What's the difference between an AI voice generator and traditional text-to-speech?
Text-to-speech software
Text-to-speech technology takes written text and converts it into speech using a computer-generated voice.
These synthetic voices can sometimes sound robotic or monotonous. TTS is commonly used for navigation systems, screen readers, and automated phone systems.
A text-to-speech tool has limited capabilities in terms of naturalness and expressiveness, and may not provide the nuanced intonations and emotions required for sophisticated audio production.
Users often prefer using AI voice generators for more emotive content.
AI voice generator
An AI voice generator, on the other hand, uses advanced AI algorithms trained on natural human voices to produce ultra-realistic AI voices and AI narration.
AI voice technology doesn’t simply convert text to speech; it creates human-like voices for video voiceovers.
AI voiceover generation tools often offer a variety of voice options, languages, and accents, allowing users to select voices that align with their target audience.
This technology is particularly valuable for businesses looking to produce high-quality voiceovers for videos, e-learning, and more.
