🔵⚪️ The Alexa Factor
Weekly news digest curated by the industry insiders
📝 Editorial
Very few projects have had most direct influence in natural language understanding (NLU) and automatic speech recognition (ASR) research than Amazon’s Alexa. Undisputedly considered one of the top two digital assistants in the world, Alexa is used in highly heterogenous devices from mobile phones to cars. The ubiquitous adoption gives Alexa a unique footprint to apply NLU and ASR methods across different languages, environments and interaction modes. Not surprisingly, Alexa has become one of the top environment for evaluating and deploying new ASR-NLU ideas.
The breadth and depth of NLU-ASR research applied in Alexa challenges is mindboggling. From interactions in low-resource languages, multi-task models to insanely advance methods to improve the quality of speech, Alexa applies hundreds of NLU-ASR models at scale. Just last week, Amazon Research published three new papers about NLU-ASR research applied in Alexa. One of the papers focuses on recognizing intents in unexplored domains which is super relevant to establish broader conversations. Another paper covered the difficult area of dynamic personalization that could be used to tailor a conversation where Alexa learns more info from a client. Finally, the third paper proposes a graph neural networks method to improve the matching of recipes to customer requests.
This is just one week in NLU-ASR research applied to Alexa. Without a doubt, Alexa has become an important factor and one of the most fertile environments for accelerating NLU-ASR research in the current market.
