class TTSWSClientProtocol(WebSocketClientProtocol):

  def __init__(self):
    WebSocketClientProtocol.__init__(self)
    self.msgs = []
    self.binaryBytesReceived = 0

  def onConnect(self, response):
    logging.info('onConnect')

  def onOpen(self):
    logging.info('onOpen')
    self.sendMessage(json.dumps({'text': 'Hello <mark name="here"/> world',
                                 'accept': 'audio/ogg;codecs=opus'}))

  def onMessage(self, msg, binary):
    if binary:
      logging.info('binary message: %s bytes received', len(msg))
      self.binaryBytesReceived += len(msg)
    else:
      logging.info(msg)
      self.msgs.append(json.loads(msg))

  def onClose(self, wasClean, code, reason):
    logging.info((wasClean, code, reason))

@yashpatel001 ,
Do look into the example for speech to text using websocket here: https://github.com/watson-developer-cloud/python-sdk/blob/master/examples/speech_to_text_v1.py

@ehdsouza Thanks ,

But i want Text to speech code using websocket in python language

please help @ehdsouza

@yashpatel001,

There isn't support for text to speech using websocket in the python SDK as yet.

This is just a template: https://console.bluemix.net/docs/services/text-to-speech/websockets.html#usingWebSocket.

In the meantime you could use any websocket library to code in your example

@ehdsouza Thanks for your support.
Any release your team going to do on Websocket TTS For Android and python??
we are waiting using websocket because synthesize method is taking 2-4 second for transcript using curl and python as well as android also

How we have STT Service like that TTS Service expecting by all users in future

I submitted a Pull Request about this!
#595

[ehdsouza]

How is #595 resolving Text to speech websocket? 🤔

[D3V4N5H]

Sorry, I misread TTS as STT while I was trying to fix it. By the way I'm very happy to see the community actively participating in the development here. Let me know if I can contribute to anything in Python and Javascript.

@D3V4N5H you are more than welcome to write the WebSocket support for Text to Speech. Just make sure you write your proposal in this issue before jumping into coding so that @ehdsouza can give you some feedback. Ideally, we would have a similar interface as with Speech to Text.

Once we do it for Python we can look at https://github.com/watson-developer-cloud/node-sdk

released in #v2.5.0
