MasterClass 3 β Invisible Sounds
Sounding robotic? Fix it in under a minute.
This lesson uses your device's own built-in voices. The default ones are fine, but every browser and OS also ships much more natural "premium" or "neural" voices β you just have to switch to them once.
π Mac (Safari or Chrome)
- Open System Settings β Accessibility β Spoken Content
- Click System Voice β Manage Voicesβ¦
- Under English (United States), download a Premium or Enhanced voice β try Ava (female) and Tom or Evan (male)
- Reload this page β they'll appear in the dropdowns above
πͺ Windows / any OS
- Open this lesson in Microsoft Edge β it includes very natural online neural voices by default
- In the dropdowns above, look for names with "Online (Natural)" β e.g. Aria (female) or Guy (male)
- Chrome users: look for "Google US English"
π‘ This lesson automatically tries to pick the best voice available on your device β but once you download premium voices, re-select them manually from the dropdowns to make sure they're being used.
Some sounds disappear. On purpose.
Listen to both versions below. They mean exactly the same thing β but a native speaker almost never pronounces every letter.
Every Sound
Call them tonight.
Natural Speech
Call 'em tonight.
Four Sounds That Disappear
Don't think of these as "mistakes" or "lazy speech." Treat each reduced form as its own new sound β click π to hear it inside a real sentence.
Sound 1 them β 'em (the TH goes invisible)
Sound 2 him / he / her (the H goes invisible)
Sound 3 and β 'n (the D β and often the vowel β goes invisible)
Sound 4 for β fer (the vowel shrinks to a quick schwa)
Listen & Repeat β Slow, Normal, Fast
For every sentence, press Slow first and repeat. Then Normal. Then Fast β the speed real conversation actually moves at. Say it out loud every time.
Type Exactly What You Hear
Press play β the audio is at natural, fast speed. Type what you hear, invisible sounds and all. Use "Slow replay" only if you get stuck.
Which Version Did You Hear?
Press play β the audio will randomly say either the Full Form or the Fast/Reduced Form. Choose which one you actually heard.
Decode the Reduction
Listen to the fast, natural version and pick the sentence that matches. The last two rounds combine more than one invisible sound β a real challenge!
Fluency Sprint β 30 Seconds
Pick a card. Talk for 30 seconds without stopping. Try to naturally reduce your target sound at least twice β don't force it, just let it happen the way it does in the examples.
A Real Phone Call, Full of Invisible Sounds
Listen first without reading. Only reveal the transcript once you've listened at least twice β then practice it out loud in pairs, swapping roles.
What Changed Today
- them β 'em β the TH goes invisible after a verb.
- him / he / her β 'im / 'e / 'er β the H goes invisible mid-sentence.
- and β 'n β the D (and often the vowel) goes invisible between two words.
- for β fer β the vowel shrinks to a quick, light schwa.
