You are encouraged to solve this task according to the task description, using any language you may know.

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

AutoHotkey

Works with: AutoHotkey_L

BBC BASIC

This calls the SAPI5 API directly, it does not need an external program. <lang bbcbasic> SPF_ASYNC = 1

C

Following shining examples of execing external programs around here:

Library: POSIX

<lang c>#include <sys/wait.h>

1. include <stdio.h>
2. include <stdlib.h>
3. include <unistd.h>

void talk(const char *s) { pid_t pid; int status;

pid = fork(); if (pid < 0) { perror("fork"); exit(1); }

if (pid == 0) { execlp("espeak", "espeak", s, (void*)0); perror("espeak"); _exit(1); }

waitpid(pid, &status, 0); if (!WIFEXITED(status) || WEXITSTATUS(status) != 0) exit(1); }

int main() { talk("This is an example of speech synthesis."); return 0; }</lang>

C#

You need to 'Add Reference' to the COM "Microsoft Speech Object Library" in your Preferences. <lang csharp>using SpeechLib;

namespace Speaking_Computer {

 public class Program
 {
   private static void Main()
   {
     var voice = new SpVoice();
     voice.Speak("This is an example of speech synthesis.");
   }
 }

}</lang>

Haskell

<lang haskell> import System

say x = system $ "espeak " ++ show x

main = say "This is an example of speech synthesis." </lang>

Liberty BASIC

Assumes that 'espeak' is available at the path shown. <lang lb> nomainwin run "C:\Program Files\eSpeak\command_line\espeak "; chr$( 34); "This is an example of speech synthesis."; chr$( 34) end

</lang>

Another dll has been posted to do the same job, at LB Community Wiki

Locomotive Basic

Both hardware and software-only speech synthesizers exist for the CPC. A software-only solution, Speech 1.1 by Superior Software (1986), supplies three BASIC extension commands (RSXes), "|say", "|speak", and "|pitch":

<lang locobasic>|say,"This is an example of speech synthesis."</lang>

Mathematica

<lang Mathematica>Speak["This is an example of speech synthesis."]</lang>

PicoLisp

<lang PicoLisp>(call 'espeak "This is an example of speech synthesis.")</lang>

Racket

Should work on all platforms. <lang racket>

1. lang racket

(require racket/lazy-require) (lazy-require [ffi/com (com-create-instance com-release com-invoke)]) (define (speak text)

 (cond [(eq? 'windows (system-type))
        (define c (com-create-instance "SAPI.SpVoice"))
        (com-invoke c "Speak" text)
        (com-release c)]
       [(ormap find-executable-path '("say" "espeak"))
        => (λ(exe) (void (system* exe text)))]
       [else (error 'speak "I'm speechless!")]))

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

Ruby

Using this module to encapsulate operating system lookup <lang ruby>module OperatingSystem

 require 'rbconfig'
 module_function
 def operating_system
   case RbConfig::CONFIG["host_os"]
   when /linux/i
     :linux
   when /cygwin|mswin|mingw|windows/i
     :windows
   when /darwin/i
     :mac
   when /solaris/i
     :solaris
   else
     nil
   end
 end
 def linux?;   operating_system == :linux;   end
 def windows?; operating_system == :windows; end
 def mac?;     operating_system == :mac;     end

end</lang>

Library: win32-utils

Works with: Ruby version 1.9

Uses espeak on Linux, say on Mac, and the win32 SAPI library on Windows. <lang ruby>load 'operating_system.rb'

def speak(text)

 if OperatingSystem.windows?
   require 'win32/sapi5'
   v = Win32::SpVoice.new
   v.Speak(text)
 elsif OperatingSystem.mac?
   IO.popen(["say"], "w") {|pipe| pipe.puts text}
 else
   # Try to run "espeak". No OperatingSystem check: "espeak" is
   # for Linux but is also an optional package for BSD.
   IO.popen(["espeak", "-stdin"], "w") {|pipe| pipe.puts text}
 end

end

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

Scala

Library: FreeTTS version 1.2

<lang scala>import java.util.Locale import javax.speech.Central import javax.speech.synthesis.{ Synthesizer, SynthesizerModeDesc }

object ScalaSpeaker extends App {

 def speech(text: String) = {
   if (!text.trim.isEmpty()) {
     val voiceName = "kevin16"

     System.setProperty("freetts.voices", "com.sun.speech.freetts.en.us.cmu_us_kal.KevinVoiceDirectory")
     try {
       Central.registerEngineCentral("com.sun.speech.freetts.jsapi.FreeTTSEngineCentral")

       val synth =
         Central.createSynthesizer(new SynthesizerModeDesc(Locale.US))
       synth.allocate()

       val desc = synth.getEngineModeDesc() match {
         case g2: SynthesizerModeDesc => g2
         case _                       => throw new ClassCastException
       }

       synth.getSynthesizerProperties()
         .setVoice(desc.getVoices().find(_.toString() == voiceName).get)
       //synth.resume()
       synth.speakPlainText(text, null)
       synth.waitEngineState(Synthesizer.QUEUE_EMPTY)
       synth.deallocate()
     } catch {
       case ex: Throwable => ex.printStackTrace()
     }
   }
 }

 speech("If it ain't Dutch, It ain't much.")

}</lang>

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> On Windows, there is a service available by COM for speech synthesis:

Library: tcom

<lang tcl>package require tcom

set msg "This is an example of speech synthesis." set voice [::tcom::ref createobject Sapi.SpVoice] $voice Speak $msg 0</lang> Putting these together into a helper procedure, we get: <lang tcl>proc speak {msg} {

   global tcl_platform
   if {$tcl_platform(platform) eq "windows"} {
       package require tcom
       set voice [::tcom::ref createobject Sapi.SpVoice]
       $voice Speak $msg 0
   } elseif {$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 bash>#!/bin/sh espeak "This is an example of speech synthesis."</lang>

VBScript

<lang vbs> Dim message, sapi message = "This is an example of speech synthesis." Set sapi = CreateObject("sapi.spvoice") sapi.Speak message </lang>

ZX Spectrum Basic

This example makes use of the Currah Speech Synthesizer peripheral device.
