I'm working on an application that requires a modest vocabulary of stored speech for telemetry - typically some electronics jargon, words like "alarm", "battery", "off", "on", and the numbers. In the past I've used the Digitalker chipset, with both vocabulary sets that were available for it, but some of the words I would have liked to have just weren't in the vocabularies, and I don't think I can record my own for it. I don't mind recording and digitizing my own words if I can do it cheaply. The application is an embedded controller that has no bulk storage (i.e., ROM only, no disk) and only needs to have telephone- quality speech. I'd really like something that would speak a whole word or phrase without any significant attention from the control processor - with the Digitalker, you just select the word address and strobe it, and it signals when it's done. Suggestions? MAIL to me and I'll summarize for the group. Brian Kantor UC San Diego brian@ucsd.edu ucsd!brian BRIAN@UCSD

It's an EEPROM capable of sampling and storing sound, with an integrated input filter (anti- aliasing) and output power amp. All you need to get solid state recording is an external mike, speaker, battery, and a few other discretes. The model they have available at the moment stores 16 seconds of sound with a S/N ratio of 40dB and 3400Hz bandwith. What makes this so useful is the integration of I/O and the non-volatile (i.e. no battery backup) storage on the same chip. With the ability to store sounds at specific addresses you can sequence bits of sound or phrases under external control, and you can stack the chips for more time. What makes it most interesting, however, is that they don't use any digitizing circuits--the analog input signal is stored in the EEPROM cell as an analog voltage on the floating gate, allowing a complete sample to be stored in one cell (as opposed to 8 cells in a digital storage scheme for similar resolution). At any rate, the company is ISD and their address is 2841 Junction Ave., Suite 204, San Jose, CA 95134; and the phone number is 800-825-4473. The price for the ISD1016 (described above) is supposed to be about $20, with other products planned. Disclaimer: I have no connection with ISD, not even as a customer- I just thought it was a pretty novel and interesting design. glen rosendale cypress semiconductor gbr@cypress.uucp

One of the devices I "invented" (you know, you think these things up and then find someone beat you to it...) were electronic post-it notes. Save a few seconds of speech in a cheap little device and leave it around for yourself or a friend. A couple of years ago a friend of mine had one that he got from OKI at a trade show. I think it was a keychain, the actual unit a little fatter than a watch. It stored something like 30 seconds of intelligable speech. It had a couple of buttons on it and could save several messages. A neat little toy but I have yet to see one since. jv "Somebody needs to do something--it's just incredibly pathetic that it has to be *us*." -- Jerry Garcia _____ | | Johnathan Vail | n1dxg@tegra.com |Tegra| (508) 663-7435 | N1DXG@448.625-(WorldNet) ----- jv@n1dxg.ampr.org {...sun!sunne ..uunet}!tegra!vail --
