Introducing the New Voice Interaction Feature with GPT AI

In this article, we will explore the latest feature added to version 1.3 of the GPT AI integration asset, now available on the Unity Asset Store. This new feature allows users to interact with Open AI or chat GPT using their voice. The AI then responds back to the user in its own generated voice. We will discuss how this feature can be used in-game, providing a dynamic and unscripted conversation with non-playable characters (NPCs). We will also walk through a demo scene included in the asset, showcasing the step-by-step process of voice interaction. So let's dive in and see how this innovative feature can elevate your game's storytelling and player experience.

1. Introduction

As voice-related technologies continue to advance, it is no surprise that integrating voice interaction into games has become a popular trend. The GPT AI integration asset, with its latest version 1.3 release, offers a cutting-edge solution to incorporate voice interaction with Open AI or chat GPT. This feature allows developers to create dynamic conversations with NPCs, responding to the user's voice input in the AI's own generated voice. With the ability to have natural and unscripted interactions, this feature opens up a world of possibilities for game developers to enhance player immersion and engagement.

2. Overview of the New Feature

The new voice interaction feature in the GPT AI integration asset leverages the capabilities of the Open AI Whisper API, which was released in March. This API enables the integration to transcribe audio into text, and then further process the text through the Open AI API to generate an AI response. Additionally, the integration incorporates the 11 Labs API, a service that utilizes AI to generate voices. With this powerful combination, developers can create realistic and personalized interactions between players and NPCs.

3. The Integration Asset: GPT AI

Before we delve into the details of the voice interaction feature, let's take a moment to understand the GPT AI integration asset itself. Developed by a team of experienced game developers, this asset provides seamless integration with the Open AI API, allowing developers to harness the power of AI-generated content in their games. The asset offers various features and functionalities that empower developers to create engaging and dynamic experiences for players.

4. How to Use the New Feature in Game

To utilize the voice interaction feature in your game, you need to follow a series of steps to set up the integration and configure the necessary settings. Although the demo scene provided with the asset demonstrates each step individually, in an actual game, these steps would be chained and linked together within a function to ensure a smooth user experience. Let's go through the step-by-step process of using the voice interaction feature in your game.

4.1 Demo Scene Walkthrough

The demo scene included with the GPT AI integration asset provides a basic understanding of how the voice interaction feature works. It is divided into five separate steps, illustrating the underlying processes. However, in a real game, these steps would be seamlessly integrated into a single function. The scene comprises a canvas with a text box to display AI responses, another text box to display transcribed text, and buttons to initiate different actions.

4.2 Recording and Transcribing Voice

The first step in utilizing the voice interaction feature is recording the user's voice. This can be achieved through the asset's voice recorder script. When the "Start Recording" button is clicked, the script searches for an available microphone and starts recording using the specified recording length, file name, and text completer. Once the user stops recording, the audio file is saved, and the script generates an audio clip in the scene's audio source.

4.3 Sending Text to the Open AI API

After the voice is recorded and converted into an audio clip, the next step is to transcribe the audio into text using the Open AI Whisper API. By clicking the "Transcribe" button, the audio clip is sent to the API, which transcribes the audio and returns the text. This transcribed text is then displayed in the white text box on the canvas, ready to be sent to the Open AI API for further processing.

4.4 Generating Voices with 11 Labs

Once we have the transcribed text, we can now send it to the Open AI API, utilizing the same process as a normal chat GPT prompt. This allows us to receive an AI-generated response. However, to make the interaction more immersive, we want the generated response to be delivered in the AI's own voice. This is where the 11 Labs API comes in. By sending the response to the 11 Labs API, we can generate a voice based on the AI's reply. The voice is then played, adding a more dynamic and authentic touch to the conversation.

4.5 Setting Up the Scene and Authenticating

To enable the voice interaction feature in your game, you need to set up the scene and authenticate your API key. The scene should include the Open AI completer, which serves as a container for authentication settings. The completer includes the API key and other necessary authentication details. Ensuring the completer is correctly placed within the scene guarantees that the feature will work seamlessly during gameplay.

4.6 Personalizing the AI's Personality

In addition to voice interaction, the GPT AI integration asset allows you to personalize the AI's personality. By using prompts, you can define the characteristics and behavior of the AI. For example, you can instruct the AI to act like a medieval-era woman who Speaks in an Old English dialect. By generating a prompt using the included prompt generator tool, you can easily specify the desired personality traits and expectations for the AI's responses.

4.7 Tweaking the Prompt for More Interesting Responses

To make the AI's responses more interesting, you can tweak the prompt instructions. By altering the prompt before sending it to the GPT AI API, you can influence the AI's creativity and style. For example, instead of providing a generic prompt like "Describe something about yourself in one sentence," you can add more specific instructions or context, resulting in more engaging and unique responses. Experimenting with different prompts allows for endless possibilities in the AI's generated content.

5. Technical Breakdown of the Code

To better understand the inner workings of the voice interaction feature, let's take a closer look at the code behind it. The code is structured in a way that handles the different API requests and creates a seamless flow of data between the Open AI and 11 Labs APIs. The voice recorder script handles the recording and saving of the user's voice, while the open AI demo script takes care of sending and receiving text to and from the AI. With the appropriate settings and authentication, the code ensures smooth communication between the integration asset and the APIs.

Overall, the new voice interaction feature with GPT AI offers game developers an innovative way to create immersive and dynamic conversations within their games. By utilizing the power of Open AI's Whisper API and the voice generation capabilities of 11 Labs, developers can enhance player engagement and storytelling. With the step-by-step guide provided in this article, you can begin implementing this feature into your game and explore the endless possibilities it offers.
