What is In-Car Speech Recognition?: Definition, use cases and future

The future of In-Car Speech Recognition

Speech recognition is one of the most exciting technologies in the market today. It has been around for over a decade now. The technology has seen a lot of growth with the likes of Siri and Google Assistant.

Speech recognition is making its way into cars, and it’s one of their most under-utilized features. Given the amount of driving that the average person does, it makes sense to use this technology to make driving safer and more comfortable.

The automotive industry is evolving, and the daily commute is changing. A car is capable of acting as a smart device, and, like other smart devices, speech recognition technology is becoming a commonplace in-car feature. This technology makes it easier and safer for drivers to use their vehicles while remaining focused on the road.

In this blog, we look at the different aspects of the in-car speech recognition market and what the recent trends have been.

What is In-Car Speech Recognition?


In-car speech recognition is a technology that allows drivers to interact with their vehicles using voice commands. This can be used for various purposes, such as making phone calls, sending text messages, playing music, and navigating.

In-car speech recognition systems use training data and a combination of artificial intelligence, machine learning, and hardware to process the dataset and interpret the driver’s voice commands.

The software understands the driver’s intent and converts it into instructions that the car’s systems can execute. The hardware translates the driver’s speech into text.

With the availability of multilingual speech data, automatic speech recognition systems are gaining popularity as they offer a way for drivers speaking different languages to interact with their cars.

There are some concerns about the safety of these systems, as they can be distracting and may not be able to interpret the driver’s commands. The technology is still far from perfect for other languages than English, but is gaining momentum with the availability of data solutions increasing every year.

How Can In-Car Speech Recognition Help?

Common use cases for Voice AI in Auto


In-car speech recognition can help reduce a driver’s time looking at a screen or inputting data. It provides a hands-free way to interact with a car’s infotainment system. In-car speech recognition can help to make the driving experience safer and more convenient.

Few of the ways that in-car speech recognition can help drivers include:

  • Making hands-free phone calls
  • Sending and receiving text messages
  • Getting directions and navigation
  • Searching the internet
  • Controlling in-car entertainment systems
  • Opening and closing the car doors

Top Players of Voice Recognition Technology in Automobiles

There are many voice recognition technology providers in the automotive industry. But, there are a few service providers that have become more prominent in the speech recognition industry. Here are the top three players in the voice technology space:

  1. Nuance Communications: Nuance is a leading speech recognition technology provider for automobiles. They invest in world class R&D division to provide intelligent solutions. BMW, Audi, and Fort are some of the big names that use Nuance’s speech recognition software.
  1. Microsoft – In 2016, Microsoft announced strategic partnerships with Toyota and Nissan that would allow users to use Cortana (Microsoft’s voice assistant) in their cars.
  1. Google: Google is a significant player in the voice recognition technology space. They offer a wide range of solutions that allow drivers to control their vehicles using their voice.

The Future of In-Car Speech Recognition

The future of in-car speech recognition looks very promising. With the advancements in artificial intelligence and natural language processing, the accuracy and usability of in-car speech recognition systems will improve.

According to Automotive World, by 2028, 90% of new vehicles sold globally will have in-car voice control embedded. As the technology develops, in-car speech recognition will likely become even more sophisticated.

In the future, we may see cars that can understand and respond to more complex commands and provide a more natural experience with conversational AI. This could make driving even more efficient and enjoyable.

According to Capgemini, in the future, more people are expected to use voice assistants in their cars. In fact, 73% of people said they would use assistants, compared to the 49% who use them today.

As cars become connected, it’s also likely that in-car speech recognition will become more integrated with other systems in the vehicle. For example, we may see cars that can adjust settings based on the driver’s preferences or that can provide information about the current traffic situation.


New voice technology advancements are here to stay. They will only continue to grow in popularity, making now the perfect time to get ahead of the curve and start creating innovative voice experiences for drivers.

As car manufacturers integrate speech recognition into their cars, this opens up a new world of possibilities for the technology and its users.
