How does AI voice generation work? The process of generative robots and voice AI
How do you make a synthetic voice speak?
Artificial intelligence voice generation relies on a number of technological levers. Simply put, AI voice generation is a complex process, developed by experts, requiring the most advanced understanding of the sounds and modulations of the human voice. This involves two main AI principles built into every generator: text-to-speech technology and natural language processing.
- Text to speech (TTS)
This is the process of converting text into speech. The most popular TTS systems use deep learning techniques to produce voices that tend to resemble those of humans. Thanks to a learning model called Deep Neural Network (DNN), AI can learn the subtleties of the human voice from huge quantities of harvested data to generate a realistic, human-sounding result.
- Natural language processing (NLP)
This is AI that understands and uses human language, and is also used in systems such as ChatGPT. NLP must be part of the process for TTS to work properly: it enables the AI to understand the context, grammar and correct pronunciation of words in order to adapt the final wording of the message and make the result as natural as possible.
How do you transform text into automatic voice?
Why transform text into voice? Whether you're creating recordings, podcasts, audiobooks, music, audio guides, or audio descriptions, there's a lot of content out there today that encourages the addition of a voice-over or the creation of audio tracks on different platforms.
To transform text into voice, you'll need software or a service that uses the technologies we've just discussed. There are numerous applications available, ranging from free solutions to more advanced services for larger volumes of creation, depending on the level of authenticity required.
Beforehand, you need to write the text templates you want to turn into lyrics. Make sure your texts are clear and easy to understand, as AI works best with simple language templates, especially in French, as solutions currently analyze English texts more finely.
All you have to do is insert your text into the software or service and it will be transformed into sound in just a few seconds!
To help you choose the best solution, here's a list of 11 voice generators to discover right now to generate all your texts into voice before the market is completely saturated!
