Thanks to the rapid advances in artificial intelligence, AI voices are becoming increasingly commonplace in our daily lives. They power our GPS devices, read our audiobooks, and bring our virtual assistants to life.
But how do these AI voice generators And how do they manage to imitate the human voice? That's what we're going to find out together in this article.
The steps involved in generating an AI voice
Today, we're going to explore behind the scenes of the creation of an artificial voice and understand how AI voice generation tools work in general.

Step 1: Linguistic analysis
Before transforming a text into speech, the AI voice generator must understand its meaningThis involves analyzing grammatical structure, punctuation, vocabulary, and context.
Thus, AI can identify keywordsHe'll work out the most important phrases and the overall structure of the message to be conveyed. His aim is to understand what you've written, so as to generate an accurate and coherent voice-over.
Step 2: Converting text into phonemes
The AI then breaks down each word into its basic sound units, called phonemes. As a result, each broken-down sentence will be represented by a sequence of phonemes that forms the basis of speech.
For example, the word "house" is composed of phonemes /m/, /ɛ/, /z/, /ɔ̃/. This step is crucial in speech synthesis, as it enables AI to generate natural and intelligible sound.
Step 3: Creating the prosody
Prosody is the very essence of musicality voice, including intonation, rhythm, and speech rate.
AI relies on intelligent algorithms to determine the prosody best suited to your text. The aim is to bring your words to life by infusing them with the right emotion and tone.
Step 4: Voice-over synthesis
This is the final stage where AI combines phonemes and prosody to create a sound wave corresponding to the desired voice.
Generally speaking, an AI voice generator uses vocal techniques which are based on acoustic modeling and machine learning to achieve stunningly realistic results.
The usefulness of voice data for an AI voice generator
The quality of the voice generated depends heavily on the quantity and diversity of the voice data used to train AI voice generator algorithms. The richer and more varied the voice data, the more natural and convincing the AI voice will be.
This data can come from a variety of sources, including :
- The professional voice-over recordings,
- The audio book readings,
- The film and TV dialogue,
- The recorded voice conversations,
- Etc.
It is important that voice data is diverse in terms of age, gender, ethnicity, and accent. This will enable AI to generate more expressive and human voice-overs.
The different types of AI voice generators on the market
At present, the AI voice generation is in full swing, offering a multitude of solutions for bringing your texts to life.
To help you choose the right AI voice generator to your needs, we will introduce you to the different types of AI generators on the market:
