In this post, we’ll go through Text-to-Speech APIs and the finest APIs for incorporating into your software.
What is Text-to-Speech API?
Text-to-speech (TTS), often known as speech synthesis, is the process of translating written text to spoken sounds. In most circumstances, text-to-speech refers to the text on a computer or other device.
The Text-to-Speech API allows developers to create human-like speech. The API translates text to audio formats such as WAV, MP3, and Ogg Opus.
It also accepts Speech Synthesis Markup Language (SSML) inputs to set pauses, numerals, date and time formatting, and other pronunciation commands.
It can be used to allow speech-based text output in an app or application in addition to presenting text on a screen.
