Speech Sounds Visualized

I really find this app very helpful. I am a PhD student majoring in Language, Literary and Technology, and the app helps me a lot with my research. I highly recommend the app for those who are English teachers and researchers focusing on English pronunciation. Thank you to the author. 👍

I just purchased this app. I like the fluoroscopic video of the sounds being produced. However, the number of vowels depicted are insufficient (there are about 18 vowels in English if you include the 'r'-colored vowels). They completely left out the /ɔ/, as in 'caught, bought, saw, all' and substitute /ɑ/ as in 'hot', which is probably due to the dialect of the woman who is modeling the phonemes. She most likely doesn't have the vowel /ɔ/ in her personal repertoire, so it is just omitted. However, the vowels in 'cot' vs. 'caught' are separate phonemes in Standard American and RP English! I purchased the R-sound Combinations for an extra 99 cents which includes the diphthongs with the post-vocalic 'r', but what they call the Initial R is not the consonant, rather the post-vocalic 'r' as in 'word, turn, learn, girl, fern'. They left out the retroflexed liquid /r/ as in 'red'. Overall, this is a useful app, however it is deficient in its representation of the entire phonemic inventory of Standard English dialects.

My 6 year-old loves this app and uses it frequently. While using it for the first time, I noticed a marked improvement in the pronunciation of his challenging speech sounds. The combination of the visual instruction with clear audible sounds and the interactive platform all make for a great tool for children. He loves this app and so do I!
