Tools for Clear Speech

To make the /ks/ sound:
/ks/ is a consonant cluster made of two sounds, /k/ and /s/. It is often spelled with the letter “x.” Non-native speakers of English sometimes drop one of the two sounds (usually the /k/) in this cluster, which may cause the original word to sound like a different word. This cluster usually occurs following a vowel sound.

To pronounce /ks/, begin by lifting the back of your tongue and pressing it against your soft palate (the top of the back of your mouth). Push air from your throat, stopping it briefly behind your tongue, before releasing the air. As you release it, lift the tip of your tongue so it is very close to (but not completely touching) the top of your mouth, behind your teeth. Force the air between the tip of your tongue and the roof of your mouth. You should feel some resistance (friction).

In Sentences

It’s important to go beyond single words when you practice sounds in English. Tongue twisters (difficult-to-pronounce sentences) are a great way to train your tongue to pronounce /ks/ in a stream of speech.

Listen to how each tongue twister is pronounced. Be sure to note the sounds or words that might be challenging for you, and how many times you will pronounce /ks/.

Record yourself repeating each tongue twister. Try it slowly first, and then gradually increase to a fluid, natural-feeling pace.

Schedule a One-to-One Session to learn more about this sound and how to master it. Receiving direct, personalized feedback on your pronunciation is an excellent way to pinpoint your strengths and areas for improvement.
Also, here are some great ways to make pronunciation practice more effective and relevant to you:

• Compile important vocabulary with /ks/ from your field of study, résumé, and other interests. Practice these words by recording yourself pronouncing them and writing authentic sentences that use them in context.

• Think of scenarios you are likely to encounter in your daily life (e.g. talking to a fellow student or colleague, interviewing for a job) and write role plays that could include words with /ks/. This will prepare you to use them spontaneously.

• Attend Conversation Hour with the goal of focusing on your pronunciation of /ks/.

• Check out the helpful links and resources that TfCS recommends for extra practice, particularly Rachel’s English.
