The only exceptions I can think of are the obvious: UTAU, VOCALOID, A/E, Chip Speech, Cevio, moresampler (though this is an engine for UTAU, not it's own full program with UI, etc.), Revivos, and maybe sharpkey - time will tell for this last one (so long as it keeps getting updates and adding features). Many start off with less than stellar quality compared to their established competition and eventually fade into obscurity.

Every other attempt at a synth that has come around thus far has never gotten past working alpha/beta stage (either due to lack of funds, skill, interest, time, or all of the above). creating a synth requires time, effort, and professional training - these are professional tools, not toys for weebs who want to indulge their 'famous vocasynth desu!' fantasies. You could even use total synthesis (not use samples), which would probably sound really robotic but could have potential for FX and such.įirst thing's first. Of course, that's just how you would construct an Utau-like vocal synthesizer, I'm sure there are other ways to do things. If you know anyone who's ever programmed a software synthesizer or a VST plugin before, they would be a huge help since they've worked with audio before. Getting acceptable results will be the big battle for sure. I'm sure you could just use an audio SDK of some sort to implement the above, but chances are it will sound horrible.

Do all the above smoothly and effectively.

This is done by wavtool in Utau, and you need to overlap the samples otherwise you'll end up with choppyness.

Blend all those samples together smoothly.

The maths behind this one are above my head, but it essentially keeps away the 'chipmunk effect'. You also have to incorporate pitchbends here. To do this, you need to figure out the mean pitch of the original sample to work off of. Trim the sample, according to whatever oto.ini alternative you conceive.If you still insist on making a new engine, here's what you'll have to do: But if you know what you're doing (or don't mind doing copious amounts of learning), modifying one of the open-source WORLD based resamplers (w4u, the efg series) could be a possibility. I second the fact that creating an engine on your own is not for the faint of heart - better have a dedicated team of pros to do this one.
