A KItelephone bot can be an extremely powerful tool – but only if it is properly implemented and operated. A badly configured bot can frustrate customers and harm the corporate image. We show the 10 most common mistakes and give tips on how to avoid them from the beginning.

Top 10 Overview errors

Short: **The caller is not informed that he is talking to an AI.

**The caller is not informed that he is talking to an AI. This leads to confusion and mistrust.

To complex dialogues: The attempt to automate too many complex tasks at once overwhelms the bot and the caller.
No escalation option: The caller has no way of switching to a human employee if the messenger does not understand the concern.
Sleep speech recognition: The bot does not understand the caller due to background noise, dialects or unclear pronunciation.
Unnatural voice and language: A robotic voice and an impersonal language scare callers.
**The bot is not connected to relevant systems (CRM, calendar) and therefore cannot provide personalised or fall-close answers.
Inadequate test phase: The bot goes live without having been extensively tested on various scenarios.
No continuous monitoring: After the live gear, the performance of the bot is not monitored and optimized.
Ignoring customer feedback: Analysis of conversation breaks or direct customer feedback is neglected.
False expectations: The assumption that the bot can handle 100% of all calls perfectly from the start.

A good AI telephone bot is not a unique project, but a continuous process of optimization.

Be transparent: Tell the caller to start talking to a digital assistant.
Start simply: Start with automation of 2-3 simple but frequent call reasons.
** Always have an escalation option:** Give the caller the opportunity to talk to a person at any time (e.g. by saying "employees").
** Choose a provider with good speech recognition:** Pay attention to a high detection rate, even in difficult conditions.
Investing into a natural voice: A pleasant voice and a friendly language increase acceptance.
Plan integrations from the start: A connection to your core systems is crucial for success.
Test, test, test: Conduct comprehensive tests with your team before the bot goes live.
** Monitor and learn:** Analyze the interview data regularly and optimize the dialogues.
