Getting Started

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-text-service
  name: <application-name>
  command: node app.js
  path: .
  memory: 128M

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 Speech to Text service in Bluemix.

$ cf create-service speech_to_text free speech-to-text-service

6. Push it live!

$ cf push

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

Running locally

The application uses [Node.js][http://nodejs.org/] and [npm][https://www.npmjs.com/] so you will have to download and install them as part of the steps below.

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

   $ cf env <application-name>

   Example output:

   System-Provided:
   {
   "VCAP_SERVICES": {
     "speech_to_text": [{
         "credentials": {
           "url": "<url>",
           "password": "<password>",
           "username": "<username>"
         },
       "label": "speech-to-text",
       "name": "speech-to-text-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
