The IBM Watson Text to Speech service is designed for streaming, low latency, synthesis of audio from text. It is the inverse of the automatic speech recognition. The TTS service can be accessed via a REST interface or directly via TCP.

1. Create a Bluemix Account

   Sign up in Bluemix, or use an existing account. Watson Services in Beta are free to use.

2. Download and install the Cloud-foundry CLI tool

3. Edit the manifest.yml file and change the <application-name> to something unique.

applications:
- services:
  - text-to-speech-service
  name: <application-name>
  command: node app.js
  path: .
  memory: 256M

The name you use will determinate your application url initially, e.g. <application-name>.mybluemix.net.

4. Connect to Bluemix in the command line tool.

$ cf api https://api.ng.bluemix.net
$ cf login -u <your user ID>

5. Create the Text to Speech service in Bluemix.

$ cf create-service text_to_speech standard text-to-speech-service

6. Push it live!

$ cf push

The application uses Node.js and npm so you will have to download and install them as part of the steps below.

1. Copy the credentials from your text-to-speech-service service in Bluemix to app.js, you can see the credentials using:

   $ cf env <application-name>

   Example output:

   System-Provided:
   {
   "VCAP_SERVICES": {
     "text_to_speech": [{
         "credentials": {
           "url": "<url>",
           "password": "<password>",
           "username": "<username>"
         },
       "label": "text_to_speech",
       "name": "text-to-speech-service",
       "plan": "free"
    }]
   }
   }

   You need to copy username, password and url.

2. Install Node.js

3. Go to the project folder in a terminal and run: npm install

4. Start the application

5. node app.js

6. Go to http://localhost:3000

To troubleshoot your Bluemix app the main useful source of information are the logs, to see them, run:

$ cf logs <application-name> --recent
