• Plain or HTML or RTF formatted text, image and audio prompts
  to elicit speech in many different ways,
• Unicode text
  to display most of the world's languages,
• XML-formatted recording scripts
  for a flexible organization of recording sessions, including options for automatic recordings and randomized prompt selection,
• Multi-channel audio input
  for synchronous recordings over two and more audio input channels using the built-in or external sound devices,
• Configurable speaker and experimenter screens
  for an uncluttered and appealing graphical interface,
• URL addressing
  to access recording scripts on remote sites and save audio recordings to a server via the Internet,
• Platform independence
  to run the software on any modern computer, from laptop to desktop.

SpeechRecorder was developed at the Bavarian Archive for Speech Signals (BAS) of the Institute of Phonetics and Speech Processing at Ludwig-Maximlians-Universität München.

This program comes with ABSOLUTELY NO WARRANTY.

Requirements:

Most PC's already have JAVA installed. Otherwise you can download JAVA here.

The Java Webstart launch starts Speechrecorder only under appropriate versions.

Limitations:

JavaSound with Mac OS X is currently not able to record from USB audio sound cards!

The AJS and ASIO versions are only running with Windows!

Installation

The recommended way to install and run the program is using Java Webstart technology. Just klick on the buttons below to install and start Speechrecorder. Under Windows it will install the software, a desktop icon and an entry in the start menu in a folder 'BAS' to launch Speechrecorder.

The application is self signed, so you will get a security warning, that the signature of the application could not be verified.
SpeechRecorder cannot run inside the security constraints of the Java sandbox, because audio recording would not be possible.

The ASIO versions are required for some multichannel soundcards under Windows

The AJS (alternative JaavSound) versions are required for some multichannel soundcards under Windows or recording problems with Windows 7 64-bit.
