Text to speech doesn't work and no errors showed.

Hi. No any sound made from bot when it responds.

I am testing bot on localhost with botEmulator.
OS: Linux Ubuntu
"name": "botframework-emulator",
"version": "3.5.35",

Used valid MS App ID and MS APP password in BotEmulator and Bot app.

Bot code:

bot.dialog(intents.Greeting, function (session) {
  const userName = session.message.user.name;
  var msg = new builder.Message(session)
    .speak('This is the text that will be spoken.')
    .inputHint(builder.InputHint.acceptingInput);
  session.send(msg).endDialog();
})
  .triggerAction({
    matches: intents.Greeting
});

Bot responds on greeting.. and response JSON is:

{
  "type": "message",
  "speak": "This is the text that will be spoken.",
  "inputHint": "acceptingInput",
  "locale": "en-US",
  "localTimestamp": "2018-06-07T14:17:34+03:00",
  "from": {
    "id": "default-bot",
    "name": "Bot"
  },
  "recipient": {
    "id": "default-user"
  },
  "id": "someID",
  "replyToId": "someID",
  "channelId": "emulator",
  "timestamp": "2018-06-07T11:17:34.570Z",
  "conversation": {
    "id": "someotherID"
  }
}

No any errors in logs. Just this:

[14:11:18] Emulator listening on http://[::]:44979 
[14:11:18] ngrok not configured (only needed when connecting to remotely hosted bots) 
[14:11:18] Connecting to bots hosted remotely

[14:17:31] -> POST 202 [conversationUpdate] 
[14:17:31] -> POST 202 [conversationUpdate] 
[14:17:33] -> POST 202 [message] hello 
[14:17:34] <- POST 200 Reply[message] 
[14:17:34] <- POST 200 Reply[event] Debug Event  `

I've read all issues cases on Git, but still cannot hear any sound from the bot.
Will be greatfull for help.Maybe I do something wrong but it's hard to see from my side:)

@meksikann sorry for the delay, can you confirm which version of Ubuntu are you using?

@meksikann Sorry for the delay in getting back to you.
Bing Speech underwent a big API update to Speech Services back at this year's Ignite. Because of this, Bing Speech no longer allows the creation of new speech bots, and Bing Speech will be deprecated in 10/2019.

Our plan is to have Speech Services supported (through the latest Web Chat) on Emulator very soon, and that progress can be tracked here.

This update would mean that bots using Speech Services can support speech. At the moment there is no plan to back-support Bing Speech in Emulator or Web Chat. For more information on Web Chat supporting Speech Services, please take a look at microsoft/BotFramework-WebChat#1336.
