English speaking skills for PTE test

By: 李瑞东
16 January 2024 at 18:46

I shared my excitement about the PTE test result in the previous post. In this post, I will detail the English-speaking skills I learned during the three-month learning journey, which specifically meet the PTE test criteria.

PTE’s criteria

Let’s take a look at the two key criteria in the PTE’s speaking component: Pronunciation and Fluency.

Pronunciation and Oral fluency criteria of PTE test

Based on these criteria, I would like to highlight these key points:

Pronunciation:

  1. Vowels and consonants;
  2. Word stress;
  3. Sentence-level stress;
  4. Assimilation and deletions.

Fluency:

  1. Rhythm and phrasing;
  2. No hesitations.

As we can see, the PTE’s test criteria clearly show concepts we must fully understand and perfectly present if we want to achieve a higher score. In the following text, I will present my comprehension of these concepts, supported by related online resources.

Pronunciation

Vowels and consonants

In everyday conversations, sightly mispronounced words often do not significantly disrupt the flow of our discussion. But thanks to modern technology, PTE’s scoring is based on algorithms and is implemented by computers, which can easily detect each mispronunciation. Therefore, the ability to pronounce words clearly and accurately is crucial.

I have tried numerous methods to improve my pronunciation and reduce Chinese accent including speaking loudly, having more emotion, and directly imitating local accents. However, it didn’t work as expected, it did not meet my expectation, resulting in a low score in PTE practice.

Changes occurred the time I met Sun’s tutorials and BBC Learning English collection on YouTube. These pronunciation videos elaborate on vowel and consonant details, with vivid body language and emotion.

As non-native speakers who want to pronounce concisely, we must focus on these particular points:

Mouth Shape
We can try to imitate the mouth shape that vowels and consonants request. For example:

  1. When pronouncing /æ/ sounds like Agriculture and Activity, we should open our mouths as large as possible;
  2. When pronouncing /i:/ sounds like These and Feed, the corners of our mouths should be as far apart as possible.
Mouth Shapes of /æ/ and /i:/

Tongue Position
We should also pay attention to the tongue position. For example:

  1. The /θ/ sound requires us to extend the tongue forward;
  2. The /r/ sound requires us to pull the front part of the tongues back and up and keep the back stable, making our tongues fatter and thicker.
Tongue Position of /θ/ and /r/

Breath
We should also carefully control our breath, ensuring vowels and consonants are presented appropriately. For example:

  1. When pronouncing /θ/ like Through and Thesis, we should ensure that the airflow passes through the gap between our teeth and lips;
  2. When pronouncing /b/ and /p/ like Big and Picture, we should ensure that the airflow is completely blocked and then released suddenly.

Focusing on these points helps us ensure our study paths are on the right track, and consistently improve our pronunciation. In addition, there are two tips:

  1. Don’t try to imitate accents. The PTE test does not expect you to have a perfect British or American accent. For beginners, attempting to achieve such an accent is time-consuming and pointless.
  2. Never compare pronunciations between English and Chinese. For instance, the Cantonese pronunciation 士多啤梨 is often equated with Strawberry in English, which overlooks many nuances. Therefore, it is important to acknowledge that the pronunciation of English and Chinese words are completely different.

Online Resources:

Word stress

Each Chinese character has only one syllable, whereas English words typically consist of two or more syllables.

For example, the word water consists of two syllables: wa-ter, and phenomenon consists of five syllables: phe-nom-e-non. It depends on how many vowel sounds the word includes.

Syllable numbers of the word “the”, “water” and “phenomenon”

Furthermore, an English word consisting of two or more syllables includes both stressed syllables and unstressed syllables. These are indicated by the phonetic symbols found in dictionaries.

For example, the phonetic symbol of agri-cul-ture is /ˈæɡrɪ-kʌl-tʃər/, we can see the stress mark /'/ is placed in the first syllable /ˈæɡrɪ/, which known as a stressed syllable, while others are unstressed syllables.

Stressed syllable and unstressed syllables of the word “agriculture”;

An interesting rule to note is that the stressed syllable can be vary within the same word depending on its function in a sentence. For example:

  • When Project is acting as a noun, it is pronounced: /ˈprɑːdʒekt/
  • When Project is acting as a verb, it is pronounced: /prəˈdʒekt/

What should we do?
Pronounce each syllable with different efforts:

  1. Stressed syllables should be pronounced longer and louder;
  2. Unstressed syllables should be pronounced shorter and thinner, or take place from the Schwa (we will discuss it later.)

When training pronunciation, I strongly recommend exaggerating these nuances to ensure we are on the right track and fully comprehend this concept. Eventually, it should sound natural and require less effort.

Properly presenting word stress is key to making our speech more like English, and it can significantly help in shedding “Chinglish” tendencies.

Online Resources:

Sentence-level stress

To meet this criteria, there are two concepts we should understand: Content/Grammar Words and Stressed Words.

In the English world, there are two types of words within a sentence: Content words and Grammar words.

  1. Content words like nouns, verbs, adjectives, and adverbs play an important role in sentence structure and convey main information.
  2. Grammar words like prepositions, auxiliary verbs, and articles are used to link content words to make a complete sentence, we can’t understand a sentence that only includes grammar words.
In the sentence “I would like to read books,” the content words are “I”, “like” “read” and “books”; while the grammar words are “would” and “to.”

In the sentence “I would like to read books,” the content words are I, like, read and books, they should be pronounced clearly and accurately, while would and to are grammar words, and they should be pronounced more softly than those content words.

The second point is to decide which words should be stressed. This is an easy-to-understand concept but hard to implement when we are facing a complex sentence. I will demonstrate it through Chinese examples:

Two examples of stressed word.

We stress some special words in our mother tongue subconsciously, furthermore, and this often influence the meaning.

For instance, we can express “There are beautiful flowers in the park.” in these different ways:

  1. There are beautiful flowers in the park.” We are pointing out the location;
  2. “There are beautiful flowers in the park.” We are emphasizing the flowers, not buildings or trees;
  3. “There are beautiful flowers in the park.” We are emphasizing the place where the beautiful flowers are located.

I suggest following general rules to avoid the potential risk of making mistakes and mispronunciation because the given text is unpredictable when we are sitting at the PTE test. Here are two steps for consideration:

1. Understanding the text.
Rather than speaking without consideration and comprehension, we should first grasp what ideas the writer attempting to convey before we open our mouths. Furthermore, analyzing the elements and structure of the sentence is crucial, including subjects, verbs, objects, content words, grammar words, and clauses.

2. Marking stressed words and unstressed words.
Generally, we stress one word in a phrase, choosing from a range of words, including objects, gerunds, passive verbs, adjectives, and adverbs. Below are several examples from an actual test:

Globalisation refers to a set of changes rather than a single change.
In the sentence “Globalisation refers to a set of changes rather than a single change,” the stressed words are “set” and “single.”

Stress what authors attempt to emphasize. In this case, the author is declaring it is a set, not a single change.

You will be introduced briefly to the discipline of child psychology.
In the sentence “You will be introduced briefly to the discipline of child psychology,” the stressed words are “introduced,” “discipline,” and “child.”

We always stress adjectives and adverbs that modify a noun. If they are connected, stress the first one. Similarly, when facing a compound noun, we stress the first noun generally.

Although choosing the stressed words is subjective, they should be chosen from an appropriate scope that I mentioned before.

Online Resources:

Assimilation and deletions

These two concepts were the most interesting part of my learning journey. They make our English speaking vivid and dynamic.

Some voices can be transformed in specific circumstances. Below are several examples:

  1. Using the Schwa. Grammar words and articles can be reduced to a “Schwa sound”, such as “to” /tu/ becoming /tə/, and "than" /ðæn/ becoming /ðən/;
  2. Linking vowels. When a word ends with explosive sounds like /t/, /k/, and /p/ and the following word begins with a vowel sound, we link them together, such as that element becoming tha-telement;
  3. Inserting new sounds. When a word ends with a vowel sound and the following word begins with a vowel sound, we often insert a connecting sound. For instance: many of can be many jof.

There are lots of variations in pronunciation that we need to learn and practice. While this might feel overwhelming for some beginners, it is a vital part of speaking like a native and sounding natural. Keep learning from online resources and practice consistently until you feel comfortable.

Some voices can be dropped in specific circumstances. Below are several examples:

  1. Combining sounds. Link the same consonant sounds that are adjacent, such as in big garden, two /g/ sounds becoming one /g:/ sound but a bit longer;
  2. Dropping sounds. In a rapid speech, we sometimes drop explosive sounds between two consonants, such as an important role becomes an importan role;
  3. Holding sounds. Similarly, we hold back explosive sounds without fully releasing them when these sounds between a vowel and a consonant, such as that person becomes tha-person;
  4. Reducing /h/ sounds. When a word ends with explosive sounds and the following word begins with the /h/ sound, we always reduce the /h/ sound, such as "might have" becomes "migh-t(h)ave" and "an hour" becomes "a-nour."

Online Resources:

Fluency

Rhythm and phrasing

These two concepts are related to the term “Thought groups.” When speaking English, we always separate the sentences into several groups by their meanings, emotions, structures or lengths. Here is an example from the real test:

Two examples of separating sentences.
  1. Many papers you write in college / will require you to include quotes / from one or more sources.
  2. The speaker reminisces about his views / of the English Revolution / when he was a student.

In particular, we break sentences down before prepositions such as “of”, “in” and “that.” Importantly, we should NEVER separate compound words like “the English Revolution.”

Furthermore, I suggest breaking the sentence into smaller fragments for practice, like this:

An example of using high pitch and low pitch.
Many papers / you write in college / will require you / to include quotes / from one or more sources.

However, the PTE test would perfer a longer phrase, so I suggest that each group should have 4 to 7 words.

Now we know what is the term “Thought groups” and how to divide a sentence, the next step is to learn how to present it well. This related to the term ‘intonation and it means words pronounced in a high or low pitch accordingly and intermittently.

Intonation can bring rhythm to speaking, however, it is hard to handle and can cause trouble easily for beginners.

An example of using high pitch and low pitch.

What should we do?

  1. Always present a low pitch to the last word of a thought group and the sentence;
  2. Carefully present a slightly high pitch to the adjectives or adverbs that modify a noun or a noun phrase.

No hesitations

PTE test can detect any hesitation or mispronunciation which can negatively influence our final score, especially in the Read Aloud and Repeat Sentence module.

Despite numerous challenges on test day, such as being disrupted by other test-takers or encountering unfamiliar words, I strongly recommend speaking slowly and confidently to avoid potential risks and maintain fluency.

This strategy is crucial: when we face a word or phrase that is difficult to express and may cause hesitations unavoidably, this may affect our scores in both Pronunciation and Fluency. However, if we express these challenging words slowly and confidently, maintaining a natural flow, it might primarily affect our Pronunciation score.

This is why I strongly advocate for speaking confidently, even when making mistakes.

Summary

This article discusses the knowledge I gained on my English learning journey, including methods to improve pronunciation and an understanding of the PTE speaking module criteria.

Additionally, I’ve decided to update posts in English from now on. It may contain numerous grammatical errors, awkward phrasing and word-choice issues, it’s still a necessary step forward. ‘Practice makes perfect’ is the key lesson from this journey.

App 表单校验时机探索

By: 李瑞东
17 August 2022 at 14:14

动机

在我接手 App 这波需求迭代的时候,发现一个很常见的问题却没有在设计规范里提到过(其实原本也没啥设计规范…)。那就是:表单的校验时机。

工作中我发现每个保存到数据库的表单都会有至少一个校验规则,最常见的是字数,其他的有类似格式(邮箱、数量)、上下限(价格、库存数)等。而表单的校验时机通常是在三种方式内选择:

  1. 输入中校验;
  2. 失焦后校验;
  3. 提交时校验。

由于接手时并没有规范或者指引帮助我如何判断使用哪种,工期紧张也没有足够时间去探索,我只能拍脑袋地大部分都采取了「失焦后校验」的方法。

后面我发现这其中的差异还是挺耐人寻味的,有必要探索三者之间的各自优劣势和适用场景,于是乎就有了这篇文章。

三种校验时机的差异

输入中校验

效果:输入过程中(即文本有更改时)校验并反馈报错文案。
优点:实时反馈,出错后立即提示。
缺点:容易误判。即未完成输入就提示出错。

适用场景:
1. 纯前端能满足校验需求时;
2. 校验规则较严苛时,如一个表单多条校验规则,或中途某个错误字符直接影响到表单提交时。

修正错误的成本:低
在手机的的「键盘控件」内重新键入内容即可完成修正。

失焦后校验

效果:失去焦点后校验并反馈报错文案。
优点:输入过程中无干扰,在输入完成后再反馈报错文案。
缺点:失焦后才知道结果,修正成本高。

适用场景:
1. 纯前端能满足校验需求时;
2. 用户对输入框内容格式有预期时,如邮箱、手机号等。

修正错误的成本:高 ★★
需要先「失焦」,再回到原本的输入框「重新聚焦」,并通过「键盘控件」修正。

提交时检验

效果:提交表单时校验并反馈报错文案,通常会伴随着使用 Toast 提示。
优点:后端校验时,不影响性能&体验。
缺点:报错反馈很不及时。

适用场景:
1. 大部分需要后端校验的表单。

修正错误的成本:较高 ★★★
需要先「提交表单」,再「找到」出错的的输入框,并「重新聚焦」原本的输入框,通过「键盘控件」修正。

至此,上面列出了三种校验方式的各自优劣势,对比后不难得出结论。

结论

推荐优先使用「输入中校验」的规则。

原因:
1. 反馈最及时;
2. 修正错误的成本最低;
3. 对研发工作量和 App 性能无影响(前端校验时)。

理论支撑:

“理想情况下,所有验证都应该是内联的…”
“…在字段完成后立即修复错误对用户的交互成本最低…”
—— 来自 Nielsen Norman Group 的《如何反馈表单中的错误:10 条设计指南

通过这次的对比,我决定了之后都将「输入中校验」作为主要的校验方式,当然这种方式也有一些不适用的场景,此时就需要换一种校验方式。举例一些常见的不适合用「输入中校验」的表单:

  1. 容易误判的表单,如校验邮箱、电话、网址的格式时;
  2. 设置了数量下限时,如公司业务里的 B2B 商品设置了起批量时;
  3. 需要后端校验时,如需查重或对比数量上下限时。

其他感悟

对需要后端检验的表单态度

因为涉及到后端检验,意味着需要网络,那就会出现加载中/超时/加载失败/加载成功 的情况,所以这种表单一般是失焦后或提交时检验,这对输入体验会相对友好一些。

但也有例外,比如 Twitter 账号在重命名时,就使用的是输入中校验。可能是因为 Twitter 用户量庞大,特别容易重名。提交后检验反而效率更低。

输入前的体验设计

常言道好的体验设计能减少用户出错,在表单输入之前,实际上我们也可以用多种方式明示暗示文本框的填写规则。

一、输入框长度

输入框长度能过暗示文本框的预期填入内容。比如在填地址和邮编时,通常地址我们会预留比较宽的输入框给用户填写,而邮编则可以相应缩减,因为这两个类型的字段,预期填写的文本长度是有明显不同的。

二、实时字数显示

在输入框旁边实时展示当前字数和上限是也是比较常见的做法。
优点:避免出错;让用户对表单的规则有一个预期。
缺点:页面出现过多此类提示会使页面臃肿,反而会增加视觉&认知负荷。

所以我对这个做法的态度是:每个表单都会有文字输入的上限,超过上限时也一定会禁止提交、出现提示。但是否将字数提示常驻展示,取决于「用户对长度是否有预期」。

比如在一些备注、描述、说明等大段文字里,用户可能会输入到大段文本,但又对这些输入框的上限没有预期,那我这里判断到是需要出现实时字数提示的。而像比如填写姓名、添加标签这种,字数上限只是一个兜底的判断逻辑,不需要特意暴露出来。

另外可以根据存量数据来决定是否展示实时字数提示。比如让后端同事帮忙导出在数据库里的数据,能知道用户在这个输入框里一般会填写多少个字,如果大部分情况都是接近字数上限的,意味着用户在这个输入框会输入较多的文本,此时就需要展示当前字数上限,甚至或者调整校验规则。这是我在上一家公司(千聊)里做过的事情。

三、占位符(Placeholder)

无论是 NNGROUP 还是 Shopify UX,都对占位符文本持有比较谨慎的态度,甚至会用到 Harmful、Avoid 等贬义词。他们主要批判的是用占位符代替标签的做法,我们在使用时避免这种用法就好了。

实际上占位符和标签共同使用时没什么毛病,占位符确实能起到一定的补充作用,用来提示要输入内容的类型和名称,只是不要用来展示重要内容和代替掉标签就好了。合理使用也是减少用户出错的方式之一。

四、常驻帮助文本(Help text)

帮助文本可以视为占位符的进阶版,具体效果在输入框附近常驻一段简短、必要的说明内容,帮助商家了解输入框所要求的格式,或输入后的内容会怎么处理。甚至还可以链接到 FAQ,有丰富的用法。

一条原则

在文本有上限的输入框里,我们会面临一个选择是:超过字数后是否允许输入?

我在这里的建议是允许继续输入,同时会出现报错的反馈,告知规则。因为翻查了很多 UX 资料,都建议在设计中要避免「打断了用户行为」。下面放出两种方法的优劣对比,各位看官理性抉择:

超上限后允许继续输入
效果:输入的文本超过该文本框校验规则上限时,出现报错反馈,同时也可以继续输入文本。
优点:反馈及时,原因清晰。
缺点:🤔…

到达上限后禁止输入
效果:输入的文本到达该文本框校验规则的上限时,禁止输入更多的文字了。
优点:🤔…
缺点:没有反馈,不知道错误原因。

这么看下来,就体验而言是「超出上限后允许继续输入」要好很多。而且这种方法还照顾到一个场景是:允许用户在输入中发现超出长度后,把当前的单词输入完整后再去删减其他内容。

当然毫无疑问,到达上限后直接不允许输入是对设计和研发来说最省力的做法。这种做法下不用反馈,也就不需要做反馈时机的决策、反馈的文案及多语言、文本的适配、反馈后的布局适配…

我有一段经历是项目工期巨紧张,规范也没相关的指引。当时有很多比制定文本输入规则还重要的事情需要处理,于是乎我就都一拍脑袋用了「达上限后禁止输入」的方法。

后面与其他方式对比发现这种做法应该是体验比较差的做法了。像现在我把规范做法加进 App 设计的指引里面之后,就大多数情况下都会使用「允许继续输入,在输入中反馈」的方式实现。

结语

以上内容就是目前来说我对文本框校验规则的一些认识,包含了各种校验时机的对比,输入前的体验设计,以及不打断用户操作的原则。

这次的总结是我挺久之前就想干的事情了,因为平常工作中一直遇到这种问题,也没有一个明确的设计指引能够参考,现在自己写下来这篇笔记之后,之后的设计方案会考虑得更周全,说服力也更强了(希望是吧)…

同时再浅挖一个坑:之后要探索下表单提交按钮相关知识,比如说什么时候要禁用按钮,什么时候是允许点击但报错等等,这个应该还要复杂一点…
