I remember at the NeXT computer demo in Toronto the ability to record
speech, see its spectrum represented graphically, and modify it. Roy F.

Try the NeXt machine, which comes with a built-in
wave-form analyzer.

Also, if I remember correctly there has been some work done
at Yale (Linguistics) using DOS.

Computer-assisted spectrographic speech analysis is indeed
possible on the Macintosh. However, without a fairly massive
investment, it will not be in real-time.

For around US$140 street price, one can buy a MacRecorder 8-
bit A/D device that plugs into any Macintosh. The program
that comes with the device makes very pretty spectrograms,
but does not permit manual scoring directly from the
spectrograms.

To do manual scoring in a much more powerful environment,
people can buy Signalyze for US$250. The program reads
MacRecorder files (as well as MacAdios, sound resource and
ASCII files), and it can save numeric values directly from
points in the spectrogram where the user clicked. I happen to
be the author of the program, and I'll gladly send more
detailed information about it to whoever requests it.

MacRecorder and SoundEdit will provide a display of input speech, and has some
tools for mamnipulating the display. The basic design of this combination,
however, is for easy and inexpensive recording of sound, not analysis. Lish
Huggins at Dartmouth has a hardware/software package "MacScope" which will
turn the Mac into a very sophisticated oscilloscope with a battery of analysis
tools; microphone input is one of the standard modes supported. This program
is the recipient of the EDUCOM/NCRIPTAL award for best physics software, 1989.
