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>

Clojure

Library: facts/speech-synthesis

<lang clojure>(use 'speech-synthesis.say) (say "This is an example of speech synthesis.")</lang>

GlovePIE

<lang glovepie>if var.number=0 then var.number=1 say("This is an example of speech synthesis.") endif</lang>

Go

Here's a library solution, but using a library written from scratch in Go. <lang go>package main

import ( 

   "go/build"
   "log"
   "path/filepath"

   "github.com/unixpickle/gospeech"
   "github.com/unixpickle/wav"

)

const pkgPath = "github.com/unixpickle/gospeech" const input = "This is an example of speech synthesis."

func main() { 

   p, err := build.Import(pkgPath, ".", build.FindOnly)
   if err != nil {
       log.Fatal(err)
   }
   d := filepath.Join(p.Dir, "dict/cmudict-IPA.txt")
   dict, err := gospeech.LoadDictionary(d)
   if err != nil {
       log.Fatal(err)
   }
   phonetics := dict.TranslateToIPA(input)
   synthesized := gospeech.DefaultVoice.Synthesize(phonetics)
   wav.WriteFile(synthesized, "output.wav")

}</lang>

Groovy

Mac only: <lang groovy>'say "This is an example of speech synthesis."'.execute()</lang>

Haskell

<lang haskell> import System

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

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

JavaScript

Works with: JScript

<lang javascript>var voice = new ActiveXObject("SAPI.SpVoice"); voice.speak("This is an example of speech synthesis.");</lang>

Julia

It seems that this and similar tasks can reduce to how the language can call an external program. Using the Julia REPL: <lang julia> julia> a = "hello world" "hello world"

julia> run(`espeak $a`) </lang>

Kotlin

Translation of: C
Works with: Ubuntu 16.04

Note that this code does not work on Windows 10.

Note also that Kotlin Native does not support the automatic translation of C function-like macros such as WIFEXITED and WEXITSTATUS.

Whilst it is often possible to wrap such macros in 'ordinary' C functions and then expose the latter to Kotlin via a .klib, it is not worth the effort here. I have therefore confined myself to simply reporting a non-zero error status.

<lang scala>// Kotlin Native v0.6.2

import kotlinx.cinterop.* import platform.posix.*

fun talk(s: String) { 

   val pid = fork()
   if (pid < 0) {
      perror("fork")
      exit(1)
   }
   if (pid == 0) {
      execlp("espeak", "espeak", s, null)
      perror("espeak")
      _exit(1)
   }
   memScoped {
       val status = alloc<IntVar>()
       waitpid(pid, status.ptr, 0)
       if (status.value > 0) println("Exit status was ${status.value}")
   }

}

fun main(args: Array<String>) { 

   talk("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>

M2000 Interpreter

For Linux, through wine, if missing Sapi5 need this: winetricks speechsdk


Using Statement Speech

Mathematica

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

PARI/GP

Define a function that is using espeak package from Linux. <lang parigp>speak(txt,opt="")=extern(concat(["espeak ",opt," \"",txt,"\""]));</lang>

Now let it speak: <lang parigp>speak("This is an example of speech synthesis")</lang>

A monster speech tongue-twister: <lang parigp>speak("The seething sea ceaseth and thus the seething sea sufficeth us.","-p10 -s100")</lang>

A foreign language "Zungenbrecher": <lang parigp>speak("Fischers Fritz fischt frische Fische.","-vmb/mb-de2 -s130")</lang>

Perl

<lang perl>use Speech::Synthesis;

($engine) = Speech::Synthesis->InstalledEngines(); ($voice) = Speech::Synthesis->InstalledVoices(engine => $engine);

Speech::Synthesis 

 ->new(engine => $engine, voice => $voice->{id})
 ->speak("This is an example of speech synthesis.");</lang>

Perl 6

<lang perl6>run 'espeak', 'This is an example of speech synthesis.';</lang>

PicoLisp

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

PowerShell

<lang PowerShell> Add-Type -AssemblyName System.Speech

$anna = New-Object System.Speech.Synthesis.SpeechSynthesizer

$anna.Speak("I'm sorry Dave, I'm afraid I can't do that.") $anna.Dispose() </lang>

Python

<lang Python> import pyttsx

engine = pyttsx.init() engine.say("It was all a dream.") engine.runAndWait() </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>

REXX

Works with: Windowx/XP or later

Programming note:   This REXX program uses a freeware program   NIRCMD   to interface with the Microsoft Windows speech synthesizer program   SAM,   a text to speech using a male voice.   SAM can possibly be configured to use other voices with later releases of Windows.   More recent Microsoft Windows have another speech synthesizer program:   ANNA. <lang rexx>/*REXX program uses a command line interface to invoke Windows SAM for speech synthesis.*/ parse arg t /*get the (optional) text from the C.L.*/ if t= then exit /*Nothing to say? Then exit program.*/ dquote= '"' rate= 1 /*talk: -10 (slow) to 10 (fast). */ 

                                                /* [↓]  where the rubber meets the road*/

'NIRCMD' "speak text" dquote t dquote rate /*NIRCMD invokes Microsoft's Sam voice*/ 

                                                /*stick a fork in it,  we're all done. */</lang>

Note:   The name of the above REXX program is   speak.rex
usage   using the command: 

speak This is an example of speech synthesis.

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 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")
     Central.registerEngineCentral("com.sun.speech.freetts.jsapi.FreeTTSEngineCentral")

     val synth = Central.createSynthesizer(null)
     synth.allocate()

     val desc = synth.getEngineModeDesc match {case g2: SynthesizerModeDesc => g2}

     synth.getSynthesizerProperties.setVoice(desc.getVoices.find(_.toString == VOICENAME).get)
     synth.speakPlainText(text, null)

     synth.waitEngineState(Synthesizer.QUEUE_EMPTY)
     synth.deallocate()
   }
 }

 speech( """Thinking of Holland
           |I see broad rivers
           |slowly chuntering
           |through endless lowlands,

}</lang>

Sidef

<lang ruby>func text2speech(text, lang='en') { 

   Sys.run("espeak -v #{lang} -w /dev/stdout #{text.escape} | aplay");

} text2speech("This is an example of speech synthesis.");</lang>

Swift

OS X comes with a program called "say," that does speech. <lang Swift>import Foundation

let task = NSTask() task.launchPath = "/usr/bin/say" task.arguments = ["This is an example of speech synthesis."] task.launch()</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.

<lang zx basic>10 LET s$="(th)is is an exampul of sp(ee)(ch) sin(th)esis":PAUSE 1</lang>
