What is Text To Speech?

Put simply, the name says it all. But if you're looking for more detail, we've got you covered. Text to speech is a form of speech synthesis, which is the artificial production of human speech. Software and hardware with TTS functions “read” and convert written text into speech. Text to speech converts your text into phonetic representations, and then converts that into waveforms that output as regular speech sounds.

Our text to speech engine is no different; it converts raw texts to written words and then assigns phonetic transcriptions to those words. Text to speech, also sometimes referred to as text to voice, is easily integrated into current marketing strategies across a variety of different industries. Businesses around the world have leveraged TTS for purposes ranging from marketing to education to recreation.

What is a WAV File?

WAV stands for Waveform Audio. These files are popular due to their high quality, uncompressed audio. They are also easy to access and convenient to use.
