How does a voicebot work?

Voicebots are based on modern technologies such as natural language processing (NLP) and artificial intelligence (AI). The telephone, for example, can serve as an input or output channel. NLP helps to recognize and understand spoken language, classify its content, and respond appropriately.

The process begins with the conversion of speech to text (speech-to-text). The AI then interprets the request, recognizes the issue, and derives an appropriate response. This is then converted back into speech (text-to-speech).

The continuous development of AI-based models has led to voicebots now working very precisely and appearing almost human in many situations. Machine learning enables them to improve with every interaction, increasingly recognize emotional nuances in language, and often perform speech-to-text and text-to-speech directly themselves—without having to go through a telephony provider.

Typical use cases for voicebots

• Counter reading: Report meter readings by voice—no manual entry required.

• Invoice inquiries: Automatically clarify open invoices, payment deadlines, or advance payments.

• Fault reports: Record faults 24/7 and initiate follow-up processes (e.g., forwarding to support).

• Tariff advice: Present suitable tariffs and display personalized offers.

• Status queries: Provide information on moves, contract changes, or ongoing repairs.

In addition, contract management, energy consulting, and customer loyalty management can also be easily mapped.

In which sectors are voicebots viable for the future? In almost all industries—especially those where there are many recurring inquiries, clear processes, and high availability are required.

Which advantages do voicebots offer for companies?

Voicebots make communication faster and more efficient: they process many requests automatically, reliably, and without queues—around the clock. This increases customer satisfaction, reduces the workload on teams, and lowers costs. At the same time, voicebots create direct, personal access to customers, e.g., for meter readings, address changes, cancellations, status queries, or information output. In addition, processes are more scalable, peak loads can be cushioned, and the quality of responses remains consistent.

Companies that start using a voicebot early on do not only gain an additional service channel, but also gradually build a future-proof communication base: They gather valuable insights from real conversations, optimize processes based on data, and can continuously expand the bot—from simple self-service to personalized, intelligent dialogues. This turns a quick relief in day-to-day business into a measurable competitive advantage in the long term.
