Using Espeak

Espeak is a Text-to-speech program which I have used on Ubuntu. A sample of the audio can be found from my twittergram [twittergram.com]. Note: I made a few spelling mistakes in the audio, listen and tell me if you can hear them.

espeak -f hello_jr -s 120

Interactive Text-to-Speech (Windows, Perl)

This script calls the Windows OLE for the built in TTS. Type what you want the computer to say at the prompt and hit enter. To quit type ":q" (minus the quotation marks).


use Win32::OLE qw( EVENTS );

get_text();

sub get_text{
	$output_speech = <STDIN>;
	chomp($output_speech);
	if($output_speech ne ":q"){
		say_this();
		get_text();
	}
}

sub say_this{
	my $myTTS = new Win32::OLE( "Sapi.SpVoice" ); 
	$myTTS->Speak( "$output_speech" );
	while( $myTTS->{Speaking} )
	{
		Win32::OLE->SpinMessageLoop();
		Win32::Sleep( 100 );
	}
}
