After <EM>sdcomp</EM> starts and after a portion is played from each file, the user is prompted for the next action. The follow- ing commands are then accepted (<CR> refers to the "return" key): <CR> play next portion from each file r<CR> repeat current portion from each file b<CR> back up and play previous portion from each file c<CR> continue playing portions without stopping for commands q<CR> quit</PRE><H2>ESPS PARAMETERS</H2><PRE> The ESPS parameter file processing is the same as that for <EM>mcplay</EM>.</PRE><H2>ESPS HEADERS</H2><PRE> ESPS headers are treated as in <EM>mcplay</EM>.</PRE><H2>OPTIONS</H2><PRE> The flags <STRONG>bcgirwx</STRONG> are passed to the local play program every time that program is invoked. In addition, the following options are supported: <STRONG>-{prsf}</STRONG> <EM>range</EM> Selects the first portion that will be played from each file, with syntax as in <EM>mcplay</EM>. The default is <STRONG>-s</STRONG>0:1. If the part of the range specification after the colon is omitted (giving only the starting point), the defaults are as follows: <STRONG>-p</STRONG><start>:+7999 <STRONG>-r</STRONG><start>:+7999 <STRONG>-s</STRONG><start>:+1 <STRONG>-f</STRONG><start>:+79 These give approximately the same length (1 second) when the sampling frequency is 8000 Hz., but not otherwise. The effect of the <STRONG>-</STRONG> <STRONG>{psrf}</STRONG> option is to select the starting position and length of the portion. This length remains in effect for subsequent portions that are played, while the starting positions of subsequent portions are determined by the <STRONG>-n</STRONG> option. Note that <STRONG>-p</STRONG> and <STRONG>-r</STRONG> are synonyms. <STRONG>-d</STRONG> <EM>delay</EM> If <STRONG>-d</STRONG> is not specified, <EM>sdcomp</EM> passes all the filename arguments to one invocation of the play program each time a portion is played from the files. If <STRONG>-</STRONG> <STRONG>d</STRONG> is specified, then each filename is passed to a separate invocation of the play program, which is followed by a pause of <EM>delay</EM> seconds. (Note that specifying <STRONG>-d0</STRONG> is not equivalent to omitting the option entirely.) <STRONG>-w</STRONG> <EM>width</EM> [100] This option defines the frame width. The width is ignored unless the <STRONG>-f</STRONG> option is also specified. <STRONG>-n</STRONG> <EM>step</EM> Selects the amount by which the starting position is changed from one portion of each file to the next por- tion of each file. If the <EM>step</EM> is less than the por- tion length (determined by <STRONG>-{prsf}</STRONG> ), the portions will overlap. If it is greater than the portion length, the portions played will skip segments of the files. The <EM>step</EM> must be expressed in the same units as the <EM>range</EM>. That is, if <EM>range</EM> is specified with <STRONG>-p</STRONG> or <STRONG>-r</STRONG> (points), the <EM>step</EM> is assumed to be points, etc. The default for <EM>step</EM> equals the length of the initial portion specified by the <STRONG>-{prsf}</STRONG> option.</PRE><H2>FUTURE CHANGES</H2><PRE> The user should be able to change the order in which files are played. There should be an option that causes <EM>sdcomp</EM> to select the order in which files are played and report that order after all of the speech has been played. The user should be able to change the position, portion length, and step size dynamically. The user should be able to specify a separate gain (<STRONG>-</STRONG> <STRONG>g</STRONG>) or shift-value (<STRONG>-b</STRONG>) for each input file.</PRE><H2>SEE ALSO</H2><PRE> <STRONG><A HREF="../man1.html/play.1.html">play(1-ESPS)</A></STRONG>, <STRONG><A HREF="../man5.html/FEA_SD.5.html">FEA_SD(5-ESPS)</A></STRONG></PRE><H2>WARNINGS</H2><PRE></PRE><H2>BUGS</H2><PRE> <EM>A</EM> <EM>range</EM> or <EM>step</EM> value in seconds is restricted to integer values (this reflects a bug in <EM>play</EM> ).</PRE><H2>AUTHOR</H2><PRE> Manual page by John Shore; program by Rodney Johnson</PRE></BODY></HTML>⌨️ 快捷键说明
