Intelligibility is the art of being understood by others. Many students think they need to speak a language flawlessly and with a native-like accent to make themselves clear, but this is not quite true.

While there is a correlation between proficiency and intelligibility, even students of lower general proficiency are capable of expressing what they mean, in a way that the listener understands, if they are using good intelligibility practices.

Being understandable in a second language is often extremely important in work environments, especially as the world becomes more connected and job markets more competitive.?

Intelligibility is a vital aspect of communication but it is not exactly a skill in itself. Instead, it is a combination of fluency, pronunciation, and managing your speed of speech. To reflect how important this is for language learners when studying, traveling or at work, we use an Intelligibility Index as part of our Versant English Test scoring.

This index is based on factors affecting how understandable speech is to fluent English speakers. These include things like speed, clarity, pronunciation and fluency. Ranging from 1 (low) to 5 (high), the Intelligibility Index shows how intelligible someone¡¯s speech in English is likely to be in a real-world situation.

Let¡¯s go into some activities and exercises you can try in class to help your students improve their intelligibility with their English and speaking skills.

How can we help our students improve their intelligibility?

There are a number of factors that influence a student¡¯s spoken English. Here are some ways to start building it into your classes.

1. Record their speech

Making a recording can be a good way of getting a clear picture of someone¡¯s current manner of speaking and understanding in what ways their clarity might be improved. You can do this using a smartphone or laptop computer in class or outside of it.

There are plenty of ways to encourage students to speak. Have them answer an open question; for example, ask them to talk for a minute about a topic they are passionate about or tell each other what they did at the weekend.

Listen to the recordings and help them analyze their speech. Identify parts with low levels of intelligibility. This may be related to their pronunciation, how fast they speak, the amount of hesitation, repetition, etc.

You could even take this further by asking another fluent English speaker to listen to the recording and give honest feedback about which parts they found difficult to understand.

Afterward, it¡¯s important to explain why it was difficult to understand and what can be done to improve their intelligibility. The activity below may help.

2. Listening and shadowing

Listening is a vital part of intelligibility. After all, students have to be able to hear a word before they can say it. Listening also takes focus away from how words are written on the page.?

This is key because speakers fluent in English tend to blend words together, so pronouncing each word perfectly in isolation is not a good goal. This kind of practice reinforces poor English pronunciation.

That¡¯s where shadowing comes in.

Shadowing is a useful listen-and-repeat activity that students can use for speaking practice almost anywhere.

  • First, select some audio for your students. It should be under five minutes in length and only be based on the speech of a single proficient English speaker. For more advanced students,??is a great starting point, have the student choose a topic they find interesting and are already familiar with.
  • Have students listen to the audio once quickly just to get used to how the speaker sounds. They should pay attention to the speaker¡¯s rhythm, accent, and speaking pace. Students should be able to understand most of what is being said.

Shadowing involves trying to say the same words as the speaker at about the same time (or as fast as possible), for about 30 seconds at a time. Students can pause, try again, and even record and listen back to their own versions. Just like when you sing the words of a song you already know well, you are trying to match the speaker¡¯s pronunciation and pace as best you can.

This will help your students focus on how fluent English speakers modulate speed, use intonation, and blend words together. By repeating what they hear, students can improve their intonation, connected speech and overall fluency.

3. Target the problem sound

This simple but fun activity will help your students focus on their individual problem sounds. It will also get them to listen to each other carefully.

Throughout the lesson, as you listen to your students speak, identify a number of words that reflect the pronunciation challenges your students face. Write the words on the board and group the words by phoneme, for example:

/i:/ Heat, Sheep
/?/ Hit, Trip

Above, we can see an issue with the /i:/ and /?/ sounds (the long and short ¡°i¡±). Once you have enough words to work on, write a list of numbers on the board. Explain that each number has a corresponding word.

1 ¨C Hit 4 ¨C Hat 7 ¨C Head

2 ¨C Heat 5 ¨C Heart 8 ¨C Hood

3 ¨C Hot 6 ¨C Hurt 9 ¨C Hid

As you can see in the above example, the words only differ by one phoneme (heat/hit, hot/hat, heart/hurt, etc.). This will make the exercise more challenging and useful for the students.

Next, identify the vowel sound in each word and write their phonemic symbols on the board.?

Drill the sounds and the words until you are confident your students can repeat them successfully. There are a number of phonemic charts online, that can help you identify the phonemes and model the sounds for your students.?

Then test the class by calling out a number and having them shout out the corresponding word. Then call out a word and get them to tell you the number. Deal with any problems that arise.

Put students into pairs. Have them read out their phone number only using the words in the list (note they can use a real number or invent one).?

Their partner should listen and write down the number which corresponds with each word they hear. They should then swap roles and do the same again.

Finally, get students to check and see whether the number their partner wrote down is correct. Monitor and go back and drill any of the sounds with which students had the most problems.

4. Transcribe and drill new vocabulary

While problems with individual sounds may occasionally impede understanding, we should also focus on other aspects of pronunciation such as word stress, sentence stress and intonation.

Keep a note of any new vocabulary that comes up during your class. At the end of the lesson, take five minutes to review it with the students. Write each new word on the board and record the word stress using the oO method:

Use ¡®o¡¯ to highlight unstressed syllables and ¡®O¡¯ to highlight stressed syllables. For example, the stress is on the second syllable of the word ¡°behavior¡±:

Be-hav-ior = oOo.

The stress is on the first syllable of the word ¡°Saturday¡±:

Sat-ur-day = Ooo

This has the advantage of recording unstressed as well as stressed syllables. Next, drill this new vocabulary until your students get the hang of it.

To make drilling more interesting, you can also add an element of drama! Have students say the words while expressing different emotions. Ask them to secretly choose an emotion (angry/happy/sad/excited), then say the word and have the other students guess it.?

You can also drill whole phrases or even sentences. Backchain drilling is an excellent way to do this and build confidence in lower-level English learners. It involves breaking phrases into sections and having students repeat them after you, from the end of the phrase to the beginning, in this way:

¡°the test¡±
¡°pass the test¡±
¡°I¡¯m going to pass the test"

As well as individual sounds and word stress, back chaining also allows you to help students with their intonation and you can also use it to introduce strong and weak forms. Working on multiword expressions and longer phrases with your students will also be helpful.

How is intelligibility scored in the Versant English Test?

Employers, schools and organizations use the?Versant English Test?to assess an individual¡¯s level of English. It covers the two skills of listening and speaking and also includes an Intelligibility Index rating alongside the GSE, Versant and CEFR scores.

This allows students, teachers and employers to see how easily others can understand the candidate.

The following list shows how the index is scored:

  • Intelligability Rating 5 -? Excellent?-?The candidate can be understood effortlessly by most listeners.
  • Intelligability Rating 4 - Good?-?Listeners may require a little effort at times to understand some of the candidate's speech.
  • Intelligability Rating 3 - Moderate?- Listeners may require some effort to understand the candidate's speech, and some may not be fully intelligible.
  • Intelligability Rating 2 - Low?- Listeners may require considerable effort to try to understand the candidate's speech. Despite the effort, it may still be mostly unintelligible.
  • Intelligability Rating 1 - Very Low?-?Listeners may find it difficult to understand most of the candidate's speech.

This scoring rubric offers a way to assess your students¡¯ intelligibility based on the method used in the Versant English Test.

By giving them lots of support and pronunciation practice and nurturing their confidence to speak without worrying too much about making mistakes, you can help them to improve their clarity over time, allowing them to communicate in clear, understandable spoken English.

    How teachers can use the GSE for professional development

    By Fajarudin Akbar
    Reading time: 4.5 minutes

    As English teachers, we¡¯re usually the ones helping others grow. We guide learners through challenges, celebrate their progress and push them to reach new heights. But what about our own growth? How do we, as educators, continue to develop and refine our practice?

    The Global Scale of English (GSE) is often seen as a tool for assessing students. However, in my experience, it can also be a powerful guide for teachers who want to become more intentional, reflective, and confident in their teaching. Here's how the GSE has helped me in my own journey as an English teacher and how it can support yours too.

    About the GSE

    The GSE is a proficiency scale developed by ÃÛÌÒapp. It measures English ability across four skills ¨C listening, speaking, reading and writing ¨C on a scale from 10 to 90. It¡¯s aligned with the CEFR but offers more detailed learning objectives, which can be incredibly useful in diverse teaching contexts.

    I first encountered the GSE while exploring ways to better personalize learning objectives in my Business English classes. As a teacher in a non-formal education setting in Indonesia, I often work with students who don¡¯t fit neatly into one CEFR level. I needed something more precise, more flexible, and more connected to real classroom practice. That¡¯s when the GSE became a turning point.

    Reflecting on our teaching practice

    The GSE helped me pause and reflect. I started reading through the learning objectives and asking myself important questions. Were my lessons really aligned with what learners at this level needed? Was I challenging them just enough or too much?

    By using the GSE as a mirror, I began to see areas where I could improve. For example, I realized that, although I was confident teaching speaking skills, I wasn¡¯t always giving enough attention to writing development. The GSE didn¡¯t judge me. It simply showed me where I could grow.

    Planning with purpose

    One of the best things about the GSE is that it brings clarity to lesson planning. Instead of guessing whether an activity is suitable for a student¡¯s level, I now check the GSE objectives. If I know a learner is at GSE 50 in speaking, I can design a role-play that matches that level of complexity. If another learner is at GSE 60, I can challenge them with more open-ended tasks.

    Planning becomes easier and more purposeful. I don¡¯t just create lessons, I design learning experiences that truly meet students where they are.

    Collaborating with other teachers

    The GSE has also become a shared language for collaboration. When I run workshops or peer mentoring sessions, I often invite teachers to explore the GSE Toolkit together. We look at learning objectives, discuss how they apply to our learners, and brainstorm ways to adapt materials.

    These sessions are not just about theory: they¡¯re energizing. Teachers leave with new ideas, renewed motivation and a clearer sense of how to bring their teaching to the next level.

    Getting started with the GSE

    If you¡¯re curious about how to start using the GSE for your own growth, here are a few simple steps:

    • Visit the GSE Teacher Toolkit and explore the learning objectives for the skills and levels you teach.
    • Choose one or two objectives that resonate with you and reflect on whether your current lessons address them.
    • Try adapting a familiar activity to better align with a specific GSE range.
    • Use the GSE when planning peer observations or professional learning communities. It gives your discussions a clear focus.

    Case study from my classroom

    I once had a private Business English student preparing for a job interview. Her speaking skills were solid ¨C around GSE 55 ¨C but her writing was more limited, probably around GSE 45. Instead of giving her the same tasks across both skills, I personalized the lesson.

    For speaking, we practiced mock interviews using complex questions. For writing, I supported her with guided sentence frames for email writing. By targeting her actual levels, not just a general CEFR level, she improved faster and felt more confident.

    That experience reminded me that when we teach with clarity, learners respond with progress.

    Challenges and solutions

    Of course, using the GSE can feel overwhelming at first. There are many descriptors, and it can take time to get familiar with the scale. My advice is to start small: focus on one skill or one level. Also, use the Toolkit as a companion, not a checklist.

    Another challenge is integrating the GSE into existing materials, and this is where technology can help. I often use AI tools like ChatGPT to adjust or rewrite tasks so they better match specific GSE levels. This saves time and makes differentiation easier.

    Teachers deserve development too

    Teaching is a lifelong journey. The GSE doesn¡¯t just support our students, it also supports us. It helps us reflect, plan, and collaborate more meaningfully. Most of all, it reminds us that our growth as teachers is just as important as the progress of our learners.

    If you¡¯re looking for a simple, practical, and inspiring way to guide your professional development, give the GSE a try. It helped me grow, and I believe it can help you too.
