Because when technology meets Norwegian customers, dialects, GDPR requirements, and old CRM systems, many solutions collapse like a cheap camping chair.
So how do you avoid being fooled by flashy demos and buzzwords? You use this checklist:
The three secret weapons (no one tells you about)
Behind every good voice agent, there are three things:
- Prompting – The manuscript that governs how the AI behaves. (Without this: conversations that completely derail – and customers giving up.)
- Labeling – The building blocks that enable the AI to understand what people are actually saying. (Hint: “mhm” and “yuck” are not always easy to interpret.)
- Finetuning – The customization that makes your agent an expert in your industry, your customers, and your language. This means the agent can actually understand industry jargon, interpret dialects, and use your tone of voice. Without finetuning, there's a risk that customers feel talked to by a robot – not an advisor.
Are you dropping these? Congratulations – then you just have a glorified chatbot with a microphone.
The checklist
When choosing a Voice AI provider, these are the points you MUST check – otherwise, you might as well leave it alone:
- Data Security & GDPR – Where does your customers' voice end up? (Spoiler: “USA somewhere” is the wrong answer.)
- Integrations – Does the agent communicate with your CRM, or just pretend to?
- Voice Experience – Does the voice sound human? Or an old GPS from 2008?
- Customization – Can the agent have your tone of voice – or will it sound like a customer service robot from a budget chain?
Delays – the hidden dealbreaker
Here is the truth: You may have the world's best voice, the most advanced integrations, and perfect language understanding. But if the agent takes too long to respond, everything will fall apart.
Delays of just 1–2 seconds can make the conversation awkward and unusable. It feels like talking on a walkie-talkie: “Over and out.” No customers will tolerate that.
A professional Voice AI must respond instantly. The response should feel as natural as when you talk to a human. That's why we at Threll.ai have worked tirelessly to reduce latency – so that Threller's voice sounds seamless and real.
Background noise – the invisible enemy
Chatting with an AI on your keyboard is simple: plain text in, plain text out.
But in reality, your customers are speaking via phone – and that makes the sound quality chaotic:
- Traffic in the background
- Children shouting
- Poor headphones
- Poor coverage
All of this can undermine the AI's ability to understand what is being said.
Therefore, sound quality and noise management are absolutely essential in Voice AI. If your system cannot filter out background noise, you'll have frustrating customers and misunderstandings.
At Threll.ai, we have built Voice Threller that is trained on real, imperfect conversations. This means they don't just work in a quiet conference room – but also in the customer's daily life.
What does this mean for you?
Choosing Voice AI is like buying a car:
At the dealership, everyone looks good, but it's only on the road that you notice if the engine really holds up.
At Threll.ai we are building Voice Threller from the ground up – with Norwegian conditions in our DNA. We know languages, we understand culture, and we have the integrations that make the solution work in practice.
The conclusion (without filter)
Don't be fooled by demos.
Don't buy into the hype.
Use the checklist above – and choose a provider who can actually do this.
