Text to Speech API

Text-to-Speech API allows you to convert written text into spoken words. The API supports multiple languages and can be integrated with any application for speech synthesis, voice assistants and accessibility.


About the API:


Our Text to Speech API is a powerful tool that allows you to convert written text into spoken words. The API supports multiple languages and can be integrated with any application for speech synthesis, voice assistants, and accessibility.

The API uses advanced natural language processing algorithms to analyze the input text and generate corresponding speech output with a natural-sounding voice. The output can be customized with different voices, language, and speech rate. This makes it an ideal tool for a variety of use cases such as speech synthesis, voice assistants, and accessibility.

The API can be integrated into any application to provide spoken feedback, such as reading text aloud, for users with visual impairments, or generating an audio version of written content, like books, articles and more. It can also be used to create voice assistants and chatbots, which can interact with users through speech.

In addition, the API can be used in other applications such as telephony systems, navigation devices, and other systems where speech synthesis is needed. It can also be used to generate audio clips of any text, useful for podcasting, video presentations, and more.

Overall, our Text-to-Speech API is a valuable tool for businesses and individuals looking to add speech synthesis capabilities to their applications. It is user-friendly, and easy to use and it supports multiple languages, making it accessible for a wide range of use cases and audiences.

Prices are based on a recurring monthly subscription depending on the plan selected โ€” plus overage fees applied when a developer exceeds a planโ€™s quota limits. In this example, you'll see the base plan amount as well as a quota limit of API requests. Be sure to notice the overage fee because you will be charged for each additional request.
