iOS Question TTS isSpeaking ?

Branko Milosevic · Jun 7, 2017

How can I inquire this variable from AVSpeechSynthesizer

B4X:

 var isSpeaking: Bool { get }

Here is link to documentation:
https://developer.apple.com/documentation/avfoundation/avspeechsynthesizer/1619680-isspeaking

I tried this but no:

B4X:

Dim no AsNativeObject = TTS1
if no.RunMethod("isSpeaking:", Null) = true then log("speaking")

You can handle the Complete event:

B4X:

TTS.Speak(...)
Wait For TTS_Complete(Text As String)
'continue here

Or:

B4X:

If no.GetField("speaking") = True Then

Cannot use TTS_Complete because the I have added UtteranceDelay which rises TTS_Complete event after every utterance in the queue.

(Line 165) no.GetField("speaking") produced this error:

B4X:

Application_Start
Application_Active

Sorry it's working, haha, somebody must have changed my code. However the
no.GetField("speaking") is a String type and I am using it as Boolean so there is a warning about that.
it's <B4i......:0> or <B4i......:1>

Change it to no.GetField("speaking").AsBoolean

Perfect. My app is done.
