how to use windows default voice using java? [duplicate]

Is there a way to use the MS Speech utility from command line? I can do it on a mac, but can't find any reference to it on Windows XP.

My 2 cents on the topic, command line one-liners:
on Win using PowerShell.exe
PowerShell -Command "Add-Type –AssemblyName System.Speech; (New-Object System.Speech.Synthesis.SpeechSynthesizer).Speak('hello');"
on Win using mshta.exe
mshta vbscript:Execute("CreateObject(""SAPI.SpVoice"").Speak(""Hello"")(window.close)")
on OSX using say
say "hello"
Ubuntu Desktop (>=2015) using native spd-say
spd-say "hello"
on any other Linux
refer to How to text-to-speech output using command-line?
commandline function using google TTS (wget to mp3->mplayer)
command using google with mplayer directly:
/usr/bin/mplayer -ao alsa -really-quiet -noconsolecontrols "http://translate.google.com/translate_tts?ie=UTF-8&client=tw-ob&q=Hello%20World&tl=en";
on Raspberry Pi, Win, OSX (or any remote) using Node-Red
npm i node-red-contrib-sysmessage

There's a nice open source program that does what you're asking for on Windows called Peter's Text to Speech available here: http://jampal.sourceforge.net/ptts.html
It contains a binary called ptts.exe that will speak text from standard input, so you can run it like this:
echo hello there | ptts.exe
Alternatively, you could use the following three line VBS script to get similar basic TTS:
'say.vbs
set s = CreateObject("SAPI.SpVoice")
s.Speak Wscript.Arguments(0), 3
s.WaitUntilDone(1000)
And you could invoke that from the command line like this:
cscript say.vbs "hello there"
If you go the script route, you'll probably want to find some more extensive code examples with a variable timeout and error handling.
Hope it helps.

There's also Balabolka: http://www.cross-plus-a.com/bconsole.htm
It has a command line tool balcon.exe. You can use it like this:
List voices:
balcon.exe -l
Speak file:
balcon.exe -n "IVONA 2 Jennifer" -f file.txt
Speak from the command-line:
balcon.exe -n "IVONA 2 Jennifer" -t "hello there"
More command line options are available. I tried it on Ubuntu with SAPI5 installed in Wine. It works just fine.

If you can't find a command you can always wrap the System.Speech.Synthesis.SpeechSynthesizer from .Net 3.0 (Don't forget to reference "System.Speech")
using System.Speech.Synthesis;
namespace Talk
{
class Program
{
static void Main(string[] args)
{
using (var ss = new SpeechSynthesizer())
foreach (var toSay in args)
ss.Speak(toSay);
}
}
}

There is a powershell way also:
Create a file called speak.ps1
param([string]$inputText)
Add-Type –AssemblyName System.Speech
$synth = New-Object System.Speech.Synthesis.SpeechSynthesizer
$synth.Speak($inputText);
Then you can call it
.\speak.ps1 "I'm sorry Dave, I'm afraid I can't do that"

rem The user decides what to convert here
:input
cls
echo Type in what you want the computer to say and then press the enter key.
echo.
set /p text=
rem Making the temp file
:num
set num=%random%
if exist temp%num%.vbs goto num
echo ' > "temp%num%.vbs"
echo set speech = Wscript.CreateObject("SAPI.spVoice") >> "temp%num%.vbs"
echo speech.speak "%text%" >> "temp%num%.vbs"
start temp%num%.vbs
pause
del temp%num%.vbs
goto input
pause

Your best approach is to write a small command line utility that will do it for you. It would not be a lot of work - just read text in and then use the ms tts library.
Another alternative is to use Cepstral. It comes with a nice command line utility and sounds light years better than the ms tts.

Runtime.getRuntime().exec() issue

I'm trying to run another programm from Java code:
String[] command = {"gdal_polygonize.py", "/home/user/myoldfiles/proceeded.tiff", "-mask", "/home/user/myoldfiles/biomass_02.08.14.tif", "-f", "'ESRI Shapefile'", "/home/user/myoldfiles/proceeded.shp", "DN"};
Process p = Runtime.getRuntime().exec(command);
I have no file proceeded.shp created in /home/user/myoldfiles/
The command output obtained with BufferedReader looks like:
Creating output /home/user/myoldfiles/proceeded.shp of format 'ESRI Shapefile'.
When I run next command in terminal(Ubuntu)
gdal_polygonize.py '/home/user/myoldfiles/proceeded.tiff' -mask '/home/user/myoldfiles/biomass_02.08.14.tif' -f 'ESRI Shapefile' '/home/user/myoldfiles/proceeded.shp'
It prints
Creating output /home/user/myoldfiles/proceeded.shp of format ESRI Shapefile.
0...10...20...30...40...50...60...70...80...90...100 - done.
And successfully creates proceeded.shp file. What am I doing wrong in Java code?

Thanks everybody for the help! I found solution here. The problem was in single quotes in 'ESRI Shapefile', I just deleted them and all works fine now!

Different output -- when running mathtext in command line and when the command is executed from a java program using apache-commons-exec

I am trying to run mathtext from a java program using apache-commons-exec. The problem is I am getting different output when I run the same command from a java program and when I run it through shell.
so if run mathtext like this in the shell:
./mathtext test.png "\$\frac{{\left( {{p^2} - {q^2}} \right)}}{2}\$"
in a shell I get the perfect png
but when I run the same thing using apache-commons-exec
Map map = new HashMap();
map.put("target", new File(trgtFileName));
DefaultExecuteResultHandler resultHandler = new DefaultExecuteResultHandler();
Executor exec = new DefaultExecutor();
exec.setWorkingDirectory(/*I set the working directory where the mathtext is*/);
CommandLine cl = new CommandLine("./mathtext");
cl.addArgument("${target}");
cl.addArgument(latex);
cl.setSubstitutionMap(map);
// Logger.log4j.info("command is:::"+cl.toString());
ExecuteWatchdog watchdog = new ExecuteWatchdog(5000);
exec.setWatchdog(watchdog);
exec.execute(cl,EnvironmentUtils.getProcEnvironment(),resultHandler);
resultHandler.waitFor();
I get the image, not the equation but the raw TeX string :(
Can somebody please help me in solving the issue? I want to get the exact output.
Thanks.

I figured out where the problem was:
$ is a special character for the unix shell and not for java. So even if in the command line the input needs to escape $ like:
"\$\frac{{\left( {{p^2} - {q^2}} \right)}}{2}\$"
inside the java program I dont need to escape the '$' or put " (double quotes) at the beginning and at the end.I had to put the command like:
$\frac{{\left( {{p^2} - {q^2}} \right)}}{2}$
Hope this helps somebody :)

how to run cygwin script from java

I'm trying to run a bash script from a Java program I'm writing in windows. I've been trying to use the Runtime object to get a process to work, and my program compiles and runs without exceptions, but my simple test script, which just makes a directory, is not being executed.
Here's what I've got so far:
String cmmd[] = new String[3];
cmmd[0] = "C:\\cygwin\\bin\\bash.exe";
cmmd[1] = "cd C:/Users/pro-services/Desktop/projects/github/cygwin";
cmmd[2] = "bash TEST.sh";
Runtime rt= Runtime.getRuntime();
Process proc = rt.exec(cmmd);
This is basically a mix of different things I've found in forums around the net, but I guess I just don't really understand what is happening with the Process class (and I only have a basic idea about the Runtime class).
I also found this, and plugged my own stuff in where I thought it should go:
Runtime.getRuntime().exec(new String[]{"C:\\cygwin\\bin\\bash.exe",
"-c", "c:\\cygwin\\bin\\run.exe -p /bin bash C:\\Users\\pro-services\\Desktop\\projects\\github\\cygwin\\TEST.sh"},
new String[]{"PATH=/cygdrive/c/cygwin/bin"});
Here I'm not sure what the "-c" and "-p" strings represent, but I just went with it. At first it looked like I could just plug in the sequential commands that I want the Runtime/Process object to execute, in essence creating a "script" to run my script. But it now seems that there's more to it...
I'm just shooting in the dark at this point, and I have tried to understand the documentation but I'm lost. Any help would be appreciated. Thanks )))

Untested, but I would think:
cmmd[0] = "C:/cygwin/bin/bash.exe";
cmmd[1] = "-c";
cmmd[2] = "cd /cygdrive/c/Users/pro-services/Desktop/projects/github/cygwin && bash TEST.sh";

Adding parameters to Runtime.getRuntime()?

void restartWeb() {
try {
String[] command = new String[] {"webRestarter.exe" , ">>","webLog.log"};
Runtime.getRuntime().exec(command);
} catch (java.io.IOException err) {
webServer.logError(err.getMessage());
}
}
Why doesn't this work? How could I fix it so it does work like I want it to?
-- Executes webRestarter.exe with parameters >>webLog.log
So it'd spit out something like this:
webRestarter.exe>>webLog.log

You simply can't use pipes in a exec call. Pipes are a functionality of the shell and not of the operating system. So we have to call the shell executable and pass the command. Try this instead:
String[] command = new String[] {"cmd.exe", "/c", "start webRestarter.exe", ">>","webLog.log"};

Parameters are passed directly to the webRestarter.exe command. You can't use parameters to redirect standard output to a file, as this is usually done by your command line interpreter.
However, the exec() method returns a Process object, which you could use to retrieve standard output and write it to a file.

If I'm not mistaken, pipes, redirects etc are a function of a shell. In this context, these are just arguments. You could handle this as simply as using cmd.exe with a /c switch as part of your command, I believe it'll handle this correctly, or handle the standard input/output yourself (though that's notoriously fraught with problems, I prefer something like commons-exec).

Just thought I'd mention two things that might be handy for working with Processes.
ProcessBuilder
is a good way to obtain a Process (in
code intended to run in a 1.5+ JRE).
It is recommended to carefully
read and implement all the
recommendations of When
Runtime.exec() won't.
