getTargetCostFunction

public TargetCostFunction getTargetCostFunction()

getJoinCostFunction

public JoinCostFunction getJoinCostFunction()

getUnitFileReader

public UnitFileReader getUnitFileReader()

getAudioTimeline

public TimelineReader getAudioTimeline()

getSCostFunction

public StatisticalCostFunction getSCostFunction()

getCandidates

public List<ViterbiCandidate> getCandidates(Target target)

Preselect a set of candidates that could be used to realise the given target.

Parameters:

target - a Target object representing an optimal unit

Returns:

an unsorted ArrayList of ViterbiCandidates, each containing the (same) target and a (different) Unit object

getFilenameAndTime

public String getFilenameAndTime(Unit unit)

For debugging, return the basename of the original audio file from which the unit is coming, as well as the start time in that file.

Parameters:

unit - unit

Returns:

a String containing basename followed by a space and the unit's start time, in seconds, from the beginning of the file. If no basenameTimeline was specified for this voice, returns the string "unknown origin".

getFilename

public String getFilename(Unit unit)

For debugging, return the basename of the original audio file from which the unit is coming.

Parameters:

unit - unit

Returns:

a String containing basename. If no basenameTimeline was specified for this voice, returns the string "unknown origin".
