Voice computer

What is a voice computer?

A voice computer is a technical system that specializes in processing natural language. It combines speech recognition (Automatic Speech Recognition, ASR) and speech synthesis (Text-to-Speech, TTS) to convert spoken language into text – and vice versa. Modern voice computers thus enable bidirectional speech communication between man and machine. They form the basis for voice-controlled systems in a wide range of application areas, particularly in automated dialog systems, virtual assistants and customer service.

Central functions of a voicecomputer

A voice computer usually consists of several functional components:

• Speech recognition (ASR): It analyzes spoken language, converts it into text and thus enables machine processing of what has been said.

• Speech synthesis (TTS): This function generates natural, spoken language from written text in order to provide the user with acoustic feedback.

• Dialogue control: Dialogue logic controls the course of the conversation and coordinates which answers the voice computer gives – for example using rules, decision trees or AI-supported models.

Areas of application

Voice computers are used in many areas where speech is used as a natural interface:

• IVR systems (Interactive Voice Response): Automated voice menus in telephone hotlines that answer and forward calls or provide information.

• Virtual assistants: Voice-controlled systems such as Siri, Alexa or Google Assistant that respond to questions or commands and perform tasks.

• Automated customer service: Voice computers handle simple service requests, such as making appointments, checking account balances or tracking orders – around the clock, without human agents.

Advantages of voice computers

The use of voice computers brings numerous advantages, especially in the context of contact centers and self-service solutions:

• Automation of standard processes: voice computers relieve the burden on human employees by taking over repetitive tasks.

• 24/7 availability: They are available at all times, regardless of business hours or staffing.

• User-friendliness: Voice control enables intuitive interaction, especially for less technically experienced user groups.
