My "new" EP still doesn't work correctly with the Speakeasy. It sounds but gives unintelligible speak.... I have revised the connector and the EDGE contacts and they seem good. On Monday I will replace the 74LS273 chip involved, because I think that some bits on the port are stuck on 0 or 1.
I left my "old" EP at work, so I can't compare the real thing with Geco's voice editor also until Monday.
Meanwhile I have found a better way to compare the real sound with the one given by Geco's editor, because the little program gives strange voices, very unrealistic samples from the original SP0256-AL2 sounds.
This time it is a
web page that returns the translation of the input phrase to the output allophones string, and also an OGG file(similar to MP3 but without loss of information) with the output sound.
For me the comparison of the two sounds, Geco's voice editor against the web page results, is very promising, they are very similar, but 1/2 slower on the EP. This is not an error, only that the SP0256-AL2 can be used with different oscillators. I think I understand much better the slower EP rhythm.
The good point is that the web page returns the string of allophones by their name, not by their place in the list, exactly like on Geco's voice editor, so it can give a direct introduction of the data. The only difference is how Geco names the pauses, 20, 30, 50, 100 and 200, while the web page returns PA1, PA2, PA3, PA4 and PA5, like on the given SP0256-AL2 allophones list. Not a big problem after some use.
