What is the difference between text to speech and AI-generated voice?
Text-to-speech
Text-to-speech (TTS) 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
AI voice generation, on the other hand, uses advanced AI algorithms trained on voice actors to produce high-quality voices that sound human. AI voice technology doesn’t simply convert text to speech; it creates an almost-human voice for engaging audio content. AI voice over generation tools often offer a variety of voice styles, 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, ads, e-learning, and more.
