​
Configuring the package

Once you’ve added the package to your project (see Installation Guide), you’ll need to configure it with an API key. Select LMNT > Configure API Key... from the menu bar. Configure API Key You can get a new API key or find your current key by pressing the Get an API key... button. Get an API key Once you’ve pasted your key into the input box, press the Save button to continue. That’s it! You’re all set to add dialogue to your game objects.

​
Adding dialogue to a GameObject

Select a GameObject that you want to speak, and add an LMNT Speech Component in the Inspector. Add LMNT Speech Component Now, choose a voice from the drop-down list and write some text you’d like the GameObject to say. Configure LMNT Speech Component

​
Triggering dialogue from a script

Now that your GameObject’s dialogue is configured, you can trigger it from a script. The easiest way to do that is by adding the following code to your MonoObject: 
public class MyScript : MonoBehaviour {
  private LMNTSpeech speech;

  void Start() {
    // ... your code here ...
    speech = GetComponent<LMNTSpeech>();
  }

  void Update() {
    // ... your code here ...
    StartCoroutine(speech.Talk());
  }
}
For a detailed example, you can read through the DialogueTriggerScript.cs file in the LMNT package.

​
Changing dialogue at runtime

You can also use your script to change the dialogue at runtime. For example, you can change the text to be spoken by the GameObject by calling speech.dialogue = "New text to say";. This will overwrite the text you wrote in the Inspector. 
public class MyScript : MonoBehaviour {
  private LMNTSpeech speech;

  void Start() {
    speech = GetComponent<LMNTSpeech>();
  }

  void Update() {
    speech.dialogue = "New text to say";
    StartCoroutine(speech.Talk());
  }
}
