Hi,
I recently experimented with an LM386 as an amplifier on the speech adapter I did a while back and there was no real improvement to the output. The existing circuit with the values I have used seems to be fine over the headphone output and acceptable over a speaker. I'm therefore building two units for testing (Well, two units if I can get another chip, I only have two at the moment).
Anyone interested?

Re: Psion Organiser II Speech Adapter
I'm trying to buy more speech chips, but as they are now £16 each, I don't really want to order too many and have them left over. I have one person interested in an adapter, anyone else out there fancy one?
I'm not sure exactly how much one would be, but around the £50 mark is probably right, given the rise in price of the speech chip. I have five new revision PCBs, three of which I've built, but I only have two chips. If no-one else is interested then I'll not build any more, although it probably makes sense to build up the five PCBs I have. These units do work with speakers but are best when attached to headphones or an amplifier as the power supply of the Psion doesn't seem to be quite up to supplying the amplifier.

Re: Psion Organiser II Speech Adapter
That’s fantastic and interesting about potential different allophones/samples - DECtalk (made famous by Stephen Hawking) would be a good one.

Re: Psion Organiser II Speech Adapter
Hi Everyone
I was fortunate enough to borrow an original speech synthesiser from Dave Carrick an enthusiastic member of Boris Cornet's Organiser 2 forum (2010 remnants (here) notice Boris launched Psi2Win build 303 October 15th 2010). I had a great time fiddling with it and created a podcast where it introduces itself. I think I posted a copy on the old forum. Anyway I've attached a ZIP here for those interested..
Sincerely
Martin

Re: Psion Organiser II Speech Adapter
Thanks for the offer. I have one SP0256 but with the new replacement module I don't need them any more, thankfully.Bumblemittens wrote: ↑Sun Sep 17, 2023 7:02 pmHi Andrew,amenjet wrote: ↑Sun Apr 02, 2023 8:45 am Hi,
