The Late-Night FM DJ Voice
Use a deep, slow, downward-inflecting voice to project calm authority and trigger trust without triggering defensiveness.
The Late-Night FM DJ Voice is one of three voice tones Voss teaches negotiators, and it is the most powerful for projecting authority. It is deep, soft, slow, and uses a downward inflection that conveys a single message: 'I'm in control.' The voice works through neurological mechanisms: our brains process not just words but the emotional signals carried by tone, triggering involuntary trust or distrust responses.
Voss identifies three negotiator voices: the Late-Night FM DJ Voice (for making points and establishing authority), the Positive/Playful Voice (the default for most interactions), and the Direct/Assertive Voice (almost never appropriate, as it triggers defensiveness). The key insight is that how you say something matters more than what you say. Albert Mehrabian's research suggests only 7% of a message comes from words, while 38% comes from tone of voice and 55% from body language.
The DJ Voice is used selectively for maximum impact. When you inflect downward, you declare rather than ask. When you inflect upward, you invite challenge. Master negotiators choose their inflection deliberately.
- How you say something is far more important than what you say
- A downward inflection projects authority and certainty
- An upward inflection invites challenge and shows uncertainty
- The Positive/Playful voice should be your default (80% of the time)
- The Assertive voice causes defensiveness and should rarely be used
- Smiling while talking on the phone changes your tonal quality and the other person can hear it
- Voice tone works cross-culturally and is never lost in translation
- Practice the Three VoicesRecord yourself using all three voices: (1) Late-Night FM DJ: deep, slow, calm, downward inflection; (2) Positive/Playful: light, encouraging, smiling; (3) Direct/Assertive: firm, clipped, commanding. Listen back and notice the emotional impact of each.Pro tipPractice the DJ voice by reading a passage aloud as if you are narrating a calm nature documentary. The key is slow pace and downward inflection at the end of sentences.
- Default to Positive/PlayfulIn most interactions, use the Positive/Playful voice. Relax, smile (even on the phone), and speak with light, encouraging energy. This puts people in a collaborative frame of mind and increases their mental agility.Pro tipA smile can be heard over the phone. It changes the shape of your vocal tract and produces warmer, more inviting tones.
- Switch to DJ Voice for Key MomentsReserve the Late-Night FM DJ Voice for moments when you need to establish a non-negotiable point, de-escalate tension, or project calm authority. Use it when delivering a mirror, a label, or a statement that is not open for discussion.Pro tipTo practice the downward inflection, say 'We don't do work-for-hire' and drop your pitch on the last word. It should sound like a period, not a question mark.
- Avoid the Assertive VoiceThe Direct/Assertive voice triggers fight-or-flight responses and creates pushback. It signals dominance and provokes either aggressive or passive-aggressive resistance. Use it only as a last resort, and even then, consider a calibrated question instead.WarningIf you are naturally an Assertive negotiating type, you may default to this voice without realizing it. Consciously soften your tone.
During the Chase Manhattan Bank robbery, Voss used his Late-Night FM DJ Voice to take over negotiations from the previous negotiator. Despite the jarring change, his calm 'Joe's gone. You're talking to me now' with downward inflection immediately established his authority. The second hostage-taker, Bobby, dropped his guard within minutes and said 'I trust you.'
Voss first deployed the Late-Night FM DJ Voice during the 1993 Chase Manhattan Bank robbery in Brooklyn. After hours of stalled negotiations, the lieutenant in charge asked Voss to take over the phone. He switched to his deep, slow, reassuring voice and told bank robber Chris Watts: 'Joe's gone. This is Chris. You're talking to me now.' The downward inflection made it a statement, not a question. Despite the abrupt personnel change (against standard protocol), the voice created instant calm and trust. The second hostage-taker, Bobby, eventually said: 'I trust you, Joe' (mistaking Voss for the original negotiator), and surrendered peacefully.
