Speech processing library in Python for speech to text

问题:

Hey I am looking to build a code in python which will recognise what i speak through the micrphone and convert to speech, can you please give me few effcient speech processing libraries for achieving the same??

回答1:

See pyspeech (python) - Transcribe mp3 files?

which talks about http://code.google.com/p/pyspeech/. You may also want to look at http://code.google.com/p/dragonfly/

回答2:

The dragonfly sample code misses out on a snippet while providing the code example at https://pythonhosted.org/dragonfly/

from dragonfly.all import Grammar, CompoundRule  # Voice command rule combining spoken form and recognition processing. class ExampleRule(CompoundRule):     spec = "do something computer"                  # Spoken form of command.     def _process_recognition(self, node, extras):   # Callback when command is spoken.         print "Voice command spoken."  # Create a grammar which contains and loads the command rule. grammar = Grammar("example grammar")                # Create a grammar to contain the        command rule. grammar.add_rule(ExampleRule())                     # Add the command rule to the grammar. grammar.load()                                      # Load the grammar. 

should be followed by

import time import pythoncom while True:     pythoncom.PumpWaitingMessages()     time.sleep(.1)
