Usage with C#
dotnet add package ElBruno.QwenTTS.VoiceCloning
using ElBruno.QwenTTS.VoiceCloning.Pipeline;
var cloner = await VoiceClonePipeline.CreateAsync();
await cloner.SynthesizeAsync("Hello world!", "reference.wav", "output.wav", "english");
Architecture
- Speaker Encoder: ECAPA-TDNN, 128 mel bins input, 1024-dim output
- Talker: 28 transformer layers, 16 attn heads, 8 KV heads, hidden=1024
- Code Predictor: 5 layers, generates codebook groups 1-15
- Vocoder: RVQ dequantize → transformer → BigVGAN decoder, 12Hz → 24kHz
