Understanding AI Voices
Voice Quality Tiers
TTS.ai offers voices across three quality tiers. Free-tier voices from Piper, VITS, and MeloTTS deliver fast, good-quality synthesis at no cost. Standard-tier voices from models like Kokoro and CosyVoice 2 offer more natural prosody and emotion. Premium-tier voices from OpenVoice, Chatterbox, and StyleTTS 2 provide the most realistic, human-like speech available in open-source TTS.
多言語ボイス
Many voices support multiple languages. Some models like CosyVoice 2 and GPT-SoVITS support cross-lingual synthesis, where a voice trained in one language can speak naturally in another. The language filter above lets you find voices that natively support your target language, ensuring the best pronunciation and intonation.
Voice Cloning
Some models support voice cloning, which means you can use any voice as a reference to create speech that sounds like that person. Upload a short audio sample (10-30 seconds) and the model will adapt to match the voice characteristics. Models that support cloning include GPT-SoVITS, CosyVoice 2, and Chatterbox.
