Introduction

Artificial Intelligence (AI) has revolutionized various industries, and today we'll explore how to incorporate AI into a Rails application. Specifically, we'll focus on setting up a chat input feature that utilizes an AI voice generation service called 11 Labs. By creating a voice profile and leveraging the 11 Labs API, we can generate audio Based on user Prompts. This article will guide You through the steps necessary to integrate AI voice generation into your Rails application.

Setting up the Rails Application

To get started, we'll first set up a Rails application. We'll Create a new project using the Rails command and configure additional dependencies such as Tailwind CSS. By following these steps, we'll have a solid foundation for integrating AI voice generation.

Creating a Voice Profile on 11 Labs

Before we can generate audio using 11 Labs, we need to create a voice profile. This involves signing up for an account on the 11 Labs Website and setting up your own voice. We'll explore the options available for customization and learn how to obtain an API key for authentication purposes.

Exploring the API Endpoints

The 11 Labs service offers various API endpoints that allow us to Interact with their voice generation functionality. We'll review these endpoints and understand how they fit into our Rails application. From creating voice recordings to tweaking voice settings, we'll gain a comprehensive understanding of the available API functionalities.

Configuring the API Key in Rails

To access the 11 Labs API, we need to configure our Rails application with the API key. We'll explore the Rails credentials feature and securely store our API key. Following the steps outlined in this section, you'll be able to access the API key within your Rails code.

Generating the Home Page

In this section, we'll create the home page of our application. This page will display the chat input feature and the generated audio responses. By leveraging Rails' generator commands, we'll create the necessary controller and views for the home page. We'll also integrate Turbo Streams to enable real-time updates.

Creating the Audio Model

To organize and manage the audio files generated by the AI voice service, we'll create an Audio model. This model will have attributes such as the user's prompt and the corresponding audio file. We'll utilize Rails' Active Storage feature to handle file attachments and create the necessary database migrations.

Implementing the Text-to-Speech Job

To handle the asynchronous generation of audio, we'll create a Text-to-Speech job. This job will be responsible for sending the prompt to the 11 Labs API, receiving the generated audio, and saving it to the corresponding Audio Record. By utilizing Active Job and Faraday gem, we'll seamlessly integrate the API functionality into our Rails application.

Displaying Previous Responses

In this section, we'll modify the home page to display the previously generated audio responses. We'll retrieve the Audio records from the database and render them on the page using partials. By implementing this feature, users can easily access and replay their previous audio recordings.

Broadcasting and Streaming with Turbo

To provide a smooth real-time experience, we'll utilize Turbo Streams and Broadcasting. Whenever a new audio response is generated, we'll broadcast the update to all connected clients using Action Cable. By leveraging Turbo Streams' append functionality, we'll dynamically update the page with the latest audio recordings.

Setting up the Rails Application

In order to integrate AI voice generation capabilities into a Rails application, we first need to set up the project. We'll start by creating a new Rails application and configuring any additional dependencies we'll be using. For this tutorial, we'll also be integrating Tailwind CSS for styling purposes. Once the initial setup is complete, we can proceed to the next steps of creating a voice profile and exploring the API endpoints.

Creating a Voice Profile on 11 Labs

To utilize the AI voice generation service provided by 11 Labs, we need to create a voice profile. This involves signing up for an account on the 11 Labs website and setting up a custom voice. With a Creator subscription, users can record their own voice and tweak various settings to generate unique audio. It is vital to adhere to ethical guidelines and use only our own voice for recording purposes. Once the voice profile is set up, we can proceed to integrating it into our Rails application.

Exploring the API Endpoints

The 11 Labs API offers several endpoints that allow us to interact with their voice generation service programmatically. By understanding the available endpoints and their functionalities, we can effectively integrate them into our Rails application. These endpoints enable us to create voice recordings, customize voice settings, and retrieve audio samples. It is important to carefully review the API documentation to make the most of these functionalities.

Configuring the API Key in Rails

To access the 11 Labs API, we need to configure our Rails application with the API key. This API key serves as an authentication mechanism and allows us to make requests to the API. By utilizing Rails' credentials feature, we can securely store the API key and access it within our Rails code. We'll create the necessary configuration files and update them with the API key obtained from 11 Labs. With the API key properly configured, we can proceed to implement the AI voice generation feature in our application.

Generating the Home Page

The home page of our Rails application will serve as the interface for users to enter their prompts and generate audio responses. We'll create the necessary controller and views to handle this functionality. The home page will feature a form where users can input their prompts, triggering the audio generation process. We'll utilize Rails' form helpers to create an intuitive user interface. Additionally, we'll incorporate Turbo Streams to enable real-time updates, ensuring a seamless user experience.

Creating the Audio Model

To manage the audio files generated by the AI voice service, we'll create an Audio model. This model will have attributes such as the prompt and the corresponding audio file. We'll utilize Rails' Active Storage functionality to handle file attachments and storage. By creating the necessary database migrations, we'll ensure the persistence of audio records. With the Audio model in place, we can easily manage and retrieve the generated audio files.

Implementing the Text-to-Speech Job

The process of generating audio files using the AI voice service will be handled asynchronously using Active Job. We'll create a Text-to-Speech job that encapsulates the logic for sending prompts to the 11 Labs API and saving the resulting audio files to the respective Audio records. By leveraging the Faraday gem, we can easily make HTTP requests to the API and process the response. We'll explore how to configure and execute the Text-to-Speech job within our Rails application.

Displaying Previous Responses

In order to provide users with easy access to their previous audio recordings, we'll enhance the home page to display a list of the generated audio responses. We'll retrieve the Audio records from the database and render them on the page using partials. With the implemented feature, users can review and replay their previous prompts and corresponding audio. This adds to the overall user experience and facilitates the utilization of the AI voice generation service.

Broadcasting and Streaming with Turbo

To ensure a smooth and real-time experience for users, we'll leverage Turbo Streams and Broadcasting capabilities. Whenever a new audio response is generated, we'll broadcast the update to all connected clients using Action Cable. By appending the new audio recordings to the page dynamically, users can Instantly see the generated audio without the need for manual refreshing. This enhances the interactivity and responsiveness of the application.
