They (we) are writing a TextToSpeech object. I am writing an animation tool, the user will enter a line of text, the computer will display an animated talking face on the screen and will also say what you typed in. Hows that for interesting vince demarco demarco@cpsc.ucalgary.ca --------- From: Mark Gallagher Date: Tue, 28 May 91 15:37:01 BST To: jiro@shaman.com Subject: NeXT DSP Dear 'jiro', I read you letter on comp.dsp and wondered if you had posted it to comp.sys.next. You'll probably be snowed under with replies. Here at the University of Hull (UK), in the Comms Group, Dept. Electr. Eng., we have just taken delivery of a few NeXTs which we will be using to attempt to port across some of the research going on here: In particular - pseudo-noise using Trajectory derived sequences modems matched-filter detection systems fractal noise comms systems If you want any more info, eg paper refs just give me a buzz The NeXT will be the staple for the investigation into Radio Systems architecture and more of the machines will be ordered. As for the DSPApp Kit you talked about, there is a need for such a system, but you can use the LSI HyperSignal Program on the PC to generate code. However, if you are a DSP-jockey, you will realise that most code is `hand-crafted' for real-time speed. So combining this with the NeXT will hopefully produce some really excellent research (and demos). Cheers, Mark Gallagher Hull-Warwick Communications Research Group Dept.

The DSP hardware would be used by those library calls at run time. But the 56000 is integer-only. I wish NeXT had used the 96000 in their latest machines since that chip has floating point support. A similar preprocessor could have been used for C. NeXTime. ---------- Hope this helps people. Please send replies on your projects to comp.sys.next and comp.dsp, I'd really like to sponsor a discussion on the net about different uses of the DSP. What is the Shaman Group doing? We're currently investigating its uses as a general purpose image processor, trying to use it for some special effects, etc. - Jiro Nakamura jiro@shaman.com -- Jiro Nakamura jiro@shaman.com The Shaman Group (607) 256-5125 VOICE "Bring your dead, dying shamans here!"
