Pull up the recording of your last discovery call and do one thing before you listen to a word of it: scrub through and watch who's got their mouth open. Not what's being said, just who's talking and for how long. Most reps who do this for the first time are shocked. They walk in believing they ran a conversation. The waveform says they ran a monologue with a few interruptions from the buyer.
This isn't a confidence problem or a script problem. It's a math problem, and it's fixable the moment you can see it. A rep who talks 70% of a discovery call isn't failing because their pitch was weak. They're failing because they spent the call filling air that the buyer needed in order to think, hesitate, and say the thing they hadn't planned to say. That thing is usually the only part of the call worth having.
Why sales reps talk too much without noticing
Nobody sits down and decides to dominate a call. It happens for three specific, avoidable reasons.
Silence feels like failure in the moment, even when it's working. A buyer pauses after a question and the rep's instinct reads that pause as dead air, something to be filled before it gets awkward. So the rep jumps back in with a clarification, an example, or a second version of the same question. The buyer was actually thinking. The rep just talked over the thought.
Pitching leaks into discovery. The rep asks a question, gets a partial answer, and hears an opening to explain how the product solves exactly that. It feels helpful. It's premature. Discovery is the only part of the call where the buyer's unfiltered problem is available to you, and every minute spent pitching during discovery is a minute the buyer isn't spent telling you something you didn't already know.
Nervous energy defaults to words. Under pressure, most people manage anxiety by talking, not by going quiet. A rep who's uneasy about a call fills the space instead of sitting in it, because silence on a call you're nervous about feels ten times longer than it actually is.
None of these are talking too much on purpose. They're talking too much by default, and the fix is a deliberate ratio target plus a couple of concrete moves that replace the reflex to fill space.
The target, and the two moves that get you there
Aim for the buyer talking at least 60% of a discovery call, ideally closer to 70%. That's not a vibe, it's checkable: most call recording tools log a rough talk-time split, and if you don't have one, timing three calls against a stopwatch will tell you where you actually stand, which is usually worse than you'd guess.
Two moves get you there without needing to become a different person on the phone.
Ask, then count to three before you say anything else. Silently. In your head. Most reps refill the space around second one, well before the buyer has actually finished forming their answer. Three full seconds feels enormous the first few times. It is also frequently the exact gap where a buyer adds the real detail after the safe one, "it's fine, mostly... actually, the reporting is a mess."
Label the pause instead of filling it. If three seconds of silence genuinely feels wrong on a call, you don't have to fill it with more words. You can name it: "Take your time, I'm just thinking about what you said." That's still your voice in the room, but it hands the floor straight back to the buyer instead of using it to explain your product.
Worked example: the same question, two ratios
Below is a fictional AE, Priya, at a contract management platform called Ledgerfold, on a discovery call with Tom, a fictional operations director at a mid-size logistics company called Haulwright.
High talk-time version:
Priya: So how are contracts getting reviewed today? Are legal and ops both touching them, or is it more centralized?
Tom: It's pretty centralized, legal owns it, but ops flags anything with SLAs attached.
Priya: Got it, that's really common, actually most of the teams we work with have that same split, legal owning the paper and ops watching the SLAs. What we usually see is that flagging process gets slow because it's happening over email, and then things get missed right before renewal. Does that sound familiar?
Tom: Yeah, I mean, sometimes.
Priya asked a real question, got a usable answer, and then buried it under her own explanation of what the answer probably meant. "Sometimes" is Tom disengaging, not confirming. He didn't get to describe his own version of the problem because Priya described it for him, and now the call is following her guess instead of his actual situation.
Low talk-time version:
Priya: So how are contracts getting reviewed today? Are legal and ops both touching them, or is it more centralized?
Tom: It's pretty centralized, legal owns it, but ops flags anything with SLAs attached.
Priya: (three seconds) And how does that flagging happen, practically?
Tom: Honestly it's a mess. It's supposed to be a shared tracker, but half the time ops just emails legal directly and it gets lost in someone's inbox until a renewal is like a week out.
Priya: A week out. What happens when it gets caught that late?
Tom: Last quarter we auto-renewed a contract nobody wanted at the old terms because the flag never made it to legal in time. That was an expensive week.
Same opening question, one extra beat of silence, and Tom volunteered a specific, costly incident that Priya couldn't have guessed at. She said maybe twenty words across the whole exchange. Tom said the thing that actually moves the deal forward: a named, quantifiable failure with a dollar consequence, and she got it by staying quiet enough for him to reach it himself.
Common mistakes and edge cases
Confusing "quiet" with "checked out." A low talk-time ratio doesn't mean sitting there passively. Short, sharp follow-ups, "how often," "what happens then," "who felt that," take almost no time and do most of the work of pulling the real answer out.
Over-correcting into interrogation. Going silent after every single answer without any acknowledgment at all reads as cold, not disciplined. A short "that makes sense" or "okay" before the pause is enough to stay human without reclaiming the floor.
Talkative buyers hiding a bad ratio. Some buyers genuinely monologue, and a rep can end up under 40% talk time by accident while still running a bad call, because they never redirected a rambling answer back toward the specific detail that mattered. Ratio is a useful signal, not a guarantee, on its own.
Treating the ratio as the goal instead of the tool. The number exists to catch the habit of filling space with your own voice. If you hit 65% buyer talk time by asking flat, closed questions that only need one-word answers, you've hit the target and missed the point.
Doing this for the first time on a live call. The three-second pause feels unnatural before it feels normal. Practicing it somewhere lower stakes than a real prospect, so the pause becomes a reflex instead of something you're consciously fighting, makes it far more likely to survive contact with a buyer who's used to reps filling every gap for them.
The next call you're on, don't worry about what you're going to say. Worry about how long you can go after asking a question before you say anything else. That's the whole skill. Everything else on a discovery call, the questions, the pitch, the next steps, works better once the buyer has actually had the room to answer.
