10.0pt;font-family:Arial;color:navy'>Thank you Ulysses and Raymond for providing
an explanation of how to generate tones with the tone command. James, To make Dectalk
sing you need to use phoneems, pitches for notes and time values. Phoneme-based
singing is different from tone generation because different numbers are used. That
and the use of phonemes to represent sounds. The pitches for singing range from
1 (low c) to 37, or maybe 38 I don't quite remember. Anyway, 13 is middle C, 15
is D, 17 E, etc.<o:p></o:p></span></font></p>

<div>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Hi,</span></font><o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>It's been a ridiculously long time since I popped in here,
but I've been fighting with e-mail settings forever and got tired of dealing
with it. Now I finally got it sorted.</span></font><o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>The numbers used in Dectalk's tone command represent note
frequencies. Basically, the number represents how many times the wave travels
up and down in one second. The higher the frequency, the higher the pitch of
the tone.</span></font><o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Unfortunately, all this isn't very useful when it
comes to musical synthesizers. So there are several methods to convert
musical notes to frequency.</span></font><o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>One thing that holds true though, is that the A above
middle C has a frequency of 440 hertz, so you'd use 440 in Dectalk's tone
command to generate that A. If you wanted the octave above, you'd use 880, for
the octave above that, you'd use 1760, etc. And for the octaves below, you'd
use 220, 110, etc. just doubling or halving the frequency depending on which
direction you wanted to go. "Fine," you say, "What about other
notes?"</span></font><o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>The easiest way to get other notes is to go online and try
searching for a frequency to musical notes reference table. Many exist, with
varrying degrees of accuracy. I wouldn't spend too much time nit picking on
accuracy at least for Dectalk use, because I think Dectalk can only do whole
numbers anyway. One or two values off the mark isn't going to make too much of
an audible difference. The main thing to check for is that there is an A 440 on
the chart, and every A above that is doubling, and every A below is half like
I said above.</span></font><o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Now, the really dirty approach that you can do if you don't
feel like looking at a chart but instead want to do your own math. Why you
would use this approach over a simple chart is beyond me unless you're
genuinely interested in the maths, but here goes anyway.</span></font><o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>If you want to calculate other frequencies for other notes
yourself, you can multiply a bass frequency, such as 440, by the 12th root of
two. I'm not sure what that is but I did have it written down before. I've done
a quick calculation and if you multiply by 1.0594631, that is pretty close. So,
440 multiplied by 1.0594631 is about 466, so that 466 in Dectalk's tone command
would get you A sharp.</span></font><o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Now, that multiplication figure I gave above isn't totally
accurate; the A an octave above, as I said, should be at 880 hertz exactly, but
if you do the multiplication as suggested above, you'll get something like
880.00006. Which won't make an audible difference to even the most trained
ear. Even if you'd come up with 881, I doubt most people would notice, even if
you'd played 440 right before.</span></font><o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>If you keep multiplying it out to get higher and higher
using the figure I gave, you're not going to run into a huge margin of error
until you get into ultrasonics, and dectalk can only go up to 5512 HZ. Which is
just a step up from telephony. In other words it's not high enough to pose a
problem here. That said, however, if you actually multiply by the 12th route of
2 properly, you'll avoid that margin of error, or at the very least, keep it
negligible.</span></font><o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I hope all of this has helped. Don't let the complicated
multiplication by the 12th root of 2 and the like overwhelm you. I just put it
here to show how to do it scientifically if you were interested to take that
route. Like I said, just looking them up on a reference table really should be
all you have to do to get satisfactory results.</span></font><o:p></o:p></p>
