In phonetics, machines can just help us to consolidate our perceptual findings. We cannot always depend on experimental findings. It is unfortunate that, these days phoneticians rely solely on experimental evidence and they ignore other perceptual evidence. In fact many phoneticians these days do not know basic phonetic measures like Cardinal Vowels etc. When I asked the late Peter Ladefoged: “What do your students in American universities use if they want to refer to different vowel qualities in two or more regional dialects?” His answer was” “They compare formants, plotting on vowel diagrams!”
