75-year-old American male voice. Clearly elderly, with a deep, weathered, slightly gravelly voice and subtle rasp. He should immediately sound around 75, not 55 or 60.
Warm, curious, intelligent, and conversational, like an older podcast host speaking naturally with an expert.
VERY IMPORTANT: keep the delivery fluid. Do not add long pauses between sentences. Most lines should connect naturally, with only very short pauses unless the meaning clearly requires one.
Slightly slower than a young speaker, but still engaging and easy to follow. Avoid sounding sleepy, frail, weak, or overly dramatic.
Questions should sound spontaneous and genuinely curious, not read from a script.
Use natural pitch variation and small hesitations occasionally, but never create one-second gaps after every sentence.
Overall: clearly elderly American man, around 75, warm, sharp, slightly raspy, natural, conversational, and smooth-flowing.
You know [sigh], I've been thinking about what you said regarding the data [emphasis] really carefully. It's fascinating, isn't it? [short pause] Tell me, how exactly do you see that playing out over the next decade? I'm [laugh] genuinely curious to hear your take.
