Six candidates reading the same thing. Listen on your phone if you can — that's where members will hear it.
Sulafat
warmfemaleThe closest to a friend at the kitchen table.
Gacrux
maturefemaleOlder-sounding. Speaks to your members as a peer rather than to them.
Vindemiatrix
gentlefemaleSoftest of the six. Calm, unhurried.
Achird
friendlymaleApproachable male voice — the natural fit if the “I” should read as you.
Charon
informativemaleMore authoritative. Might suit the research backgrounders better than the recipes.
Umbriel
easy-goingmaleRelaxed and conversational.
You could use two. A warmer voice for the recipes and a steadier one for the research backgrounders is a reasonable split — it costs nothing extra.
These are WAV files, ~650KB each. The real build would ship smaller MP3s; these are raw so you're judging the voice, not the compression.
Nothing is committed. Picking one is a one-line change, and re-generating all 26 clips takes a couple of minutes.
