This guide will mainly focus on making music via dectalk
I recommend reading this as it is a great general guide for how dectalk works.
The one downside to dectalk imo is you can't have multiple tracks
PART 1 - BASIC FORMATTING
The basic formatting for what I call "TONES" is this.
[:t{ToneInHz} {ToneLength}]
An example of what a song would look like is this
[:t1174 200 :t0 200 :t1046 200 :t932 200 :t880 600 :t0 200 :t880 200 :t0 200 :t932 200 :t0 200 :t783 400 :t0 200 :t783 200 :t880 200 :t932 200 :t1046 200 :t783 200 :t880 200 :t932 200 :t1046 200 :t1046 200 :t0 200 :t1174 200 :t1046 200 :t932 200 :t0 200 :t880 200 :t0 200 :t1174 200 :t0 200 :t1046 200 :t932 200 :t880 600 :t0 200 :t880 200 :t0 200 :t932 200 :t0 200 :t783 400 :t0 200 :t783 200 :t880 200 :t932 200 :t1046 200 :t783 200 :t880 200 :t932 200 :t1046 200 :t1046 200 :t0 200 :t932 200 :t880 200 :t783 600]
Phonemes aren't as hard as you think.
They are formatted like this.
[{phoneme}<{PhonemeLength},{PhonemePitch}>]
An example of what it looks like is this
[diy<200,26>strr<150,28>biy<500,36>ng<300,34>thuh<350> piy<500,33>s]
PART 2 - TONES
Tones are basic.
They only have 2 parts.
The first part is the tone in hz.
The 2nd part is the tone's length.
Since dectalk only has one track what you need to do to play chords is play 3 or more notes really fast, one after another.
An example of this technique being used is this
[:t698 15 :t880 15 :t1046 15 :t698 15 :t880 15 :t1046 15 :t698 15 :t880 15 :t1046 15 :t698 15 :t880 15 :t1046 15 :t698 15 :t880 15 :t1046 15 :t698 15 :t880 15 :t1046 15 :t698 15 :t880 15 :t1046 15 :t698 15 :t880 15 :t1046 15 :t698 15 :t880 15 :t1046 15 :t698 15 :t880 15 :t1046 15 :t698 15 :t880 15 :t1046 15 :t698 15 :t880 15 :t1046 15 :t698 15 :t880 15 :t1046 15 :t698 15 :t880 15 :t1046 15 :t698 15 :t880 15 :t1046 15 :t698 15 :t880 15 :t1046 15 :t698 15 :t880 15 :t1046 15 :t698 15 :t880 15 :t1046 15 :t698 15 :t880 15 :t1046 15 :t698 15 :t880 15 :t1046 15]
A useful resource I recommend for this is dbkai because it has a midi converter (also writing bells for dectalk is nicer then remembering all of the note to hz conversions)
PART 3 - PHONEMES
Phonemes are a bit complex, not nessicarly in the fact that it's difficult to use but there's so many more variables and combinations of them.
An example of this is
[hxiy wuhs ey jhaaliy gurd fehllow]
for the sentence, "he was a jolly good fellow."
A good resource I recommend is this as it has a good list of all of the phonemes you can use.
PART 4 - PHONEME LENGTH
This part is the only easy part about phonemes
The length is in ms
it's formatted like this
[{Phoneme}<{PhonemeLengthInMS}>]
[hxay<100>hxay<100>.hxehlow]
using '.' ',' and '_' will allow the tts to breathe while singing as shown in the example above
PART 5 - TUNING THE VOICE
I recommmend for this portion you use this as it will be important for this section
Literally just add the pitch after the phoneme length like this
[{Phoneme}<{PhonemeLengthInMs},{PhonemePitch}>]
[hxay<200,29>hxay<200,29>.hxeh<200,22>low<200,20>]
