When 15.ai went offline, it left a significant void for users who relied on its realistic and character-driven voice generation. In response, I tested numerous alternatives to find tools that offer smooth, emotional, and character-style voiceovers. This article presents six of the best alternatives I’ve explored.
15.ai was a popular AI voice generator known for its ability to create realistic voices of beloved characters like SpongeBob and GLaDOS. Despite its success, it went offline in September 2022 and only returned in May 2025 as 15.dev. Due to its long absence, many users remain hesitant to rely on it again.
To fill this gap, I examined more stable and actively maintained alternatives. These tools not only match but sometimes exceed 15.ai’s offerings. Here are six standout options:
1. ElevenLabs: Renowned for realistic and emotionally expressive voice generation, it supports over 30 languages and offers instant voice cloning.
2. Uberduck: Known for character voiceovers and meme audio, it provides a vast library of AI-generated voices and features like AI-generated rap.
3. Voicemod: Offers real-time voice modulation and meme audio, with features like Text to Song and custom voice effects.
4. Resemble AI: An enterprise-grade platform for voice cloning, it offers capabilities like text-to-speech and speech-to-speech conversion.
5. Play.ht: Ideal for podcasting and audiobooks, it boasts a library of over 600 AI voices across 100+ languages.
6. Descript Overdub: Integrated into a full media editing platform, it allows for seamless voice cloning and text-based audio editing.
Each tool has unique strengths, catering to different needs, whether for narration, creative content, or professional voiceovers. The best choice depends on your specific requirements, but these alternatives provide robust options to replace the void left by 15.ai.
