Speech! - Python Forum

Hi there!

I'm working on a simple script, and I was wondering if there is some way to use the Microsoft built-in speech SDKs (to voice, and text FROM voice)? I'd like to capture raw_input() data from my microphone whenever the program recognizes that something went through the microphone. I'd also like to have the program use the default text-to-voice synthesizer I have installed... currently Microsoft Mary.

Is this possible? If so, how might I go about doing it? Are there any simple modules with functions such as, "say()" or "listen()"? Thanks a lot!

Re: Speech!

Code: ( text )

from win32com.client import constants
import win32com.client
import pythoncom
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
self.say("Started successfully")
def say(self, phrase):
self.speaker.Speak(phrase)
class ContextEvents(win32com.client.getevents("SAPI.SpSharedRecoContext")):
def OnRecognition(self, StreamNumber, StreamPosition, RecognitionType, Result):
newResult = win32com.client.Dispatch(Result)
print "You said: ",newResult.PhraseInfo.GetText()

##### for text to speech################

Code: ( text )

Re: Speech!

Thanks for your response:

However, that is not exactly what I want. For starters, I already got the text-to-voice working. As for voice-to-text, I already tried that example, but it doesn't work how I want it to. As far as my beginner eyes can see, there's no way to replicate raw_input() using it, where if I said, "This is a test, hello world", it would enter that.

Do you understand what I'm saying? If you can show me how to use that code example, that would be great, but I just want a raw_input() style function that enters data via voice-to-text.

Thanks!
