Unfortunately, I can't reproduce your problem on my iPhone 13 with iOS 16.5.1 in the demo app.
Is the sound of your app perhaps blocked by the "mute" switch?

@robingenz I have tested on iPhone 7 and iPhone X with IOS 16.5 speech is not being played on Loudspeakers, how can we overcome this problem? The app has taken permission, how can we debug whether it is being muted, what is the reason behind it?

here is the repo you can clone.
steps:
https://github.com/areeb-gsoftconsulting/ionic-learn/tree/text-to-speech
checkout to text-to-speech branch.
navigate to the Pages folder.
Tab1.tsx file contains our code for text-to-speech. Please try to run it on a real ios device. Speech should play on Loud Speakers. Generally, it does not play on Loudspeakers, what are the changes that we have to do to play it on Loud Speakers?

Please provide a Minimal, Reproducible Example (without unnecessary dependencies) using this template in a public GitHub repository.

Here is the new code I have created this repo that just contains code for text to speech, try to run this code. It should play speech on loudspeakers when using a real IOS device.

I tested your example, but I could not reproduce your issue. The text was read out loud.

@robingenz
Have you tested it on a Real IOS device? because it works fine, Loud on ios simulators. The problem is with Real devices.

[robingenz]

Yes, i tested it on my iPhone 13 with iOS 16.5.1.
