A phonetician is a person who studies speech sounds in a scientific way. The field is called phonetics; the phonetician is the expert who does that work. They look at how we make sounds with the lips, tongue, and breath, how those sounds travel as waves in the air, and how the ear takes them in.

A phonetician is a personPhonetician是一個人 who studies speech sounds in a scientific way用科學方法研究語音的 The field is called phonetics這個領域叫phonetics（語音學） the phonetician is the expert who does that workphonetician就是做這項工作的專家 They look at how we make sounds with the lips, tongue, and breath他們研究我們如何用嘴唇、舌頭和呼吸發出聲音 how those sounds travel as waves in the air這些聲音如何以波的形式在空氣中傳播 and以及 how the ear takes them in耳朵如何接收這些聲音

Though actually, people outside the field often use phonetician for anyone who works with speech sounds, and that is a little loose.

Though actually不過實際上 people outside the field這個領域之外的人 often use phonetician for anyone who works with speech sounds常常把phonetician這個字用在任何研究語音的人身上 and而 that is a little loose這樣用其實有點鬆散

A phonetician cares about the real, physical sound. A phonologist cares about the system a language builds with those sounds — which differences “count,” and which the language treats as the same. The two jobs sit side by side, and some people do both, but the words are not twins.
