Does One ui 7.0 having different Google TTS behaviour compare with One ui 6.1?
Where can I find some documentation for developing TTS in Samsung devices?
Problem Statement
We have an application that is using Android Text To Speech(TTS) Engine from Google, everything is fine with our tester’s Samsung S23 Ultra phone which is still using Android 14 and One ui 6.1.
Recently one of our production user find that her phone is not able to populate speech with certain voice options with her Samsung S23 Ultra phone which is using Android 15 and One ui 7.0.
I do find a couple of complain in the Samsung community where it seems like the Samsung TTS is not available for third parties application anymore since One ui 7.0, but I couldn’t find notes or details regarding Google’s TTS engine.
For your information, we do having multiple phones from different brand that is using Android 15 but with different OS, which the same production application is working fine with them. Thus I want to know if One ui 7.0 or anything between 6.1 to 7.0 is having some changes that is affecting Google TTS, but I haven’t found any documentation or discussion.
Hello.
Do you mean using Google TTS or Samsung TTS?
Google TTS behavior is same for all One UI devices. However, Samsung TTS voices cannot be used in third party applications in One UI 7 devices (it worked fine in One UI 6). If you try to use Samsung TTS from third party app in One UI 7, it will fallback to Google TTS for voice.
Thanks for your reply, I meant to know about Google TTS on Samsung devices.
Production user is complaining that her Samsung S23 Ultra with Android 15 and One UI 7 is not able to use our TTS feature. After I posted the question in this forum, we manage to grab ourselves the exact same model with same android and os version, but this device that we get is able to use the application’s TTS feature.
After trying around, we do notice the issue is due to the affected device does not automatically download the Google TTS voice data when our application trying to use the feature, those device that have TTS working will automatically download the Google TTS voice data even I deleted the data manually.
So our updated question would be wanting to know what makes the different of this Google TTS engine behaviour. Does some sort of setting in Samsung device would block any sort of auto download?
