How AI Voice Generators Work
AI voice generators utilize deep learning and neural networks to synthesize realistic humanlike voices. The AI is trained on huge datasets of real human speech to learn the patterns and recreate a similar voice.
Key components that allow an AI to generate voices:
Text-to-speech Technology
The text-to-speak (TTS) system converts text into speech based on rules about pronunciation, pitch, emotion, pauses, etc.
Large Speech Databases
The AI learns from thousands of audio samples of real human voices reading passages. This allows it to mimic human speech.
Neural Networks
The deep neural net architecture processes the text and audio data, extracting patterns to build a synthetic voice model.
