About the audio
All the audio on this page comes from the American English voice of your device (text-to-speech). There are no audio files, so every word, chart card and exercise can play.
- Listen as many times as you want. Play one card, one word, or one sentence.
- See what is playing. The button that is playing turns coral with moving bars. Tap it again to stop.
- Change the speed. Use Slow to hear each sound clearly and Normal for shadowing.
- Single words. The browser voice says single words very clearly. In real speech, sounds are shorter and more connected.
- The chart is a guide. If a sound is not clear, compare the two words of the pair and follow the symbols on the page.
Works best in Chrome, Edge or Safari. The voice can be different on each device. No sound? Check the volume and the silent mode of your phone.
Start here: how to study this partAbout 60 minutes in total
Goal:By the end of this part you will tell similar vowels and consonants apart, say diphthongs, and put the strong syllable in the right place.
- Find a quiet place and use headphones. You will compare sounds that are very close, so good audio helps.
- Go in order, from the first section to the last. In each section: read, play the examples (the round play buttons), and then do the practice.
- Listen to the sound, then say it out loud. Look at your mouth in a mirror or with your phone camera if you can.
- Listen to the symbols and the examples more than once. Do not think about the spelling: think about the sound.
- Finish with the final quiz and Say it, which uses your microphone.
Tip:Two or three short sessions work better than one long one. You can repeat any activity as many times as you want, and nothing is graded.
If it does not work:No sound? Check the volume and the silent mode of your phone. No microphone? Tap Allow when the browser asks, or try Chrome.
Vowel sounds: tense or relaxed?
Spanish has five vowel sounds. American English has many more, and the letters do not always tell you the sound. The biggest difference is between tense, long vowels and relaxed, short vowels.
Tense and long
More muscle tension. You hold the sound longer.
- sheep, food, car, walk
Relaxed and short
Less tension. The sound is shorter.
- ship, foot, cut, egg

Vowel sounds in English
How to do this activityAbout 5 minutes
Goal:Train your ear to hear the difference between two similar sounds.
- Tap the audio and listen. You can listen more than once.
- Choose the word you heard.
- After you answer, play both words to compare the sounds.
- Say both words out loud. Notice what your mouth does in each one.
Tip:Tense vowels are longer and need more muscle: sheep, food. Relaxed vowels are shorter: ship, foot.
Practice 1
Listen and choose the word you hear. After you answer, play both words to compare them.
How to do this activityAbout 5 minutes
Goal:Find the word with a different vowel sound.
- Tap the audio to hear the four words, one by one.
- Listen to the vowel in each word. Ignore the spelling.
- Choose the word whose vowel sound is different.
- Play the words again and read the explanation.
Tip:Words can look alike and sound different (food, good), or look different and sound alike (blue, too).
Practice 2: odd one out
Listen to the four words. Which word has a different vowel sound?
Diphthongs: two sounds in one
A diphthong starts with one vowel sound and glides into another in the same syllable. Move your mouth: bike is not /bik/, it is /baɪk/.

Diphthongs in English
How to do this activityAbout 5 minutes
Goal:Choose the diphthong you hear.
- Tap the audio and listen to the word.
- A diphthong is two vowel sounds in one syllable. Your mouth moves while you say it.
- Choose the option with the diphthong you heard.
- Say the word out loud and feel how your mouth and tongue move.
Tip:Slide from the first sound to the second without stopping, like the sound in time or in day.
Practice 3
Listen to each word and choose its diphthong.
Consonant sounds
In English, consonants are strong and they mark the rhythm of the word. These are the sounds that need the most attention for Spanish speakers.
PROFT · REFERENCE CHART
Consonant sounds in English
At the start of a stressed syllable, they are strong, with a puff of air.
Between vowels, T and D sound like a quick, soft /d/.
In words like button, the T becomes a short stop in the throat.
B uses both lips. V uses your top teeth on your bottom lip.
Put your tongue between your teeth. θ has no voice, ð has voice.
NG ends in the back of the mouth, with no /g/. Many S letters sound like /z/.
How to do this activityAbout 5 minutes
Goal:Choose the right answer about a consonant sound.
- Read the question carefully.
- Tap the audio and listen as many times as you need.
- Choose your answer. You will see right away if it is correct.
- Read the explanation. If it was hard, go back to the section above and listen to the examples again.
Tip:Voiced sounds make your throat vibrate (like /v/, /z/, /ð/). Voiceless sounds do not (like /f/, /s/, /θ/). Put your fingers on your throat to feel it.
Practice 4
Listen and choose the correct answer.
Word stress: one strong syllable
Every English word with two or more syllables has one strong syllable: it is longer, louder and clearer. The other syllables are soft, and their vowels often reduce to /ə/.
One strong syllable
comPUter: clear and marked.
The others are soft
They reduce and lose force: cəm-PU-tər.
comPUter PHOtograph phoTOGrapher
How to do this activityAbout 5 minutes
Goal:Find the strong syllable in each word.
- Tap the audio and listen to the word.
- Listen for the syllable that is longer and louder. The other syllables are short and weak.
- Tap that syllable.
- Read the feedback, and then say the word out loud with only one strong syllable.
Tip:Every English word with two or more syllables has one strong syllable. Many two-syllable nouns are stressed on the first syllable, and many two-syllable verbs on the second.
Practice 5
Listen to each word and tap the strong syllable.
Sounds in context
One sound can change the whole meaning: ship or sheep, best or vest. Use the context to choose the right word, and then say it with the right sound.
How to do this activityAbout 8 minutes
Goal:Listen and complete the missing words.
- Tap the play button next to a line and listen. You can listen as many times as you want.
- Tap a word in the vocabulary box. You hear the word and it goes into the next empty blank. You can also type the word.
- The box has pairs of words that sound similar, and half of the words are extra. Use the meaning of the sentence to choose.
- Tap Check to see which blanks are correct. Fix the others and check again.
- Stuck? Tap Show solution and read the answers. Then tap Try again and do it without help.
Tip:If two words sound almost the same, read the whole sentence again. The context tells you which one fits.
Listen and fill in the blanks
Play each sentence and fill in the blank. The box has pairs of words that sound similar, so choose carefully. Tap a word to hear it and put it in the blank, or type it.
Vocabulary box
Minimal pairs. Tap a word to hear it. Half of the words are extra.
Prolong, stress, connect
These three habits make the biggest difference. Use them together in every sentence.
How to do this activityAbout 8 minutes
Goal:Use prolong, stress and connect together in complete sentences.
- Listen to a sentence with the marks.
- Look at the small label below it. It tells you which habit to practice in that sentence.
- Repeat the sentence out loud. Prolong the long vowels, make one syllable strong in each word, and connect the words.
- Hide the marks and say it again from memory.
Tip:Use only one habit at a time at first. When it feels natural, add the next one.
Hold the tense, long vowels: need, keep, food, car.
Make one syllable strong in each word, and one word strong in each group.
Link the words. Speak in groups, not word by word.
Listen with the marks, repeat each sentence, and then hide the marks and say it again.
