A natural American male voice, around 35 to 45 years old.
He should sound like a real American man speaking naturally, not like a professional voice actor performing a script.
Medium pitch and medium vocal depth. Masculine, warm, relaxed, and conversational. Not deep, not gravelly, not overly polished, and not youthful.
The delivery should feel like someone calmly telling another person a serious story. Natural sentence rhythm, natural pauses, subtle changes in emphasis, pauses, and slight variation in energy from sentence to sentence.
Speak at a comfortable conversational pace. Do not rush, but do not deliberately slow down either.
Avoid the typical AI narrator sound: perfectly even pacing, identical sentence endings, exaggerated pronunciation, dramatic pauses, forced seriousness, artificial bass, theatrical delivery, or a “movie trailer” voice.
He should sound intelligent and composed, but human first. The emotion should be subtle and natural. Serious when discussing disturbing details
The details of what happened next... [pause] they're not easy to recount. [pause] There was a profound silence that settled over everything, [pause] as if the world itself was holding its breath. [pause] I remember the chill in the air, [emphasis] even though it was a warm day. [pause] It's those small, [emphasis] incongruous things that often stick with you the most.
