 Posted: Tue Jun 26, 2007 11:18 am Post subject: Voice recognition |
 |
|
Your software is able to recognize a key pressure, a key sequence or a movement of the mouse. It could be nice to be able to bind action to voice orders.
"write a note"::Run notepad
or
^!"write a note"::Run notepad
Other software are already able to recognize the voice but they don't offer all the functions you able to do.
I also invite you to investigate about the GlovePIE software. GlovePIE manage more input devices like speech, joystick, joypad, wiimote, remote devices, etc... but don't offer so much output actions than you are able to do. May I hope a collaboration between those two projects is possible ? |

Speech Recognition may be possible with COM.
I found an example of how its done in Python.
| Code: | from win32com.client import constants
import win32com.client
import pythoncom
"""Sample code for using the Microsoft Speech SDK 5.1 via COM in Python.
Requires that the SDK be installed; it's a free download from
http://microsoft.com/speech
and that MakePy has been used on it (in PythonWin,
select Tools | COM MakePy Utility | Microsoft Speech Object Library 5.1).
After running this, then saying "One", "Two", "Three" or "Four" should
display "You said One" etc on the console. The recognition can be a bit
shaky at first until you've trained it (via the Speech entry in the Windows
Control Panel."""
class SpeechRecognition:
""" Initialize the speech recognition with the passed in list of words """
def __init__(self, wordsToAdd):
# For text-to-speech
self.speaker = win32com.client.Dispatch("SAPI.SpVoice")
# For speech recognition - first create a listener
self.listener = win32com.client.Dispatch("SAPI.SpSharedRecognizer")
# Then a recognition context
self.context = self.listener.CreateRecoContext()
# which has an associated grammar
self.grammar = self.context.CreateGrammar()
# Do not allow free word recognition - only command and control
# recognizing the words in the grammar only
self.grammar.DictationSetState(0)
# Create a new rule for the grammar, that is top level (so it begins
# a recognition) and dynamic (ie we can change it at runtime)
self.wordsRule = self.grammar.Rules.Add("wordsRule",
constants.SRATopLevel + constants.SRADynamic, 0)
# Clear the rule (not necessary first time, but if we're changing it
# dynamically then it's useful)
self.wordsRule.Clear()
# And go through the list of words, adding each to the rule
[ self.wordsRule.InitialState.AddWordTransition(None, word) for word in wordsToAdd ]
# Set the wordsRule to be active
self.grammar.Rules.Commit()
self.grammar.CmdSetRuleState("wordsRule", 1)
# Commit the changes to the grammar
self.grammar.Rules.Commit()
# And add an event handler that's called back when recognition occurs
self.eventHandler = ContextEvents(self.context)
# Announce we've started using speech synthesis
self.say("Started successfully")
"""Speak a word or phrase"""
def say(self, phrase):
self.speaker.Speak(phrase)
"""The callback class that handles the events raised by the speech object.
See "Automation | SpSharedRecoContext (Events)" in the MS Speech SDK
online help for documentation of the other events supported. """
class ContextEvents(win32com.client.getevents("SAPI.SpSharedRecoContext")):
"""Called when a word/phrase is successfully recognized -
ie it is found in a currently open grammar with a sufficiently high
confidence"""
def OnRecognition(self, StreamNumber, StreamPosition, RecognitionType, Result):
newResult = win32com.client.Dispatch(Result)
print "You said: ",newResult.PhraseInfo.GetText()
if __name__=='__main__':
wordsToAdd = [ "One", "Two", "Three", "Four" , "boom"]
speechReco = SpeechRecognition(wordsToAdd)
while 1:
pythoncom.PumpWaitingMessages() |
I didn't have the time to investigate how to translate it to ahk (if possible at all). Maybe someone else that has a good understanding of COM knows a little Python and has time can investigate this can make it work. Because i am busy with exploring WinSock2 with ahk at the moment.  |

Although it's outside my experience, I would like to extend AutoHotkey's input capabilities to include more types of remote controls, etc. Also, the ability to simulate joystick input (e.g. pressing of buttons) would be great because it would allow a keyboard or mouse to be used as a complete or partial substitute for a joystick.
Thanks for the suggestion. |

Just a note: Vista comes with built-in voice recognition. Works quite good  |

And the voice recognition is easy to install on XP 
More info here http://clans.gameclubcentral.com/shoot/downloads.php It's a website of shoot 1.6.4 a voice recognition software I don't use any more. The software is good but very limited.
I invite again you to investigate about the GlovePIE software. See my first message. |

Looks like foom is busy.
Anyway, here is the verbatim translation of the script foom linked.
I can't test it myself as no mike is installed on my machine.
If you hear "Starting Succeeded", then, try to say one/two/three.
NEED CoHelper.ahk.
| Code: | #Persistent
OnExit, CleanUp
CoInitialize()
pspeaker := ActiveXObject("SAPI.SpVoice")
plistener:= ActiveXObject("SAPI.SpSharedRecognizer")
pcontext := Invoke(plistener, "CreateRecoContext")
pgrammar := Invoke(pcontext, "CreateGrammar")
Invoke(pgrammar, "DictationSetState", 0)
prules := Invoke(pgrammar, "Rules")
prulec := Invoke(prules, "Add", "wordsRule", 0x1|0x20)
Invoke(prulec, "Clear")
pstate := Invoke(prulec, "InitialState")
; Add here the words to be recognized! Looks like it understands the null pointer.
Invoke(pstate, "AddWordTransition", "+" . 0, "One")
Invoke(pstate, "AddWordTransition", "+" . 0, "Two")
Invoke(pstate, "AddWordTransition", "+" . 0, "Three")
;;
Invoke(prules, "Commit")
Invoke(pgrammar, "CmdSetRuleState", "wordsRule", 1)
Invoke(prules, "Commit")
ConnectObject(pcontext, "On")
If (pspeaker && plistener && pcontext && pgrammar && prules && prulec && pstate)
Invoke(pspeaker, "Speak", "Starting Succeeded")
Else Invoke(pspeaker, "Speak", "Starting Failed")
Return
CleanUp:
Release(pstate)
Release(prulec)
Release(prules)
Release(pgrammar)
Release(pcontext)
Release(plistener)
Release(pspeaker)
CoUninitialize()
ExitApp
OnRecognition(prms, this)
{
Global pspeaker
presult := DispGetParam(prms, 3, 9)
pphrase := Invoke(presult, "PhraseInfo")
Invoke(pspeaker, "Speak", "You said " . Invoke(pphrase, "GetText"))
Release(pphrase)
}
#Include CoHelper.ahk

Sean,
The script start and I hear "Starting Suceeded". When I say "One" I hear "You said one" and a one second later I get an error message. The script crash and close.
But the most important... the voice recognition works . Thank you.

I always felt helpless when facing a situation like this where I can't test myself...
BTW, the address in the eventvwr you posted appeared somewhat odd to me.
Anyway, the one I could think of atm that can go wrong is in the following function Rec_Recognition, so I updated it.
Please recopy and try it again, and inform me about the result. |
