In this episode of The Upgrade by Lifehacker, vocal and dialect coach Denise Woods, whose two-decade career includes working with actors such as Will Smith, Halle Berry, Jessica Chastain and Mahershala Ali, walks listeners through the often-overlooked elements of speech: how filler words like “um”, “ah” and “like” dilute your impact; how breath control, articulation and pacing help you convey authority and authenticity; and how uncovering your “voiceprint” – the combination of tone, rhythm and personal style – can transform how you’re received.
Denise explores why many of us default to weak speech habits, how to unlearn them, and practical exercises one can immediately start to strengthen their presence in speaking contexts. Denise also details how mindset plays into voice: when you believe what you say, your voice follows.
Whether you’re presenting in a meeting, recording a podcast, leading a workshop or simply want to feel more confident when speaking your truth, this episode offers actionable tools and fascinating insight from a pro who works behind the scenes in Hollywood but whose advice applies broadly.
