Voice Coaching: How AI Helped Me Stop Saying "Um"

"Um, I, uh, just want to say that I'm really excited, um, to be here." Sound familiar? If you've ever found yourself stumbling through sentences in an interview, punctuating your thoughts with endless "ums," you're not alone. It's incredibly frustrating to feel your confidence ebb away with each filler word, especially when you know you have the skills and experience to shine. But what if I told you there's a way to break this habit and transform your interview performance?

The Problem Everyone Ignores

For many job seekers, nervous habits like saying "um" can seem like a minor issue. But research shows it can have a significant impact. According to CareerBuilder, 65% of job seekers reported that filler words negatively impacted their interview performance. It's not just about the words you choose—it's about how you deliver them. A staggering 70% of communication is non-verbal, and vocal delivery plays a critical role in job interviews (Harvard Business Review, 2025). This means even if your resume is perfect, your delivery might undermine your message. If you're nodding along thinking, "Yeah, that's me," then keep reading for an "aha" moment you might not expect.

Why The typical approach Doesn't Work

You've probably heard the usual advice: "Just practice more," they say. While practice is essential, it often doesn't address the root cause of filler words. Why? Because practicing in front of a mirror or with friends doesn't replicate the pressure and nerves of a real interview. When the stakes are high, those filler words can slip out unconsciously. "I practice, but when I'm in the moment, those filler words just slip out. It's embarrassing!" Sound familiar? The real solution lies in understanding and restructuring your vocal habits—and that's where AI comes in.

The 3 Things That Actually Work

AI voice coaching is not just a futuristic concept; it's a practical tool that's reshaping how we prepare for interviews. Here are three steps that helped me—and can help you—reduce those pesky filler words.

Step 1: Identify Patterns with AI

The first step is awareness. AI tools can analyze your speech patterns and identify when and why you're using filler words. By recording your practice sessions, AI can pinpoint specific moments when you're likely to say "um." This data-driven approach offers insights you might not notice yourself, like whether you're using fillers when transitioning between thoughts or when you're unsure of what to say next.

Example: Use an AI tool like an AI voice coach to record your mock interviews. Review the analysis to identify key patterns—maybe you find that "um" creeps in most during technical questions.

Step 2: Replace Fillers with Pauses

Once you've identified your triggers, it's time to replace those fillers. Instead of "um," use a strategic pause. This not only gives you a moment to collect your thoughts but also makes you appear more confident and in control.

Example: During practice, consciously pause where you would typically say "um." Record these sessions again with AI, and evaluate the difference in your delivery. The AI can provide feedback on whether your pauses are natural or need adjustment.

Step 3: Reinforce with Real-Time Feedback

One of the most effective ways to cement these changes is through real-time feedback during practice. Some AI tools offer live feedback, alerting you when a filler is about to slip out. This immediate notification helps you correct course instantly.

Example: During a session, your AI tool may highlight when you're on the verge of using a filler, allowing you to pause instead. Over time, this real-time correction becomes second nature, and you'll find yourself pausing naturally in actual interviews.

Common Mistakes to Avoid

Even with AI, there are pitfalls to watch out for:

• Over-reliance on Tools: While AI is powerful, remember it's a tool, not a crutch. Balance its use with genuine practice.
• Ignoring Non-Verbal Cues: Don't focus solely on words; your body language and tone are equally important.
• Skipping Real-World Practice: Simulated environments are great, but nothing beats real-world practice. Attend mock interviews or use networking events to test your skills.

Your Next Step

Breaking the "um" habit is entirely within your reach. Start by incorporating AI into your practice routine and watch your confidence grow as those fillers fade away.
