Query:	Dear linguists, I'd like to compare digital speech samples collected from different sources, including online radio and samples digitized by myself from analogical sources. I'm specially interested in fundamental frequency and formant position, as well as time-related aspects of segments (specifically VOT and vowel duration). My questions are the following: What features of the speech signal (and in what ways) may be affected by the format of speech samples (MP3, VAV, stream audio...)? Are the results of spectrographic analysis of samples with different file formats and qualities comparable? Is there any relevant bibliography available on this issue? Thanks a lot in advance. I'll post a summary. Mario Cal Varela University of Santiago de Compostela, Spain.
