Detailed Description

Functions for:

• Generating RFC and Tilt parameters from F0 contours
• Converting RFC to Tilt parameters and vice-versa
• Synthesizing F0 contours from RFC and Tilt events

Function Documentation

void default_rfc_params

(

EST_Features &

op

)

Fill op with sensible default parameters for RFC analysis.

Definition at line 106 of file tilt_analysis.cc.

void rfc_analysis	(	EST_Track &	fz,
		EST_Relation &	event_list,
		EST_Features &	op
	)

Produce a set of RFC parameterized events given approximate event boundaries and a smoothed F0 contour. See Producing an RFC representation from an utterance's events and F0 contour for a description of this process.

Parameters

f0	Smoothed continuous F0 contour. An error will occur if any unvoiced regions are detected in the contour. Use the function smooth_pda to smooth and interpolate a normal contour.
ev_list	list of events, each containing approximate start and end times of the events. On completion each event in this list will have a set of RFC parameters.
op	parameters used to control analysis process.

Definition at line 115 of file tilt_analysis.cc.

void tilt_analysis	(	EST_Track &	fz,
		EST_Relation &	event_list,
		EST_Features &	op
	)

Fill op with sensible default parameters for RFC analysis.

void fill_rise_fall_values	(	EST_Track &	fz,
		float	amp,
		float	start_f0
	)

Fill op with sensible default parameters for RFC analysis

void rfc_synthesis	(	EST_Track &	f0,
		EST_Relation &	ev_list,
		float	f_shift,
		int	no_conn
	)

Generate an F0 contour given a list RFC events.

Parameters

f0	Generated F0 contour
ev_list	list of events, each containing a set of RFC parameters
f_shift	frame shift in seconds of the generated contour
no_conn	Do not join events with straight lines if set to 1

Definition at line 116 of file tilt_synthesis.cc.

void tilt_synthesis	(	EST_Track &	track,
		EST_Relation &	ev_list,
		float	f_shift,
		int	no_conn
	)

Generate an F0 contour given a list Tilt events.

This function simply calls tilt_to_rfc followed by rfc_synthesis .

Parameters

f0	Generated F0 contour
ev_list	list of events, each containing a set of Tilt parameters
f_shift	frame shift in seconds of the generated contour
no_conn	Do not join events with straight lines if set to 1

Definition at line 47 of file tilt_synthesis.cc.

void tilt_to_rfc	(	EST_Features &	tilt,
		EST_Features &	rfc
	)

Convert a single set of local tilt parameters to local RFC parameters.

Parameters

tilt	input tilt parameters, named amp, dur and tilt
rfc	output RFC parameters, name rise_amp, fall_amp, rise_dur and fall_dur

Definition at line 197 of file tilt_utils.cc.

void rfc_to_tilt	(	EST_Features &	rfc,
		EST_Features &	tilt
	)

Convert a single set of local RFC parameters to local tilt parameters. See RFC to F0 Synthesis for a description of how this is performed.

Parameters

rfc	input RFC parameters, named rise_amp, fall_amp, rise_dur andfall_dur
tilt	output tilt parameters, named amp, dur and tilt

Definition at line 172 of file tilt_utils.cc.

void tilt_to_rfc

(

EST_Relation &

ev_tilt

)

For each tilt events in ev_tilt, produce a set of RFC parameters. The tilt parameters are stored as the following features in the event:

• tilt.amp
• tilt.dur

• tilt.tilt

  A set of features with the following names are created:

• rfc.rise_amp
• rfc.rise_dur
• rfc.fall_amp

• rfc.fall_dur

  The original tilt features are not deleted.

Definition at line 206 of file tilt_utils.cc.

void rfc_to_tilt

(

EST_Relation &

ev_rfc

)

For each tilt events in ev_rfc, produce a set of Tiltparameters. The RFC parameters are stored as the following features in the event:

• rfc.rise_amp
• rfc.rise_dur
• rfc.fall_amp

• rfc.fall_dur

  A set of features with the following names are created:

• tilt.amp
• tilt.dur

• tilt.tilt

  The original RFC features are not deleted.
