Nowadays, almost every car's dashboard comes with a voice recognition system, which enables drivers to control music volumes, change radio stations, add Bluetooth devices, turn inside lights on and off, and more. Since Microsoft Sync introduced the VUI in Ford cars in 2007, there has not been much technological advancement. In 2007, Microsoft Sync was ahead of the times, introducing the first of its kind voice-enabled features in cars, but designing VUIs for Ford had some challenges. First, there was the noise factor while driving at high speed, which hindered the driver's voice from being recognized. Second, being able to upgrade required bringingthe car in to a dealer. Third, the car operating system was usually proprietary, hence it was difficult to write programs to introduce new features or enhance existing features.
In 2017, many challenges faced by Microsoft Sync were eliminated. Many cars had more soundproof bodies, which eliminated many of the road noises. Tesla has shown us that, with the right design, a car's system software can be upgraded via Wi-Fi, and many manufacturers have begun to allow car systems to be remotely upgraded. In 2018, many manufacturers began to integrate Google Auto and Apple CarPlay by taking advantage of the Android and iOS operating systems, which have proven track records in the mobile space. Also, car manufacturers taking advantage of Android and iOS brings entire ecosystems of developers together, who can bring innovation by developing voice-enabled applications for cars. For example, there is a project on GitHub (http://bit.ly/2D83MjI) that integrates the Tesla API into Google Home and into mobile devices via Google Assistant, which allows you to check the battery charge level, door status, flash the lights, and honk the horn. Just as developers have brought innovations through applications in the Android and iOS marketplaces, you will see a huge surge in voice-enabled applications in the Google Auto and Apple CarPlay marketplaces. Besides car manufacturers, in 2018, you will begin to see many car stereo manufacturers, such as Pioneer, Alpine, JVC, Kenwood, Sony, and others, begin to support Google Auto as well.
