Ratings and Reviews

Great app


Really, really great app. It really helps to pronunce well

Fabulous and accessible


Wow, this is very useful! Not only is the sound of each phoneme provided, but clear video as well. Excellent resource for higher level student of linguistics, beginners or even people trying to master articulation in their own or another language.

App is great but quiz doesn't work :(


Love the app -- the video and audio included with IPA symbols are really helpful to contrast sounds, but when I try to play the quiz, it always only shows the aspirated voiceless bilabial plosive. Even when I select it, it says I'm correct, then the next sound is still an aspirated voiceless bilabial plosive.

Also it would be great if you were able to select a group of consonants to be quizzed on so it will be easier to be able to distinguish between certain similar sounds.

Other than that, this is a great app and I highly recommend it to anyone learning about phonetics and linguistics!
