object has no attribute 'binary_message' - python-3.x

Question

so I'm doing a project where we use IBM Bluemix's watson to do some speech to text audio stream stuff, but I've kinda hit a wall. There's one call to a method that really messes everything up and I can't figure out why.
import pyaudio
import json
import time
import base64
import threading
import ssl
import numpy as np
from ws4py.client.threadedclient import WebSocketClient
from otherkinds import otherKinds
FORMAT = pyaudio.paInt16
CHANNELS = 1
RATE = 16000
CHUNK = 1000
RECORD_SECONDS = 20
WAVE_OUTPUT_FILENAME = "file.wav"
window = np.blackman(CHUNK)
x = 0
audio = pyaudio.PyAudio()
class SpeechToTextClient(WebSocketClient):
def __init__(self):
ws_url = "wss://stream.watsonplatform.net/speech-to-text/api/v1/recognize"
username = "a9cf87f4-7b1b-4c0a-bc7d-f4100a596a08"
password = "zBpZmqivDqAl"
authstring = "{0}:{1}".format(username, password)
base64string = base64.b64encode(authstring.encode('utf-8')).decode('utf-8')
self.listening = False
try:
WebSocketClient.__init__(self, ws_url,
headers=[("Authorization", "Basic %s" % base64string)])
self.connect()
except:
print("Failed to open WebSocket.")
def opened(self):
print("opened")
self.send('{"action": "start", "content-type": "audio/l16;rate=16000"}')
self.stream_audio_thread = threading.Thread(target=self.stream_audio)
self.stream_audio_thread.start()
def received_message(self, mensage):
message = json.loads(str(mensage))
if "state" in message:
if message["state"] == "listening":
self.listening = True
print('Listening...')
otherKinds.main_piece(str(mensage))
def stream_audio(self):
print("Waiting for Watson")
while not self.listening:
time.sleep(0.1)
print("Connected to Watson")
while self.listening:
for i in range(0, int(RATE / CHUNK * 2)):
data = stream.read(CHUNK, exception_on_overflow=False)
try:
self.send(bytearray(data), binary=True)
except ssl.SSLError:
pass
self.send('{"action": "stop"}')
time.sleep(1)
def close(self):
self.listening = False
self.stream_audio_thread.join()
WebSocketClient.close(self)
if __name__ == "__main__":
p = pyaudio.PyAudio()
stream = p.open(format=pyaudio.paInt16, channels=1, rate=RATE, input=True,
frames_per_buffer=CHUNK)
# Here is where we will merge the audio part
stt_client = SpeechToTextClient()
while (1):
pass
stream.stop_stream()
stream.close()
p.terminate()
This is the part that totally goofs everything up:
otherKinds.main_piece(str(mensage))
and this is the error message it gives me:
File "C:\Users\jared\Anaconda3\lib\threading.py", line 916, in _bootstrap_inner

I've got no idea what happening here, it works fine if I take the call out, but thats the only thing messing it up. It doesn't matter if the method is in the same file, not in a class or whatever. Any help would be great, thanks! :D
