How to synthesize voice using a statistical model (e.g. DNN, HMM) with libllsm2?

Hi, thank you for the great job!

1. Can I use libllsm2 as vocoder for a statistical model ?
   I find feature's dimision in layer0 is different for each frame if the f0 is different. How should I use libllsm2 as a vocoder for a statistical acoustic model?
2. Can I implement similar features as synthesizer V by libllsm2?
   Synthesizer v can control parameters such as tension, breathness and achieve amazing results, and libllsm2 can distangle voice in harmonic signal and noise signal. Can I use libllsm2 implement similar features? Can you give me some tips about how to implement this function?

Thank you very much!
