[hts-users:03906] Re: Clustering all phones

[Keiichiro Oura <uratec@xxxxxxxxxxxxxxx>]

Hi,

As you said, in speech recognition, "current phoneme identity" context
is usually treated as a special context.
However, in HTS-demo scripts, "current phoneme identity" context is
regarded as one of the many context factors to be considered.
So, the similar phonemes can share some leafs.
