According to the article, AI assistants are transforming the in-car experience by switching from command systems to conversation-driven assistants based on large language models. The in-car voice assistant industry is expected to be worth $3.27 billion in 2026 and to amount to $5.49 billion in 2029 with an annual rate of 13.9%. This change carries commercial value, as an engaging AI experience is emerging as a key differentiator affecting purchasing decisions, subscription plans, and brand loyalty. The technical leap involves large language models replacing older rule-based voice systems, enabling multi-step, conversational requests that build on each other. This natural-language capability depends on a pipeline of technologies including Automatic Speech Recognition, Natural Language Understanding, and real-time data sources.
