★★★★Adds schwa to plosives🇺🇸 US

Not okay when trying to teach a child!

Clemennj· 2024-10-08
★★★★Incorrect representations🇺🇸 US

As a speech pathologist, I purchased this to show my students how to produce certain sounds. Unfortunately, the animation of the tongue only represents what the middle of the tongue is doing, not the sides of the tongue. For example, for the /s/ sound, the sides of the tongue brace against the hard palate. The animation on the app, in contrast, suggests that the tongue never touches the hard palate to produce the /s/ sound.

★★★★★Not happy with it🇺🇸 US

I baught this app to usein my class. When I tried it in class full screen option did not work. I am disappointed. The website used to be free and was much more practical.

★★★★Don't buy this app🇺🇸 US

I found the website very interesting. I thought the app would be the same as the website (including the English language). This was a false propagandist. The application does not present any learning tools (it is not the same as the website). Don't buy this app. Whoever created this app stole US$3.90 (plus tax) from me!

★★★★★Not bad but…🇯🇵 JP

When watching an animation or video, the symbols for playback, 10-second forward, and 10-second reverse are constantly visible on the screen, making it difficult to view the content clearly. I strongly request improvements to address this issue.

★★★★★What happened to the website?!🇺🇸 US

I used to frequent the sounds of speech website when I was a SLP student. It was amazing and now doesn’t exist for English anymore and this app isn’t as good as the old website’s content. Why remove such a valuable resource for students and practitioners? Such a bummer

★★★★★Video quality is not good🇺🇸 US

This app used to have excellent video quality. Something has happened and now they are degraded, pixelated, and show the video controls. Please fix. Thanks. EDIT: 8/31/2021 Just following up. Is this ever going to be fixed?

★★★★★Not what is was Too Bad🇺🇸 US

I used this site in the past and purchased the app hoping it was going to be similar to the desk top version. While it offers more languages, I don’t care for the app version. Everything was on one page per sound on the desktop version. I could see both the animated and live model version. It provided a profile and head on view. So much better before. Now, I have to jump between various pages and in the process lose the students attention and just not as effective. I will use it because I paid for it but may opt for other visuals

★★★★★Great app🇺🇸 US

I love this app! I wish that there were more languages, but I use it all the time.

★★★★What happened to the German?🇺🇸 US

The original website had German. Hopefully that will be added soon

chris seidler· 2021-02-02
★★★★★The animations are misleading🇺🇸 US

The animations are misleading because the model pronounces final /p/ of “top” as aspirated when it is, in fact, unaspirated. She does this with all stops in word-final position. It’s incorrect. Moreover, there’s no modeling of the /t/ allophone [ɾ] as in “butter.”

説明が英語だけど口の動きが見れるのはよい
