is there any service for that (i saw that in Thunkable) that there is an hebrew tts
I believe your device has to have a Hebrew TTS engine installed. Thunkable does not have this built in as far as I can tell.
I found Aharon Hebrew TTS by googling.
It may work. Let us know if it works. I have no idea about the quality of this TTS engine. How does it work? I have no idea. Most TTS engines have to be installed and set using the device Settings.
As far as I know, Hebrew is not one of languages available using the Google TTS. See https://en.wikipedia.org/wiki/Google_Text-to-Speech
According to
http://ai2.appinventor.mit.edu/reference/components/media.html#TextToSpeech
that depends on the available languages on the device ...
TextToSpeech
The TextToSpeech component speaks a given text aloud. You can set the pitch and the rate of speech.
You can also set a language by supplying a language code. This changes the pronunciation of words, not the actual language spoken. For example, setting the Language to French and speaking English text will sound like someone speaking English (en) with a French accent.
You can also specify a country by supplying a Country code. This can affect the pronunciation. For example, British English (GBR) will sound different from US English (USA). Not every country code will affect every language.
The languages and countries available depend on the particular device, and can be listed with the AvailableLanguages and AvailableCountries properties.
