In recent years, the development of AI has revolutionized how we interact with technology. The development of AI voice generators and text-to-speech apps are one of the most important innovations. 

Take Speechify for example, which has a great improvement in accessibility of persons with sight problems and visual impairment which has led to application in different sectors. But a detailed process and significant investments are required to build an AI powered voice generator or TTS reader app such as Speechify. 

The key factors affecting the cost of developing a text to speech reader app like Speechify, and different components that contribute to its total price will be discussed in this blog. 

Global market share of text to speech technology

Factors to determine the cost of AI voice generator and Text-to-speech app development 

Research and Planning 

Thorough research and planning are the first important steps towards creating an AI Voice Generator and TTTS reader app. The scope of this project, setting specific objectives and conducting market studies are all part of this phase. 

By knowing the target audience and user requirements, you can enhance the predefined mobile app development process as well. The cost can be $2,000 to $10,000 or more in terms of complexity at the research and planning stages. 

Data Collection and Licensing 

A large amount of high-quality data needed to train machine learning models is required for the development of an efficient AI voice generator app. It can be a time consuming and costly process to collect and prepare the necessary data. 

Distribution of AI Voice Generation usage by peopleacc to their age

Depending on the size and source of the data, mobile app developers might also need to buy licenses for third party data sets and API's ranging between $100 and several thousand dollars. 

AI & Machine Learning Development 

Machine learning algorithms are at the heart of the AI voice generator and TTS reader applications. There is an enormous amount of computational power and expertise needed to train AI and machine learning models. Algorithms' complexity and developers' expertise are essential for the cost of developing AI. Approximately $10,000 to $50,000 will come as an overall cost for AI & ML integration. 

Backend Development 

A robust backend infrastructure is needed to provide a seamless user experience. This requires the development of server, database, API, and cloud managed solutions. The development cost of the backend shall be determined by app size and choice of hosting service. Depending on the application's complexity and its expected user base, it can range from $10,000 to $30,000. 

Frontend Development 

User interfaces and experience design are key focal areas for frontend developers. It takes talented designers and developers to create a user interface that is intuitive and visually appealing. Depending on the number of features and screens, typical costs for frontend development could range from $10,000 to $25,000. 

Platform Compatibility 

The development costs are increased by making the app compatible with different platforms, such as iOS, Android, and Web browsers. It increases costs to develop the native app for each platform, while cross-platform app development tools such as React Native can help reduce those costs. The range of this stage may be between $5,000 and $20,000. 

Integration of Features 

The overall usefulness of the app is enhanced by additional features such as text highlighting, bookmarking and cloud sync. The complexity and time it takes to implement these features determines the costs of integrating them. Approximately $5,000 to $15,000 may be required for this phase.

Testing and Quality Assurance 

To ensure user satisfaction, you need to make sure your app runs perfectly on all types of devices and scenarios. Identifying and fixing the bugs, conducting user testing to ensure compliance with accessibility standards shall form part of the app test and quality assurance phases. Depending on how much testing is needed, the cost of this stage may be between five and fifteen thousand dollars. 

Security and Data Privacy 

The security aspect is particularly important in dealing with sensitive user data. The development cost may increase from $5,000 to $15,000 if security measures are introduced and data privacy regulations are complied with. 

Maintenance and Updates 

Maintaining and updating the app regularly after its launch is essential to ensure a smooth application, as well as introducing new features. Depending on the complexity of the application and its update frequency, maintenance costs may vary by as much as 20 or 30 % per year from initial development costs. 

Additional factors that affect cost of AI voice generator app development 

  • User Experience (UX) Design 

User experience is an essential element of any successful application. User engagement and satisfaction can be significantly influenced by investments in user interface design including UI/UX and UWP. Depending on the complexity of your app's interactions, the costs can vary from $5,000 up to $15,000 for user experience designing. 

  • Natural Language Processing (NLP) Integration: 

As an essential component of the Voice Generator and TTS Reader app, NLP algorithms have a fundamental role to play in understanding and processing human language. Depending upon the extent to which you integrate NLP capabilities, it may increase your development costs by $10,000 to $30,000 or more.

  • Customization & Personalization 

The value of this application is to allow users to customize the experience when they read by selecting their favorite voices, accents or reads at an accelerated rate. A cost of $5,000 to $10,000 could be added to the implementation of the customization features. 

  • Cloud Services & Storage 

Strong cloud infrastructure is needed for the storage and management of vast amounts of data. To reduce server costs and increase scale, the integration of cloud services can be beneficial. Depending on how much you use it, the monthly cost of cloud services can be between $100 and a few thousand dollars. 

  • Licencing & Legal Considerations 

Licensing fees and the law may also be involved in applying artificial intelligence and third-party technologies. Licenses may cost between $5,000 and $15,000, depending on the type of voice models or mobile app technologies already in use. 

  • Accessibility Compliance 

To reach a broader audience, including people with disabilities, it is important to ensure that the accessibility standards are respected. Depending on the requirements, the cost of compliance with accessibility standards could vary from $2,000 to $10,000. 

  • Marketing an& Distribution 

The promotion and distribution of the app is key to reaching potential users once it has been developed. Marketing strategies, optimization of app stores and advertising campaigns may run from $5,000 to $20,000 depending upon the marketing scope. 

  • Customer Support & Updates 

When you’re looking to retain users, it is necessary to provide reliable customer support and regularly update the app. Approximately 20% to 30% of the original development cost may be earmarked every year for continuing support and updates. 

  • Competitor Analysis 

It is possible to gain insight into existing market players and their products by conducting a competitor analysis. It can cost as much as $2,000 or $5,000 to understand the competitive landscape.  

  • Monetization Strategies 

To generate revenue, it may be helpful to explore various monetization strategies including subscription models for in-app purchases or advertising. There are development and maintenance costs for each strategy, and the choice of approach may affect the overall financial outlook. 

Key takeaways 

It's a complex and resource intensive process to build AI voice generators or TTS reader apps like Speechify. Costs vary from one factor to another, such as the scope of the app, its features, platform compatibility and data requirements. Due consideration of target audience and specific user needs must be considered when planning the project. 

The potential advantages for accessibility, user satisfaction and market potential may also be significant considering the investment required to build such an application.
