Useful but omits some phonemes

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.

Useful for children with speech challenges

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!

Developer Response ,

Thank you for your review! So glad your child loves it. Speech Sounds Visualized was developed primarily for older children and adults, however some younger children enjoy recording themselves, and this helps them to improve their speech. Keep it going!

Such a fantastic idea! I’ve used this app with kiddos as a visual aid for speech sounds and adults as we discuss structures of swallow function! So glad to have this in my toolbox- highly recommend!

Thank you! So glad that you have also found it useful for work with adults who have dysphagia, or difficulty swallowing. Visuals like this can really help.
