Known issues

The following list contains some of the known problems of SpeechRecorder. If you find further bugs and errors, please contact draxler@phonetik.uni-muenchen.de.

• When recording with a laptop please disconnect the power adaptor and record using the battery only. External power adaptors may interfere with the audio signal, causing strong distortions. The effect may vary with the brand and type of laptop.
• If you want to use an external XML editor to edit the recording script:
  • Windows: Windows 7 Standard Editor, jEdit (jedit.sourceforge.net) or Atom Editor(atom.io)
  • Mac: we recommend to use the free editor TextWrangler (www.barebones.com) which allows you to import and export content in many encodings.
  • Linux: vim,gedit,jedit,Atom,...
• The following attributes are defined in the recording script DTD, but have not yet been implemented in SpeechRecorder:
  • mimetype and src attributes for the <recinstructions> element are ignored.
  • Silence detection to stop a recording is not yet implemented.
  • Recording/prompting video is not yet implemented.
• The directory name into which the audio files are saved is named after the speaker number in the speaker database. Currently, this number is not visible in the speaker database.
• Attribute values for itemcode may be arbitrary strings, and the value becomes part of the audio file name. This may cause problems if the string contains characters that have a special meaning for the file system, e.g. ”/”, ”:”, ”;” etc. It is thus recommended to use only the characters a-z, A-Z, _ and 0-9 for the itemcode attribute.
