The Voice AI Trap: Why Your Customers Are Hating It (and How to Escape)

We all envisioned voice-based AI assistants as the ultimate customer service shortcut, right? A smooth, instant connection between your business and the people who matter most. Our Conversation Design expert, Parus Sheopuri, sums up the potential: 'Unlike traditional IVR systems, modern voice bots leverage NLP and AI to understand and respond dynamically and intuitively. They can play a crucial role in enhancing accessibility, reducing wait times, providing personalized assistance, and achieving greater cost efficiency – that's the idea, anyway.'

Wondering why companies are jumping on the voice AI bandwagon? See what’s really driving the hype (and the ROI) in this article.

But let's be honest, for many customers (and businesses), the reality is more like pulling teeth to get a simple answer. So, what's going wrong? Why isn't this tech delivering on its promises? We talked to Petra Gal, our Conversation Designer, to cut through the hype, expose the common mistakes holding everyone back, and lay out the practical steps to finally make voice AI work for you.

The Voice AI Wake-Up Call: Stop Believing These Myths

Myth 1: 'Voice AI is just a cheap replacement for human agents.'

• Petra: "Think you can just swap out humans for bots and save a buck? Wrong. When cost-cutting drives implementation, the goal shifts from improving user experience to simply replacing human agents. This turns voice assistants into obstacles, not helpful tools. You end up with barriers between users and the support they need. And don't forget, voice is fundamentally different from other interfaces, including chat. A use case that works well in one format may fail in another. You need a team with real experience in voice design, and the right use case."

• Reality: Voice AI should enhance, not replace, human interaction and requires specialized design.

Myth 2: 'NLU training? We'll get to it later.'

• Petra: "Later? That's a recipe for disaster. Many businesses roll out voice assistants without dedicating enough time to training the NLU component. As a result, these systems frequently misinterpret user intents—especially when dealing with industry-specific terms, diverse accents, or background noise. This leads to user frustration and, ultimately, abandonment of the technology. You are wasting your investment if you skip this step."

• Reality: Robust NLU training is essential for accurate intent recognition and user satisfaction.

Myth 3: 'Voice AI is a one-and-done project.'

• Petra: "If you think you can set it and forget it, think again. Voice assistant isn't a one-time project. It's an evolving product. Without regular analysis of user interactions and satisfaction metrics, voice assistants quickly become outdated and ineffective as user expectations change. You need to keep up with the times."

• Reality: Continuous optimization and adaptation are crucial for long-term voice AI success.

Voice AI: Let's Get Real About What Actually Works

Q: "How do we keep voice interactions concise and user-friendly?"

Petra: "In voice-based customer service, brevity is key. Unlike text, users can't easily revisit spoken data. Responses should be brief, ideally limited to three sentences, to avoid overwhelming users with information they can't easily process."

Q: "What's the secret to making voice interfaces sound natural?"

Petra: "When designing for voice interfaces, it's important to 'write for the ear.' Spoken language is inherently different from written language; it's typically more informal, and contractions are expected. Avoid utilizing complicated vocabulary that is more common in writing. 

Even with the advanced capabilities of LLMs, it's crucial to structure answers in a way that aligns with spoken communication norms. This includes being direct and using a friendly, engaging tone that matches the brand's voice. Additionally, the AI should be capable of seamlessly transitioning to a human agent when necessary, especially for complex or sensitive issues."

Q: "How do we add human-like conversational flow?"

Petra: “Use conversational markers. As Cathy Pearl emphasizes, all systems, even formal ones, benefit from conversational markers that match the bot’s personality. Users know they're talking to a machine but still appreciate these conversational basics. 

Conversational markers play a vital role in voice interactions. We use acknowledgments at the start of bot responses to signal that the system has understood the user. They can express emotions like surprise, concern, or simple recognition. 

Common examples include: 

• Positive: great, excellent, good, super, wow, wonderful, nice, perfect, good job. 

• Neutral: got it, Ok, alright, sure, gotcha, sure thing, certainly, on it, thanks. 

• Negative: sorry, hmm, I see, I understand, I hear you. 

It's important to use conversational markers that are appropriate for the context. For example, avoid using affirmative phrases like 'Sure' or 'Got it' if the user has declined an offer. Instead, depending on your bot persona, 'Alright then', 'No problem', or 'No worries' could be more suitable. 

Discourse markers, unlike acknowledgments, are used throughout a conversation to help guide users and manage their expectations. 

Here are some effective types: 

• Sequence markers: first, second, next, finally, lastly, for starters, to begin with, to start, halfway there, almost done. 

• Transitional markers: now, by the way. 

• Result markers: therefore, so, as a result, hence, consequently. 

• Other markers like: also, actually, anyway, otherwise, in that case, furthermore, in addition, alternatively. 

By choosing the right markers, you can enhance the flow and clarity of conversations, which makes them engaging and easy to follow. However, it's important to vary your conversational markers throughout the conversation. Repeatedly using the same marker can make your system sound more robotic instead of less.”

Q: "How do we ensure clear communication in voice interactions?"

Petra: "Because voice assistants can't use non-verbal cues, there's no better way to indicate that it's the user's turn to respond than by asking a question. Ideally, you should place a question at the end of the prompt to avoid misunderstandings and interruptions.

To make voice interactions clearer, ask for information one prompt at a time. This method improves not only how well the system understands users but also how well users remember what the system asked. For example, ask for the date first and then the time. However, be ready to handle users who might give multiple details at once."

Q: "What's the best way to structure information for voice prompts?"

Petra: "Sociolinguist Gail Jefferson's rule of three tells us that people naturally favor information grouped in threes. Given the limits of human short-term memory and the transient nature of the medium, this rule is particularly useful for voice interfaces. You can apply it to conversational menus and lists, where it's recommended to start with the top three or four items and then offer additional choices. 

For conversational menus, start with the three most important options. For example, the bot could say, 'I can help with booking flights, finding hotels, renting cars, and more.' This shows key services and hints at other options with phrases like 'and more' or 'something else'. 

When presenting lists, begin with the top three or four items. For example, 'Here are some top-rated options: Italian Bistro, Sushi House, and Tex-Mex Grill.' Then, ask something like, 'Would you like to hear more?' to offer additional choices."

Don’t just build voice tech for the sake of it. Here’s how to make sure your investment actually solves problems.
