Parameters

-ssp<em>signal	processing script The signal processing script used to preprocess the input data.
-c<em>corfname</em><a	name="spr_sel_frames.c" class="el"> Input corpus file name.
-sel<em>sel_string</em><a	name="spr_sel_frames.sel" class="el"> Unit name or state name (unit#nr). All frames corresponding to this string are copied to the output file.
-u<em>unitfilename</em><a	name="spr_sel_frames.u" class="el"> Unitfile name with all units for which frames should be selected (.arcd or .cd format). If unit of state based selection is asked for, or option -u should be given, or (with lower priority), option -sel.
-o<em>ofname</em><a	name="spr_sel_frames.o" class="el"> Output file name. If the selected frames are based on units or states, a second file, with same name but with extention 'siz' will give the length of all parts.
-suffix<em>file_extension</em><a	name="spr_sel_frames.suffix" class="el"> File name extention for an entry in the corpus file.
-margin<em>margin</em><a	name="spr_sel_frames.margin" class="el"> Frames are only copied starting from (Firstframe + margin) to (Lastframe - margin).
-nsel<em>NrSelected</em><a	name="spr_sel_frames.nsel" class="el"> Number of frames to select per state/unit/corpus. Default all.
-nfr_wanted<em>nfr_wanted_filename</em><a	name="spr_sel_frames.nfr_wanted" class="el"> Unitfile-like file with on each line a unit or state describing string and the number of frames wanted for that unit or state. Default is given with option -nsel. The number of lines can be indicated with the NLINES key.
-reduc<em>reduction</em><a	name="spr_sel_frames.reduc" class="el"> Reduction factor for the files in the corpus. Only every 'cor_reduc' different files, a file will be processed. Float values can be used, avoiding that in some cases, only files of one sort would be chosen.
-base<em>BaseFlag</em><a	name="spr_sel_frames.base" class="el"> Says if selection should be unit based (U), state based (S), or if frames should be selected from all data (C).
-obs<em>ObsDir</em><a	name="spr_sel_frames.obs" class="el"> Directory in which the files, listed in the corpus file, can be found.

Select frames corresponding to units or states, or to all data. This program extracts frames out of the data files listed in a corpus or segmentation file.

If the selection is corpus based (-base C), a number of frames from all data will be selected (option -nsel). If the selection is unit or state based (-base U or S), for each unit/state asked for, a number of frames (option -nsel and nfr_wanted) corresponding to that unit/state will be selected. Choose one unit/state with option -sel, or more by giving a unit file.

All frames are written in one file. If frames corresponding to units or states are asked for, a second file gives begin and end frame for each unit or state. If there are a lot of different files in the corpus file, one can ask to select e.g. 5 frames for each fifth different file in the corpus, instead of 1 frame for each file (option -reduc). It is possible to give a segment boundary margin so that frames within this margin from the boundary of a segment are not extracted.
