The application uses IBM's speech recognition, machine translation, and voice synthesis capabilities to instantly translate speech to another language and read the translation aloud.

Node.js is used to provide the browser client's authentication token.

Give it a try! Click the button below to fork into IBM DevOps Services and deploy your own copy of this application on Bluemix.

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:
  - speech-to-speech-service-standard
  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. Install Node.js

5. Install project dependencies and build browser application:

$ npm install && npm run build

6. Connect to Bluemix in the command line tool.

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

7. Create the Speech to Speech service in Bluemix.

$ cf create-service speech_to_speech standard speech-to-speech-service-standard

8. Push it live!

$ cf push

See the full Getting Started documentation for more details, including code snippets and references.

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 speech-to-speech-service-standard service in Bluemix to app.js, you can see the credentials using:

   $ cf env <application-name>

   Example output:

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

   You need to copy username, password and url.

2. Install Node.js

3. To install project dependencies, go to the project folder in a terminal and run:

   $ npm install

4. Then, build the browser application using Browserify:

   • To build with debugging enabled, and rebuild if the app is changed:

   $ npm run watch

   • To simply build the application without debugging or file-change monitoring:

   $ npm run build

5. Start the application:

   $ 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
