Dear AUDITORY community,
I am preparing speech stimuli for a perception study, and I wanted to ask whether there are methodological papers or guidelines that describe common practices for processing recorded speech for both single words and full sentences. I have already recorded the
items (in Audacity) and I am overall happy with the quality, but now that I am working through the processing, a few questions keep coming up, such as:
-
how people usually detect onset and offset (automatic vs. manual trimming)
-
typical processing steps after recording (normalization, noise reduction, fade-in/fade-out...)
-
how fade durations are usually chosen (fixed milliseconds vs. percentage of item length)
Stimulus-preparation steps do not seem to be reported in much detail, so I wanted to ask whether there are any recommended methods papers, workflows, or best-practice examples that people rely on.
Any pointers or suggestions would be very much appreciated.
Many thanks in advance!
Katharina
