Speech synthesis

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.

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

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>
