Aristech in use at SWR, WDR and hr

What exactly do voicebots do on the radio? You can’t hear them directly on air. Nevertheless, they play an important role behind the scenes: they help traffic hotlines to provide up-to-date traffic updates automatically and via voice.

At broadcasters such as SWR, WDR and Hessischer Rundfunk, Aristech’s voice solutions ensure that callers quickly receive the information they need. This is made possible by combining speech recognition with text-to-speech technology.

Check traffic updates easily using voice commands

Anyone who needs information about traffic jams, roadworks or road closures whilst on the move doesn’t want to have to navigate through lengthy menus. Modern voice agents make it much easier to get the information you need: callers simply say the name of the motorway or category they’re looking for, and the relevant traffic information is then read out to them.

One example is Hessischer Rundfunk’s traffic hotline. Anyone wishing to find out about traffic disruptions within the HR broadcast area can simply state a motorway such as ‘A5’ or select the ‘Other reports’ option after the initial prompt. The system recognises the request and automatically reads out the available reports.

How the technology behind it works

The solution combines two key voice technologies:

Speech recognition identifies what callers are saying, such as a motorway number or a specific traffic category.

Text-to-speech then converts the relevant traffic updates into natural-sounding speech.

This creates an automated voice dialogue that is available 24/7 and operates without the usual waiting times.

More service, fewer distractions

When you’re on the road, quick and easy access to traffic information is essential. Voice-activated queries cut out unnecessary steps and make it easier to access the latest updates.

This makes things more convenient and can also help to reduce distractions whilst driving.

Benefits for broadcasters and transport services

The use of voicebots also offers significant benefits for radio stations and traffic services. Enquiries can be received and answered automatically. This takes the pressure off existing helpline systems and ensures that traffic information remains reliably accessible even when call volumes are high.

At the same time, the service remains user-friendly: instead of rigid telephone menus, it offers natural access via voice.

German speech technology in use at SWR, WDR and Hessischer Rundfunk

Aristech’s voicebots are already supporting the traffic hotlines of SWR, WDR and hr. They help to provide traffic information more quickly, efficiently and accessibly.

These projects demonstrate how conversational AI delivers real benefits in everyday life: not as an abstract technology of the future, but as a practical solution to a specific need.

Conclusion

Voicebots demonstrate how modern voice technology adds real value to everyday life. They make traffic information more easily accessible by phone, reduce waiting times and enable intuitive voice-based enquiries.

In this way, Aristech helps radio stations make their traffic hotlines more efficient, user-friendly and future-proof.
