few weeks ago I was able to make it finally work. Sometimes I got this error 400 but using try except in Python and repeating the request two or three times until it works was enough. Now it keeps repeating the request and every time it is the same error I get back. This is my code. Does anybody experience the same?
def stt_google_wav(audio_fname):
print "Sending ", audio_fname
#Convert to flac first
filename = audio_fname
del_flac = False
if 'flac' not in filename:
del_flac = True
print "Converting to flac"
print FLAC_CONV + filename
os.system(FLAC_CONV + ' ' + filename)
filename = filename.split('.')[0] + '.flac'
f = open(filename, 'rb')
flac_cont = f.read()
f.close()

req = urllib2.Request(GOOGLE_SPEECH_URL, data=flac_cont, headers=hrs)
print "Sending request to Google TTS"
#print "response", response
while True:
try:
p = urllib2.urlopen(req)
response = p.read()
res = eval(response)['hypotheses']
except:
print "Couldn't parse service response"
res = None
continue
break
if del_flac:
os.remove(filename) # Remove temp file
return res
