AI voice generation technology has progressed by leaps and bounds, now rivaling human vocal qualities.
The market for AI voice generators reached an estimated $1.396 billion in 2023. Experts predict up to 15.4% growth annually, rising exponentially to $4.89 billion by 2032. More and more companies create voiceovers for AI-generated videos, narrations, phone menus, and other audio using AI.
But with several new AI voice startups available, it’s hard for developers to pick the right tool for their application and budget.
By comparing features, pricing, and AI features, this guide will help you understand the best software for your application.
What is an AI Voice Generator?
An AI voice generator refers to software that leverages artificial intelligence to synthesize human-like speech from text input. They convert typed words into realistic audio readings using advanced neural networks trained on enormous datasets of vocal patterns.
Key capabilities of AI voice generators include:
- Text-to-speech with adjustable pitch, tone, and cadence to sound natural
- Voice cloning to recreate the speech style of an existing person
- Custom vocabulary for accurate pronunciation
- Support for multiple languages and accents
- Background noise cancellation for clarity
- Integration of synthesized narration into videos, prototypes, and more
AI voice generators aim to produce extremely high-quality and expressive computer-generated speech that resembles human vocals.
