What Is A Text-to-Speech Call API?
A text to speech or TTS API is a defined set of instructions which enable systems to send text based messages via an online gateway that then converts the text to voice message which calls your recipient's phone. A TTS API is used to add text to speech capability to your existing software and applications.
