- Four open-source voice cloning models (OmniVoice, LongCat-AudioDiT, FireRedTTS-2, Fish Audio S2 Pro) now rival commercial TTS in quality and capability.
- OmniVoice supports over 600 languages with voice design features and fast inference, but requires clean audio for best results.
- LongCat-AudioDiT uses waveform latent space to skip spectrograms, achieving high speaker similarity, though its larger variant needs powerful GPUs.
- FireRedTTS-2 enables multi-speaker conversations with low latency and streaming, but is large and best for Chinese and English.
- Fish Audio S2 Pro offers granular emotional control via tags and near-human output, but has licensing restrictions and requires GPU for self-hosting.
- These models demonstrate open-source TTS has closed the gap with commercial options, offering diverse applications from multilingual to conversational voice generation.
