Speech synthesis

Render the text “This is an example of speech synthesis.” as speech.

Speech synthesis is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

Tcl

This just passes the string into the Festival system: <lang tcl>exec festival --tts << "This is an example of speech synthesis."</lang> Alternatively, on MacOS X, you'd use the system say program: <lang tcl>exec say << "This is an example of speech synthesis."</lang> Putting these together into a helper procedure, we get: <lang tcl>proc speak {msg} {

   global tcl_platform
   if {$tcl_platform(os) eq "Darwin"} {
       exec say << $msg
   } else {
       exec festival --tts << $msg
   }

} speak "This is an example of speech synthesis."</lang>

UNIX Shell

Here we use the open source espeak tool:

Works with: Bourne Shell

Works with: bash

<lang sh>#!/bin/sh espeak "This is an example of speech synthesis." </lang>
