4 ways to improve your students' intelligibility

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
/ɪ/ Hit, Trip

Above, we can see an issue with the /i:/ and /ɪ/ 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 – Hit 4 – Hat 7 – Head

2 – Heat 5 – Heart 8 – Hood

3 – Hot 6 – Hurt 9 – 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 theVersant English Testto 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.

    4 key challenges in secondary education

    By Anna Roslaniec

    Let’s examine four of the most common challenges secondary teachers have and look into some strategies to help solve them.

    1. My students are afraid of making mistakes

    You’re not alone! Many teachers say their teenage students are quiet and unwilling to answer questions in class. Sometimes, this might simply be because they don’t know the answers, but more often than not, they are nervous about making mistakes.

    When children grow into teenagers, they tend to become more self-conscious and worried about what their peers think of them – and making mistakes in public is a big no-no for them. However, there are several ways to facilitate a safe learning environment where your students are happy and willing to talk. Sometimes, though, it takes a little experimentation. Here are some things you can try:

    Celebrate mistakes

    When students make mistakes, ensure that you praise them for taking a risk or making an effort. Correct their errors and be clear with the rest of the class that the only way to learn is to try new things.

    Be firm

    Don’t tolerate any bullying or laughing when someone gets an answer wrong. If your students fear that others will mock them for their efforts, they’ll stay quiet. So make sure you have clear rules and that your students understand that mistakes are normal and to be expected.

    Have students discuss their answers in pairs or groups

    If your students are painfully shy and afraid of making mistakes, avoid picking on individuals to answer questions in front of the class. Instead, when asking a question, tell your students to discuss it in pairs or small groups first. This will allow them to formulate their ideas and feel more confident. Afterwards, you can ask the pairs to share what they discussed – leading to a natural open-class discussion.

    Listen to your students

    Another, powerful way of engaging your students in discussion is to listen to a conversation they are having with their partners and then express how impressed you are with their ideas during a feedback session. E.g. “You said X, which I thought was very interesting. Could you explain this to the class? It was a great idea.” This gives them the confidence to share their thoughts.

    2. My students are not engaged with the activities I choose

    This is another very common problem for teachers of teenagers. You spend a lot of time thinking of fun, interesting activities – then, when you present them to the class, your students look away and say they’re bored. Soon enough, you’ll get frustrated and not know how to re-engage them. Here are some ideas to help:

    Get to know your students

    Without fail, the best way to engage your students is by getting to know them as individuals over the year. Find out about their hobbies and interests outside of school, and learn what makes them laugh and what worries them. Use your knowledge of your students to find interesting books to read, videos to watch, or relevant subjects to discuss. This way, you’ll deliver tailored lessons your students find truly interesting and useful.

    Allow a degree of autonomy

    Sometimes quietness is also a sign of disengagement with the learning materials. To get past this obstacle, you can get your students to brainstorm things that interest them in groups, list them on the board and have a class vote on the topic of their next class project. As a teacher, you always have the power to veto inappropriate ideas, but giving students a voice is a powerful way of making them feel valued and involved in their own education.

    Make things (a little) competitive

    Even teenagers love games! And play is an integral part of learning, as it allows our students to be themselves, have fun, and communicate freely at the same time. By allowing them to play language-focused games in class, they’ll soon forget their inhibitions and start talking.

    3. My students just want to do grammar exercises

    Language is all about communication, speaking, listening, reading and writing – yet all your students want to do is grammar exercises. Frustrating as this is, it’s probably a sign that our students are not confident in their speaking or listening abilities. Here’s what you can do:

    Encourage free language practice

    Grammar activities are very structured and there is often a clear answer. Day-to-day communications, however, are much freer, which can intimidate less confident students. This activity will help you combine the two aspects of language learning:

    • Put students in small groups and give them a set of cards with exciting topics printed on them—for example; music, sports, environment, school, vacations, friends, food.
    • Tell students that they should each choose a card and speak freely about their topic for 30 seconds – the short time will help them overcome their fear of speaking and can be gradually increased as they get used to this type of activity.
    • Have students record themselves when they are speaking and then, when they listen back, have them identify the grammatical structures they used.

    They should write down and correct any mistakes under your guidance. Not only will this get students used to talking and encourage a lot of emergent language, but it will also help them feel they are practicing grammar.

    If your students really enjoy learning grammar, you can ‘flip’ your grammar activities and make them more communicative. First, provide them with a series of sentences or listening clips which have a common grammatical structure (second conditional sentences, for example).

    Then have students work together (in English) to identify how the language is structured, so they can discover the grammar point for themselves. This not only gets them talking, but they are doing something they feel confident at.

    4. My students are bored of all the repetition

    Repetition is an important part of language learning. By practicing things over and over again, your students will come to understand it better and will be able to produce the language more easily. However, repetition is often quite dull, especially for fast learners. Here’s how you can make things more interesting for your teenage students:

    Use a greater variety of activities to engage your learners

    If you’ve been teaching your students a particular set of vocabulary, a grammatical structure, or some pronunciation rules, think about how else they can practice them.

    For example, instead of drilling pronunciation over and over again, ask students to think of all the words they can think of that have the same sound in them (e.g. book, look, cook, shook, etc.). This will help them ‘hear’ the sounds in their heads and improve their understanding of other words.

    If you have been learning vocabulary through reading, have students write or tell stories that incorporate the words.

    The idea is not to stop repeating the target language or skill, but to practice it in different ways. Apply this principle to other areas of language learning so your students won’t feel like they are repeating things.
