# tilt_synthesis Generate F0 contours from Tilt descriptions

## Synopsis

tilt_synthesis [input label file] -o [output file] [options]Summary: generate F0 file from tilt or RFC label file [-h ] [-noconn ] [-o `ofile`] [-otype `string`] [-event_names `string`] [-s `float`]

tilt_synthesis generates a F0 contour, given a label file containing parameteriszed Tilt or RFC events. A detailed description of the Tilt intonation model can be found in the Tilt model overview section.

## OPTIONS

> -h | Options help
> -noconn | Synthesize events only - no connections in output
> -o | `ofile` Output F0 file
> -otype | `string` File type for output label file
> -event_names | `string` List of labels to be classed as events. Lists are specified as quoted strings with spaces separating each item, e.g.: "a b c d"
> -s | `float` Frame spacing of generated contour in seconds

## Input Intonation Files

The input should be a label file containing the tilt parameters for the events in feature format. An example, in xlabel format, is shown below:

intonation_style tilt # 0.29 26 phrase_start ; ev.f0 115.234 ; position 0.29 ; 0.53 26 a ; int_event 1 ; ev.f0 118.171 ; position 0.53 ; tilt.amp 21.8602 ; tilt.dur 0.26 ; tilt.tilt -0.163727 ; 0.77 26 a ; int_event 1 ; ev.f0 112.694 ; position 0.77 ; tilt.amp 27.0315 ; tilt.dur 0.32 ; tilt.tilt -0.446791 ; 1.53 26 a ; int_event 1 ; ev.f0 100.83 ; position 1.53 ; tilt.amp 7.507 ; tilt.dur 0.22 ; tilt.tilt -0.296317 ; 1.79 26 phrase_end ; ev.f0 92.9785 ; position 1.79 ;

tilt_synthesis can also generate F0 contours from RFC parameters:

intonation_style rfc # 0.29 26 phrase_start ; ev.f0 115.234 ; position 0.29 ; 0.53 26 a ; ev.f0 118.171 ; rfc.rise_amp 8.19178 ; rfc.rise_dur 0.12 ; rfc.fall_amp -13.6684 ; rfc.fall_dur 0.14 ; position 0.53 ; 0.77 26 a ; ev.f0 112.694 ; rfc.rise_amp 6.50673 ; rfc.rise_dur 0.1 ; rfc.fall_amp -20.5248 ; rfc.fall_dur 0.22 ; position 0.77 ; 1.53 26 a ; ev.f0 100.83 ; rfc.rise_amp 1.55832 ; rfc.rise_dur 0.11 ; rfc.fall_amp -6.09238 ; rfc.fall_dur 0.11 ; position 1.53 ; 1.79 26 phrase_end ; ev.f0 92.9785 ; position 1.79 ;

The feature in the header, "intonation_style tilt" or "intonation_style rfc" is needed for the tilt_synthesis program to know which type of synthesis to perform.
