Text to Speech Python Starter Application

The Text to Speech service uses IBM's speech synthesis capabilities to convert English or Spanish text to an audio signal. The audio is streamed back to the client with minimal delay. The service can be accessed via a REST interface.

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

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:
- name: text-to-speech-python
  command: python server.py
  path: .
  memory: 256M
  services:
  - text-to-speech-service

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 free text-to-speech-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 Python and pip 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": "text_to_speech_free_plan"
 }]
}
}

You need to copy `username`, `password` and `url`.

2. Install Python 2.7.9 or later
3. Go to the project folder in a terminal and run: pip install -r requirements.txt
4. Start the application python server.py
5. Go to http://localhost:3000

Troubleshooting

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

$ cf logs <application-name> --recent
