Text to Speech (TTS) Audio Explained

Text-to-speech technology is a program that inputs the text and converts it into audible speech as a result. In simple words, it goes from text form to speech form, making text-to-speech technology a digital revolution. While doing TTS, you need software that can remarkably predict the best pronunciation, expression, and tonality of the given text. It is also possible for you to select the voice waves available as options on the program. Text-to-speech is a multidisciplinary realm and needs detailed knowledge. To gain perfection in it, you should know its method and theory.

These Are The Following Subjects To Know About:

  • Linguistics, the language study: To synthesize good speech, TTS recognizes the pronunciation of written language by a human. It needs the knowledge of linguistics to the phoneme standard. To get the best humanlike TTS results, the system should also estimate suitable prosody that includes elements more than phonemes, such as pauses, stresses, and expressions.
  • Audio signal processing and digital sound production: Audio signals electronically represent sound waves. They are created digitally as numerical sequences. Hence, speech scientists use a different feature of speech signals trained to generate new speech.
  • AI, ML, and deep learning produce deep neural networks: A neural network is inspired by the human brain. A deep neural network learns the best processes to produce accurate results, making it ideal to handle several variables needed for high-quality speech synthesis.

What Is Text-To-Audio Technology?

The simple to use method to convert text-to-speech audio includes the following steps:

  • Convert text to words

Firstly, the software converts the text into a simple-to-read format. The challenge is to check out the numbers, dates, and abbreviations. It should be translated into one form so that the software can read it in one go.

The system then reads different phrases with suitable intonation, following the punctuations, vocabulary, and stable structure. 

  • Phonetic transcription

Every sentence can be pronounced in its required tone depending on its meaning and expression. To understand its meaning, the systems have in-built dictionaries. There are over 570 voices that can be used for text-to-speech audio to match the project requirement. 

The software creates the suitable intonation and expression using data and presents the text in the tone the way it should be.

  • Transform transcription to speech

Lastly, the software uses an acoustic model to assess the text. The ML algorithm sets up the link between phonemes, sound, tones, expression, and the voice selected, creating precise intonation. Using a voice generator, the vocal sound is produced.

Play.ht is an AI voice text-to-speech generator program that helps people convert any text into speech. There is no need for you to be tech-savvy to use it. You have to highlight the text you want to convert, choose your customization option and voice that goes with your text and click on convert. The audio clip will be in front of you in a few minutes. It is a simple-to-use, convenient and affordable option that companies can choose to meet their text-to-speech requirements.
