Loading the Model

from qwen_tts.inference.qwen3_tts_model import Qwen3TTSModel

# Load the fine-tuned model
model = Qwen3TTSModel.from_pretrained(
    "./output/checkpoint",
    torch_dtype=torch.bfloat16,
    attn_implementation="flash_attention_2"
)

# Generate speech with the new speaker
text = "Your text here"
ref_audio = "path/to/reference_audio.wav"

wavs, sr = model.generate_voice_clone(
    text=text,
    language="Auto",
    ref_audio=ref_audio,
    ref_text="Reference text for ICL mode",
    x_vector_only_mode=False
)

Speaker Information

The model has been fine-tuned for speaker: hausa_speaker Speaker embedding is stored at index 3000 in the codec embedding layer. Speaker encoder weights are included in the checkpoint and have been fine-tuned.

Notes

• This model uses the Qwen3-TTS tokenizer
• The model supports streaming generation
• For best results, use reference audio from the same speaker used during training
• The speaker encoder has been fine-tuned to better capture speaker characteristics
