Android Question Run TTS engine.

[John Sturt]

Hello
How do I run a TTS engine
I have the package name
and cannot find out how to run it.

Currently this is what I have

dim t as tts
dim r as reflecto
r.target = t
r.runmethod2("setpackagebyname",tts enginee name,"java.lang.string")

This does not work no errors just no result.
I am trying to rub and compile at level 21.

 

[Erel]

Do you need to change the engine?

 

[John Sturt]

Yes I have a few engines I would like to choose from.

See this thread: https://www.b4x.com/android/forum/threads/switching-tts-engines.34496/

Which error do you get?

 

[John Sturt]

I read that link before and I get no errors at all.
I am filling a listview with the package names of all
the available installed TTS engines.
After selecting one of them I push the package name through
r.runmethod2
and nothing happens.
I am running the code through a 5.0.1 nexus 5
Compiling at target level 21.

Errors I can normally deal with but getting
nothing back stumps me.
Any help?

 

[Erel]

Check the output of r.RunMethod2 when you set the engine name. It should be 0.

Wait a few seconds before you try to use TTS after you set the engine.

Please use [code]code here...[/code] tags when posting code.

It should be java.lang.String instead of java.lang.String.

 

[John Sturt]

Hello and apologies to you Erel.
Thank you that fixed the error
now I am back to the no result / error when selecting a engine.
I am going to have to have a think about this and try something else.

John.

 

[Erel]

Check the output:

Log(r.RunMethod2("SetEngineByPackageName",...)

If it not 0 then it failed to set the engine.

 

[John Sturt]

Hi Erel
The output is zero for all engines.

 

[Erel]

Are you waiting a few seconds before you call TTS.Speak?

 

[John Sturt]

Hello Erel
After the r.runmethod2 I use a wait sub to loop for a period of time.
This does not have any effect.
I use talkback to operate my devices so the TTS service is
on before I try to switch the engine.
I am trying to create a simple way to switch TTS engines , I am beginning to think about
invoking the system TTS engine menu.
