[hts-users:02104] Re: Generation problems with 1mix

[Keiichiro Oura <uratec@xxxxxxxxxxxxxxx>]

Hi,

The differences between speech waveform generation are...

[1mix]
- Distributions: Single Gaussian distributions
- Variances: Diagonal covariance matrices
- Engine: HMGenS
[2mix]
- Distributions: Multi-variate Gaussian distributions (number of mixture is 2).
- Variances: Diagonal covariance matrices
- Engine: HMGenS
[stc]
- Distributions: Single Gaussian distributions
- Variances: Semi-tied covariance matrices
- Engine: HMGenS
[hts_engine]
- Distributions: Single Gaussian distributions
- Variances: Diagonal covariance matrices
- Engine: hts_engine

When you want to generate waveforms using HMGenS and unseen labels,
you must make mmf again (AU command of HHEd).

Regards,
Keiichiro Oura
