The automotive industry continues to be a hotbed of innovation, with activity driven by speech recognition digital assistants, improved wireless voice technology, user-friendliness and better connectivity, and growing importance of technologies such as natural language processing (NLP), text-to-speech (TTS), automated speech recognition (ASR). In the last three years alone, there have been over 1.2 million patents filed and granted in the automotive industry, according to GlobalData’s report on Cloud in Automotive: Speech recognition techniques. Buy the report here.

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early emergence to accelerating adoption, before finally stabilising and reaching maturity.

Identifying where a particular innovation is on this journey, especially those that are in the emerging and accelerating stages, is essential for understanding their current level of adoption and the likely future trajectory and impact they will have.

290+ innovations will shape the automotive industry

According to GlobalData’s Technology Foresights, which plots the S-curve for the automotive industry using innovation intensity models built on over 619,000 patents, there are 290+ innovation areas that will shape the future of the industry.

Within the emerging innovation stage, EV discharge prediction, manufacturability analysis, and AI-assisted CAD are disruptive technologies that are in the early stages of application and should be tracked closely. Vehicle head up displays (HUDs), gesture-sensing AR/VR interfaces, and instrument cluster dashboard are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are HUD dashboards and remote trip monitoring, which are now well established in the industry.

Innovation S-curve for cloud in the automotive industry

Speech recognition techniques is a key innovation area in cloud

Speech recognition comprises three methods: extraction of acoustic indices from the speech signal, evaluation of the probability that the perceived index string was triggered by a hypothesised utterance segment, and determination of the recognised utterance via a search among hypothesised alternatives.

GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies. According to GlobalData, there are 10+ companies, spanning technology vendors, established automotive companies, and up-and-coming start-ups engaged in the development and application of speech recognition techniques.

Key players in speech recognition techniques – a disruptive innovation in the automotive industry

‘Application diversity’ measures the number of different applications identified for each relevant patent and broadly splits companies into either ‘niche’ or ‘diversified’ innovators.

‘Geographic reach’ refers to the number of different countries each relevant patent is registered in and reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.
