• General
  
  PASTE is the public acoustic analysis system for speech using techniques of E-mail and web.
  You have only to send mail to PASTE with speech file. Then you can browse the visualized results of speech analysis by Internet.
  It is not necessary to install a special software in your computer for the use.
  
  To view an example of the analysis images, please click here.
  If you want to know the system configuration, please read the system page.
  
  Please use the system for speech reading, visualization of speech, language learning and phonetics.
  Let's try speech analysis.

• Usage
  
  1. Record Speech
     
     • Record speech at upper format by PC.
       
     
     
  2. Send E-mail
     
     • Send mail attached speech file to PASTE.
       You can change Analysis mode by input command in subject. Please refer to next table.
       
       

       Analysis command	Analysis mode	Explanation
       lc	Locus of LPC analysis	Analyze whole speech
       sc	LPC section analysis	Analyze 1 frame of speech
       noting(default)	Locus of LPC analysis	Analyze whole speech

       
       In LPC section analysis, you can designate frame of analysis by input option.
       
       

       Option for "sc" command	Explanation
       Integer	Analyze designated frame
       Noting	Analyze max of speech point

       
       If you designate option of sc, please input space between command and option.
       
       We show examples of E-mail subject.
       
       

       E-Mail Subject	Analysis mode
       lc	Analyze whole speech
       sc	Analyze max of speech point
       sc 20	Analyze 20 frame of speech
       Nothing	Analyze whole speech

     
     
  3. Receive E-mail
     
     • When analysis is finished, PASTE system send E-mail for you.
       This mail includes ID required when you watch result of analysis.
       If you have some troubles, please check your mail.
       
     
     
  4. View Result of Analysis
     
     • Please input ID sent from PASTE to under textbox. We suggest copy & paste. Soon, analysis image will appear.
       You can download image to your PC. And, you can watch in 1 week.
       
     
     
     If you can understand to use, let's try speech analysis.

• Viewing Result of analysis
  
  • Please input ID sent from PASTE. We suggest copy and paste for ID input.
    
    There is a bug for section analysis. If your ID is sc35_01234@host.domain, please change to sc_35_01234@host.domain.
    
    If you input ID as "examlc", you can view example image of LPC locus analysis,
    And if you input ID as "examsc", you can view example image of LPC section analysis.
