t/d</span> 发声时舌尖起始位置一样，贴在龈脊的那个部位（位置 ③）之后开始发声。

可以用 students <span class="pho alt">ˈstudənts</span><span class="speak-word-inline" data-audio-us-male="/audios/students-us-male.mp3" data-audio-us-female="/audios/students-us-female.mp3"></span> 这个词反复体会 <span class="pho">s</span>、<span class="pho">d</span>、<span class="pho">ts</span> 的舌尖位置（注意，开头的 <span class="pho">st</span> 会被读成 <span class="pho">sd</span>）……

<span class="pho">ts</span> 和 <span class="pho">s</span> 从音质上来看就很不一样，但，<span class="pho">dz</span> 和 <span class="pho">z</span>，即便是母语使用者，也很难听出区别 —— 他们只是习惯了用不同的舌尖起始位置发声而已。
