Chinese Pronunciation and Tone Changes Rules. Could reading given pinyin result in pronunciation errors? By Serene Zawaydeh. March 15, 2026
 

While studying Chinese, the student needs to pay attention to the tone of each Character learnt. Not only that, but there are some rules that should be implemented while reading text and while speaking. If the pinyin is given for the text, the tones shown do not always show the actual tone that should be said out loud.  

The student needs to watch out for tone changes, when coming across:
Two third tones or multiple third tones; 不; 一; and using neutral tone.

Knowing the correct tones for characters is needed to make the corresponding tone changes, and this should improve pronunciation. If the student does not pay attention to the tones while studying, as there is so much information that needs to be learnt, pronunciation will not be accurate.

Following are some examples. Details can be reviewed in multiple videos that Chinese language teachers have on Youtube. 

1) If there are two third tones, the first Character will become Second Tone.

你nǐ好hǎo，你should be second tone, since it is followed by third tone, but the pinyin will always show it as  third tone.

表biǎo演yǎn has two third tones. We will say 表biǎo as second tone, because it is followed by a third tone.

Multiple Third Tones

Chinese Zero to Hero, Topics in Chinese Linguistics, provides explanations of Tone Sandhi; how to deal with multiple third tones; and provides a sentence that is full of third tones

2) The word 不 is fourth tone.
不bù高gāo, 不bù一yí定dìng, 不bù冷lěng， 不bù忙máng
If 不is followed by fourth tone, 不 will become second tone.

Examples of 不second tone: 不bú是shì , 不bú大dà as it is followed by fourth tone.

不 would be neutral tone, when it comes in the form 忙不忙，累不累 ， 去不去。

好hǎo久jiǔ不bú见jiàn is shown correctly on MS Word.
On Google Translate, it is shown as fourth tone. This shows that different software tools sometimes make the change in tone, and sometimes do not. The student should know the rules and make the required change alone.

3) The word 一yī which means one is first tone when it is a number. If it is followed by first, second or third tone, it will be fourth tone. If it is followed by fourth tone, it will be second tone.

一yīwill be first tone when it is a number， and if it is at the end of the sentence:
一yī二èr三sān ; 第dì一yī ; 五wǔ十shí一yī

一is second tone if it is followed by fourth tone: 一yí下xià, 一yí样yàng， 一yí动dòng

一yī个gè is not correct, and when reading out loud, 一should be second tone.

一 is fourth tone, if it is followed by first, second, or third tone.  However, this change in 一’s tone will not always be shown when you use software tools, and it will be shown as first tone.

一Followed by first tone, becomes fourth tone
一yì双shuāng， 一yì心xīn： Correct. 一 is fourth tone as it is followed by first tone.

一Followed by Second Tone, becomes fourth tone

一yì直zhí， 一yì年nián  ， Correct. 一 is fourth tone as it is followed by second tone.

一 Followed by Third tone, becomes fourth tone

一yì起qǐ    ， 一yì点diǎn          Correct. 一 is fourth tone as it is followed by third tone.

The following are incorrect tones for 一

一yī只zhī，一yī棵kē， 一yī杯bēi Incorrect. 一should be fourth tone as it is followed by fourth tone.

一yī瓶píng                Incorrect. 一Should be fourth tone

一yī本běn ，一yī桶tǒng， 一yī碗wǎn, 一yī种zhǒng   Incorrect. 一 should fourth tone, as it is followed by second tone.

一yī个gè :              Incorrect. 一should be second tone, and not be first tone, since it is followed by

Notice the difference in tones that is shown if you add the tones on Microsoft Word

一yī部bù, 一yí部bù分fen,

一yī句jù， 一yí句jù话huà

It is important to know the tone of each character, as there are several characters that have a similar sound but different tones. If 一appears before each word, its tone needs to be changed according to the rules.

一yí半bàn half         一yì般bān average            第dì一yī版bǎn first edition
Notice that 上shàng班bān going to work, 班bān is first tone.

To make it easier to remember the tone changes, the key can be remembering 
不bú是shì / \ 2 4 Second if followed by fourth tone         
一yí定dìng / \ 2 4 Second if followed by fourth tone

一yì起qǐ \    fourth if followed by first, second, third tones

一 is neutral if it is mentioned in the middle of a verb that is repeated. For example 看一看， 一should be neutral tone and not first tone.

When saying phone numbers, or apartment numbers, 一 would be pronounced Yao.

Neutral Tone
The neutral tone is another point that needs to be taken into consideration, as it might not be shown precisely in software tools.

For example, if two characters are repeated, the second character would be neutral tone.
姐jiě姐jiě The second character should be neutral tone, and not third tone.

If you haven't tried adding pinyin on Mirosoft Word, it can be done using Phonetic Guide Aabc

 一个: 一 should be second tone

Here are the rules that I wrote in Chinese, to practice writing in Chinese.

朗读 或者说汉语的时候， 应该注意声调。我们不但要看一下每个汉字的声调， 而且，我们应该注意汉字的声调。 有几个规则关于声调的有变化。

比如收，我们看到两个三声的时候，我们应该说起来第一汉字用“二声，不是三声。

1.     表biǎo演yǎn， 这两个词都有是三声。 但是， 我们说出来这个词，（表）因该说出来 二声，不是三声，因为后面有三声。

下面的视频说明我们怎么能说出来一个句子，如果句子里面的词汇有有更多的三声

2.     不bù，就是四声。

但是， 如果后面有四声的汉字， 不因该改变到二声。比如说：不bú是shì。

 3.     一yī 这个词应该注意，因为有不同的规则。

如果是数字，或者是句子最后的一个词，一就是一声。比如说：第dì一yī； 五wǔ十shí一yī。

如果【一yī】 后面有四声， 我们因该改变【一】 的声调说出来二声。比如说：
一个gè。

 如果【一】后面有 一声， 二声， 三声，【一】的声调改变到四声。

我们用软件的时候，应该注意这个规则。 因为，如果我们看到拼音的时候，有的时候软件不会改变 【一】 的声调。

 比如收， 我用MS Word 的时候，我可以加上拼音用Phonetic Guide。

但是，我们看到
一yī个gè ， 一yī次cì

在谷歌翻译也不正确

在Yabla 也不是正确

这些软件都说一yī个gè，一就是一声。

但是我们应该注意，如果【一】以后有四声，【一】的声调改变到二声。

 一yí下xià    对 【一】后面有四声，【一】 的声调应该说出来二声。

 还有别的规则：
如果【一】后面的词语有一声，二声，三声的词语，【一】应该说出来四声。这个规则非常重要。如果汉语学生只看到上面写的拼音，不关注这个规则，发音有问题。

 我们来看到别的例子，看上面写的拼音对不对。

 一yì家jiā    对        【一】 的声调是四声因为后面的词语是一声。

一yī棵kē    不对    【一】以后有一声，应该改变【一】的声调到四声。

一yì年nián    对        【一】以后面有 二声，【一】 的声调应该说出来四声。

一yì直zhí    对        【一】以后面有 二声，【一】 的声调应该说出来四声。

一yì点diǎn    对        【一】后面有三声，应该改变【一】的声调到四声。

一yī本běn    不对    【一】后面有三声，应该改变【一】的声调到四声。

一yī种zhǒng   不对    【一】后面有三声，应该改变【一】的声调到四声。

The next time you see 一，make sure to look at the tone of the following character, and make the necessary change to 一's tone. In one of the past exam papers of HSKK 高级 , the text given to be read out loud had multiple 一's. 

Knowing the tones of each character is important after all.
