What's a good voice synthetizer to make realistic audios?

would that even work with synthesized text?

I dunno, I remember google having some realistic voice synthetizer that sounded like a real woman.

For natural-sounding hypnosis, you would need a synthesizer that gives you full control over intonation and duration.

I once used a tool for a linguistics class that could do that (I'll see if I can find it), but you had to add pitch changes and duration to every syllable manually. That's a LOT of work.

Hypnotists also vary the timbre of their voice (by whispering, etc.), which is very hard to emulate with text-to-speech synthesis.

For what it's worth: every synthesized hypno script I've heard so far sounded terrible.

Found it. The software is called Mbrola, and it's way too involved for what you want to do.

Realistically, these are your options:

1. Have a browser extension, Android or iOS device read the text aloud, and record it from the headphone output. Easy, but very little control.

> Finetune Android voice: http://www.androidauthority.com/google-text-to-speech-engine-659528/

2. Install MARY or Festival. These give you much more control, but will probably only sound good if you spend time tweaking them, which gets pretty technical. They both have an online demo:

> Festival: http://www.cstr.ed.ac.uk/projects/festival/morevoices.html

3. Feed the text line by line into the online demo of a commercial text-to-speech product, and painstakingly record it. There are dozens of these, and many of them sound better than the free alternatives, but the full product is always unaffordable.
