Art,
I kina expected you to say something. I know I've pushed this forum to its limits. for that I do not feel so well.
What type of APP? (supposed to mean application) for your Android that would you require Hal's features?
their are mixed directions and your question is not clear.
Microsoft, in some of the OS's their is a speech function.
"You have set Microsoft Sam as the computers Default voice"
also some of the Microsoft Word versions also have this feature, but they require training.
"This Papaya Tastes Perfect"
also longer readings that go beyond volume setting and adjusting the Microphone.
"The road ahead by Bill Gates" ECT
The TTS that come from Microsoft, are available to persons that have a legal copy of the correct Microsoft Product.
I hope this answers some of your questions.
Maybe someday ill find out why I had a teaching certificate from The State of Utah in my files that had Mr. Roberts name on it. And as I've stated before Their is over $90K in monies from the state that are Un-acceptable, as payment. they were in my files as well.
