How do they work, and what are their features?

There are a few different types of text to speech APIs. Some common functionality features among them are: the ability to automatically identify the language of the text, support for a wide range of languages and dialects, the ability to convert text to speech in real time, and support for various output formats such as MP3 or WAV. 

The most common type of text to speech API is based on what is known as a TTS engine. A TTS engine takes written text and converts it into spoken words using digital signal processing algorithms. There are a few different types of TTS engines, but they all work essentially the same way. Another type of text to speech API is based on pre-recorded audio files. These APIs take advantage of the fact that human voice actors have already recorded a large number of words and phrases in various languages. 

By using these recorded audio files, text to speech APIs can provide high-quality audio output without the need for a TTS engine. However, these types of APIs typically only support a limited number of languages and often don’t offer real-time conversion.

Who are they best for, and what industries can benefit from them?
