Recording Protocol

In case of WebCommand it would have been too costly to create a separate recording protocol. The recording protocol for WebCommand is reduced to a table with one line per recording; general conditions are part of the documentation. The following list of minimal requirements for the recording protocol as given in section contains a + if the content is given (optionally followed by a citation from the documentation) or a - if the content is not given.

Session ID	+ SES + 4 digit number set automatically
Speaker ID	+ 4 digit number set automatically
Date of recording	+
Environmental conditions	+ Room Acoustics: ``The acoustical environment of both rooms is quiet office environment.'' + Sources of Noise/Background Noise: ``There is only one computer (Mac desktop mounted in front of the speaker). No other noise sources.'' + Cross Talk: ``No other noise sources.''
Technical recording conditions	+ (see section , part `Recording situation')
Microphones	+ Head set: Beyerdynamik NEM 192, left channel; Web-pad mic: Beyerdynamik MCE 10, right channel
Recording device	+ The signal of the microphones is amplified by a Beyerdynamik MV 100 amplifier: headset mic + 20 dB, web-pad mic + 20 dB and then connected to the standard Mic input of the recording Mac.
Technical specifications of recorded signals	+ Sampling rate: 22050 Hz; Bits per sample: 16; Length per prompt: 5.7 sec
Placement and distance to microphone(s)	+ The speaker wears a ear-free headset Beyerdynamik NEM 192; the second mic is a Beyerdynamik MCE 10 mounted on the upper left corner of a dummy laptop case that the user holds with both hands on his/her lap.
