Are there any simple howtos anywhere which describes the process in as simple terms as possible? Without knowing the cool toolkits du jour.

Something like: - Download these texts - Record in WAV at least 48 kHz - Record each line in a separate file. - Do 3 takes of each line: flat, happy, despair

Maybe even a minimal set and a full set depending on how much effort you are willing to put in.

A plain description on how to capture a raw base which within reason and technology could be used as a baseline for the most common toolkits.

I have myself looked into this (for fun) but I felt I needed a very good understanding of the toolkits before even starting to feed in data. And for my admittedly unimportant use it seemed a huge investment to create a corpus I was not even confident would work. I ended up taking the low road and used an existing voice.

Not really, this is the only thing I know of in terms of collection: https://www.isca-speech.org/archive/Interspeech_2018/pdfs/24... Usually you're basing your recipe off of those for existing datasets (TIMIT, WSJ, LibriSpeech, etc).

For recording training audio:

The recorder works with Python 3.6.10. Need to pip install webrtcvad also.

Is Morgan Freeman the most used celebrity?

A ranking of used voices would be fascinating. Especially broken down by user statistics.

I'd go for Stephen Hawking, myself.

(Not using his voice synth, reconstructed using ML, because it should sound more natural that way ;-)

I recall that the "say" program on the SGI from the mid 90's was approximately Hawking's voice. Hawking gave his speech for the Whitehouse Millennium Lecture at SGI also, and while I wasn't able to attend I found the transcript of it and fed it in there... there were some jokes that he had that only really came through with the intonation and pacing of a voice synth -- its the ultimate dead pan voice.

And his voice was his - even with the American accent.

Somewhere, I recall a NOVA(?) program from the mid 80s where it showed him using the speech synthesizer and the thing that he said with it that still sticks in my mind is the "please excuse my American accent". In later years he was given the opportunity to upgrade it to a more natural sounding voice - but that voice was his.

Near the end of his life, his original voice computer started to fall apart. He managed to get in touch with the people who wrote the software, who started a mad scramble to find source, and ultimately ended up emulating the whole setup on a Pi.

Hawking’s original voice synth was the default sound of the DECtalk hardware speech synth.

It would not surprise me if SGI’s software implementation were similar to the he most popular hardware of the 1980s.

Unfortunately dad passed 21 years ago. But the options now are much better. Just projecting my past experiences on the obvious Delta.
