Notable capabilities (3)
- Small open multilingual zero-shot TTS: 0.5B model with 9 languages (zh, en, ja, ko, de, es, fr, it, ru) and 18+ Chinese dialects/accents; RL variant reports 0.81% CER / 77.4% speaker similarity (zh) and 1.68% WER / 69.5% similarity (en) on its eval set. source
- Compact far-field ASR (Fun-ASR-Nano, 800M): zh/en/ja plus 7 Chinese dialect groups and 26 accents; WER 1.80% AIShell1, 1.76% LibriSpeech-clean; tuned for noisy far-field audio and lyrics over music. MLT-Nano variant covers 31 languages. source
- Open 8B speech chat model with function calling (Fun-Audio-Chat): Half-duplex speech-to-speech/speech-to-text LLM (zh/en) with dual-resolution speech representations (5 Hz backbone + 25 Hz head, about 50% less compute); spoken QA, speech function calling, voice empathy. source
