How to Develop an AI Text-to-Speech App

The step-by-step guide to developing an AI-based text-to-speech app is as follows:

  1. Define the Requirements

To develop an AI text-to-speech app, the first and foremost step is to define the requirements for text-to-speech app development in detail. 

Understand the app’s purpose, its target audience, top-notch features and functionalities, and platforms it will support – Android, iOS, or cross-platform app development

  1. Set Up the Development Team

You will need to hire top AI app developers to build your AI-enabled text-to-speech mobile app. You can also outsource the app development to a leading mobile app development company that has expertise in developing AI text-to-speech apps. 

  1. Data Collection and Preprocessing

To train the AI text-to-speech model, you will need to gather a diverse dataset of text and matching audio recordings. Once you gather the text with audio recordings, clean and preprocess it thoroughly to ensure high-quality results. 

The data preprocessing includes: 

  • Text Normalization: the process of converting raw text into a standardized or canonical form. 
  • Tokenization: the process of breaking down a text or a sequence of characters into smaller units called tokens. 
  • Audio Feature Extraction: the process of extracting relevant features or characteristics from audio signals that capture important information about the sound’s properties, such as pitch, amplitude, frequency, and duration. 
  1. Model Training

After preprocessing the data, train the text-to-speech model leveraging deep learning techniques, such as recurrent neural networks (RNNs), convolutional neural networks (CNNs), or transformer architectures. 

You must fine-tune the model on the dataset you collected to optimize its performance and generate accurate results.  

  1. Test the Trained Model

Conduct rigorous testing of the trained model to ensure it is working precisely and delivering accurate results without any errors with different text inputs and languages.

  1. Design the UI 

With the assistance of UI designers, design an intuitive user interface for the text-to-speech app, having well-arranged icons and templates. 

The UI must be de-cluttered, allowing users to enter text, customize speech parameters, such as tone, speed, and voice level, and get desired speech results. 

  1. Develop the Text-to-Speech App 

Once the UI is designed, code the frontend and backend components of the AI text-to-speech app. Also, integrate the trained model into the app’s backend infrastructure. 

You need to ensure that the trained model communicates with other components, such as databases, Application Programming Interfaces (APIs), and user interfaces of the app seamlessly while developing the app.  

  1. Testing the App 

Post-development, test the AI text-to-speech app to identify bugs and fix them immediately. Moreover, evaluate the app’s compatibility with various devices and platforms, such as Android and iOS.  

You can also launch the Beta version of the app to test its functionality and performance and gather feedback from users simultaneously. 

  1. Launch the App 

After testing is done and your mobile app developers have made the necessary changes in the app, you can launch your AI text-to-speech app on Playstore and App Store. 

Moreover, you can also launch your AI text-to-speech app on cloud platforms like Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform (GCP), to align with the growing trend of cloud-based apps

  1. Regular Maintenance and Updates 

The job isn’t finished with the launch of the app. You need to monitor the performance of your AI text-to-speech app regularly. 

Also, you must keep integrating novel technologies and functionalities and fix bugs to keep the app relevant in the market for a long time.

So, this is how you develop an AI text-to-speech app. We have covered all the major stages of the development process. Still, if you need assistance regarding text-to-speech app development, reach out to our team!
