public AliasDiphone(java.lang.String name,
                    java.lang.String originalName)

Parameters:

name - The alias name to use for the existing diphone

originalName - the original name of the diphone.

Method Detail

getOriginalName

public java.lang.String getOriginalName()

Get the name of the original name that this alias points to.

setOriginalDiphone

public void setOriginalDiphone(Diphone original)

Associate the actual diphone object of the original with this alias.

Parameters:

original - a diphone object whose getName() must return the same as our getOriginalName().

Throws:

java.lang.IllegalArgumentException - if the diphone to be registered as the original has a name which is different from this AliasDiphone's original name as returned by getOriginalName().

getSamples

public Sample[] getSamples()

Returns the samples associated with this diphone.

Overrides:

getSamples in class Diphone

Returns:

the samples associated with this diphone

getSamples

public Sample getSamples(int which)

Returns a particular sample.

Overrides:

getSamples in class Diphone

Parameters:

which - which sample to return

Returns:

the desired sample

getMidPoint

public int getMidPoint()

Returns the midpoint index. the midpoint index is the sample that divides the diphone into the first and second parts.

Overrides:

getMidPoint in class Diphone

Returns:

the midpoint index.

getPbPositionMillis

public int getPbPositionMillis()

Returns the midpoint index. the midpoint index is the sample that divides the diphone into the first and second parts.
