Step Two:
Input your Hex Data for the SC-01-A in this form:
0f262d2a2b2f191f3e02011f1f3c2912210b2b35372d32310d0621293e1f253c292a103e1f0b0d3832231f150029123a3e
Inflection Bit 1
Inflection Bit 2
Clock Rate:
720000 Hz (300000Hz to 1100000Hz acceptable range)

Step Three:
Click and wait for the stream to hit your player. This can take 12 seconds or longer.

** Programming Notes **
** Inflection Bits:
Bits 7 and 6 are "inflection" bits as per the spec sheet; bits 5-0 are phoneme payload. Checking one or both of the inflection bits buttons in this form forces every byte in the spoken phrase to 01, 10, or 11 (00 is the default). You can program each individual phoneme to include its own inflection bits, but its a REAL pain on this form. You'll have to manually code EACH phoneme to include the inflection you want.
For example, in the code example below, the standard, non-inflected coding of "Hello World is:
1b0223182335373e2d3a181e3e
If you want to code the word "Hello" with Inflection Bit 1 (bit 6), you'll have to set bit 6 in EACH PHONEME of that word to 1:
5b4263586375773e2d3a181e3e
** Terminator for Each Phrase:
For some reason, the SC-01-A does not pronounce the end of phrases properly unless you put a 3E at the end. You can see the 3E at the end of all the examples above. Also, use 3E to separate words from one another within your phrase.
** SC-01-A Clock Source:
In this CGI experiment, the SC-01-A is clocked externally by an AD9833 Direct Digital Synthesis IC. The form textarea for the clock speed (in Hz) actually sets the AD9833 to the frequency you specify. The SC-01-A spec sheet standard frequency is 720kHz, so that's why it is set to 720000Hz in that form section. The form accepts 300000Hz through 1100000Hz. Entries outside these bounds are rewritten to be in these bounds. Goofy bros will try inputting text or other special characters in this field. Try it for goofular results!
** Noise and Hum on the Audio Output:
The output of the SC-01-A is nasty looking analog, and the circuit in this CGI project's hardware is directly from the Votrax spec sheet. It is improved over the previous CGI experiment, but the SC-01-A output to the computer microphone/line input is still very noisy, even after improvement. Using the AD9833 as a clock source helped this issue, as it eliminated the RC oscillator and its susceptibility to instability. I've tried a million bypass capacitors, copper metal shielding, low-pass and bandpass filters, unbalanced-to-balanced audio conversion, but it all just distorts the output without improvement. So we're just going to stick with the good old spec sheet output circuit.

Here are some examples. You can either copy and paste into the textarea above then click SUBMIT, or simply click the appropriate radio button to send the example to the engine directly. The radio buttons honor the I1, I2, and CLOCK fields at the top of this page. If you copy/paste, be sure to copy the hexadecimal strings and not the quoted ASCII text. You can put regular ASCII into the form if you really want to but you'll hear gibberish as the output. Please feel free to send me your phrases (including your SC-01-A code) and I'll include them on this page.
