问题
I have two .wav files that I need to compare and decide if they contain the same words (same order too).
I have been searching for the best method for a while now. I can't figure out how to have pyspeech use a file as input. I've tried getting the CMU sphinx project working but I cant seem to get GStreamer to work with Python 27 let alone their project. I've messed around with DragonFly as well with no luck.
I am using Win7 64bit with Python27. Does anyone have any ideas?
Any help is greatly appreciated.

You could try PySpeech. For some more info see pyspeech (python) - Transcribe mp3 files?. I have never used this, but I believe it leverages the built in speech recognition engine of Windows. This will let you convert the Wav files to text and then you can do a text compare.
To use the Windows speech engine and use a wav file for input there are two requirements.
- Use an inproc recognizer (SpeechRecognitionEngine). Shared recognizers cannot use Wav files as input.
- On the recognizer object call SetInputToWaveFile to specify your input wav file.
You may have to resample the wav files because the speech recognition engines only support certain sample rates.
- 8 bits per sample
- single channel mono
- 22,050 samples per second
- PCM encoding
works well on Windows. See https://stackoverflow.com/a/6203533/90236 for some more info.
For some more background on the windows speech engines, you might take a look at SAPI and Windows 7 Problem and What is the difference between System.Speech.Recognition and Microsoft.Speech.Recognition?
